+ *      Responsible for OOM reporting when null is returned.
+ *  - template <typename T> T* pod_calloc(size_t)

+ *      to allocate more than the available memory space -- think allocating an
+ *      array of large-size objects, where N * size overflows) before null is

+ *      Clients (such as this hypothetical append method implementation) should
+ *      call this method in situations that don't allocate, but could generally,

+ * An enum of memory ordering possibilities for atomics.
+ *
+ * Memory ordering is the observable state of distinct values in memory.
+ * (It's a separate concept from atomicity, which concerns whether an
+ * operation can ever be observed in an intermediate state.  Don't
+ * conflate the two!)  Given a sequence of operations in source code on
+ * memory, it is *not* always the case that, at all times and on all
+ * cores, those operations will appear to have occurred in that exact
+ * sequence.  First, the compiler might reorder that sequence, if it
+ * thinks another ordering will be more efficient.  Second, the CPU may
+ * not expose so consistent a view of memory.  CPUs will often perform
+ * their own instruction reordering, above and beyond that performed by
+ * the compiler.  And each core has its own memory caches, and accesses
+ * (reads and writes both) to "memory" may only resolve to out-of-date
+ * cache entries -- not to the "most recently" performed operation in
+ * some global sense.  Any access to a value that may be used by
+ * multiple threads, potentially across multiple cores, must therefore
+ * have a memory ordering imposed on it, for all code on all
+ * threads/cores to have a sufficiently coherent worldview.
+ *
+ * http://gcc.gnu.org/wiki/Atomic/GCCMM/AtomicSync and
+ * http://en.cppreference.com/w/cpp/atomic/memory_order go into more
+ * detail on all this, including examples of how each mode works.
+ *
+ * Note that for simplicity and practicality, not all of the modes in
+ * C++11 are supported.  The missing C++11 modes are either subsumed by
+ * the modes we provide below, or not relevant for the CPUs we support
+ * in Gecko.  These three modes are confusing enough as it is!
+ */
+enum MemoryOrdering {
+  /*
+   * Relaxed ordering is the simplest memory ordering: none at all.
+   * When the result of a write is observed, nothing may be inferred
+   * about other memory.  Writes ostensibly performed "before" on the
+   * writing thread may not yet be visible.  Writes performed "after" on
+   * the writing thread may already be visible, if the compiler or CPU
+   * reordered them.  (The latter can happen if reads and/or writes get
+   * held up in per-processor caches.)  Relaxed ordering means
+   * operations can always use cached values (as long as the actual
+   * updates to atomic values actually occur, correctly, eventually), so
+   * it's usually the fastest sort of atomic access.  For this reason,
+   * *it's also the most dangerous kind of access*.
+   *
+   * Relaxed ordering is good for things like process-wide statistics
+   * counters that don't need to be consistent with anything else, so
+   * long as updates themselves are atomic.  (And so long as any
+   * observations of that value can tolerate being out-of-date -- if you
+   * need some sort of up-to-date value, you need some sort of other
+   * synchronizing operation.)  It's *not* good for locks, mutexes,
+   * reference counts, etc. that mediate access to other memory, or must
+   * be observably consistent with other memory.
+   *
+   * x86 architectures don't take advantage of the optimization
+   * opportunities that relaxed ordering permits.  Thus it's possible
+   * that using relaxed ordering will "work" on x86 but fail elsewhere
+   * (ARM, say, which *does* implement non-sequentially-consistent
+   * relaxed ordering semantics).  Be extra-careful using relaxed
+   * ordering if you can't easily test non-x86 architectures!
+   */
+  Relaxed,
+
+  /*
+   * When an atomic value is updated with ReleaseAcquire ordering, and
+   * that new value is observed with ReleaseAcquire ordering, prior
+   * writes (atomic or not) are also observable.  What ReleaseAcquire
+   * *doesn't* give you is any observable ordering guarantees for
+   * ReleaseAcquire-ordered operations on different objects.  For
+   * example, if there are two cores that each perform ReleaseAcquire
+   * operations on separate objects, each core may or may not observe
+   * the operations made by the other core.  The only way the cores can
+   * be synchronized with ReleaseAcquire is if they both
+   * ReleaseAcquire-access the same object.  This implies that you can't
+   * necessarily describe some global total ordering of ReleaseAcquire
+   * operations.
+   *
+   * ReleaseAcquire ordering is good for (as the name implies) atomic
+   * operations on values controlling ownership of things: reference
+   * counts, mutexes, and the like.  However, if you are thinking about
+   * using these to implement your own locks or mutexes, you should take
+   * a good, hard look at actual lock or mutex primitives first.
+   */
+  ReleaseAcquire,
+
+  /*
+   * When an atomic value is updated with SequentiallyConsistent
+   * ordering, all writes observable when the update is observed, just
+   * as with ReleaseAcquire ordering.  But, furthermore, a global total
+   * ordering of SequentiallyConsistent operations *can* be described.
+   * For example, if two cores perform SequentiallyConsistent operations
+   * on separate objects, one core will observably perform its update
+   * (and all previous operations will have completed), then the other
+   * core will observably perform its update (and all previous
+   * operations will have completed).  (Although those previous
+   * operations aren't themselves ordered -- they could be intermixed,
+   * or ordered if they occur on atomic values with ordering
+   * requirements.)  SequentiallyConsistent is the *simplest and safest*
+   * ordering of atomic operations -- it's always as if one operation
+   * happens, then another, then another, in some order -- and every
+   * core observes updates to happen in that single order.  Because it
+   * has the most synchronization requirements, operations ordered this
+   * way also tend to be slowest.
+   *
+   * SequentiallyConsistent ordering can be desirable when multiple
+   * threads observe objects, and they all have to agree on the
+   * observable order of changes to them.  People expect
+   * SequentiallyConsistent ordering, even if they shouldn't, when
+   * writing code, atomic or otherwise.  SequentiallyConsistent is also
+   * the ordering of choice when designing lockless data structures.  If
+   * you don't know what order to use, use this one.

+ *   void PureFunction() const MOZ_FUNCTION_ATTRIBUTE = 0;
+ *   void OverriddenFunction() MOZ_FUNCTION_ATTIRBUTE override;
+ *
+ * Attributes that apply to variables or parameters follow the variable's name:
+ *
+ *   int variable MOZ_VARIABLE_ATTRIBUTE;
+ *
+ * Attributes that apply to types follow the type name:
+ *
+ *   typedef int MOZ_TYPE_ATTRIBUTE MagicInt;
+ *   int MOZ_TYPE_ATTRIBUTE someVariable;
+ *   int* MOZ_TYPE_ATTRIBUTE magicPtrInt;
+ *   int MOZ_TYPE_ATTRIBUTE* ptrToMagicInt;
+ *
+ * Attributes that apply to statements precede the statement:
+ *
+ *   MOZ_IF_ATTRIBUTE if (x == 0)
+ *   MOZ_DO_ATTRIBUTE do { } while (0);
+ *
+ * Attributes that apply to labels precede the label:
+ *
+ *   MOZ_LABEL_ATTRIBUTE target:
+ *     goto target;
+ *   MOZ_CASE_ATTRIBUTE case 5:
+ *   MOZ_DEFAULT_ATTRIBUTE default:
+ *
+ * The static analyses that are performed by the plugin are as follows:
+ *
+ * MOZ_MUST_OVERRIDE: Applies to all C++ member functions. All immediate
+ *   subclasses must provide an exact override of this method; if a subclass
+ *   does not override this method, the compiler will emit an error. This
+ *   attribute is not limited to virtual methods, so if it is applied to a
+ *   nonvirtual method and the subclass does not provide an equivalent
+ *   definition, the compiler will emit an error.
+ * MOZ_STACK_CLASS: Applies to all classes. Any class with this annotation is
+ *   expected to live on the stack, so it is a compile-time error to use it, or
+ *   an array of such objects, as a global or static variable, or as the type of
+ *   a new expression (unless placement new is being used). If a member of
+ *   another class uses this class, or if another class inherits from this
+ *   class, then it is considered to be a stack class as well, although this
+ *   attribute need not be provided in such cases.
+ * MOZ_NONHEAP_CLASS: Applies to all classes. Any class with this annotation is
+ *   expected to live on the stack or in static storage, so it is a compile-time
+ *   error to use it, or an array of such objects, as the type of a new
+ *   expression. If a member of another class uses this class, or if another
+ *   class inherits from this class, then it is considered to be a non-heap class
+ *   as well, although this attribute need not be provided in such cases.
+ * MOZ_HEAP_CLASS: Applies to all classes. Any class with this annotation is
+ *   expected to live on the heap, so it is a compile-time error to use it, or
+ *   an array of such objects, as the type of a variable declaration, or as a
+ *   temporary object. If a member of another class uses this class, or if
+ *   another class inherits from this class, then it is considered to be a heap
+ *   class as well, although this attribute need not be provided in such cases.
+ * MOZ_NON_TEMPORARY_CLASS: Applies to all classes. Any class with this
+ *   annotation is expected not to live in a temporary. If a member of another
+ *   class uses this class or if another class inherits from this class, then it
+ *   is considered to be a non-temporary class as well, although this attribute
+ *   need not be provided in such cases.
+ * MOZ_RAII: Applies to all classes. Any class with this annotation is assumed
+ *   to be a RAII guard, which is expected to live on the stack in an automatic
+ *   allocation. It is prohibited from being allocated in a temporary, static
+ *   storage, or on the heap. This is a combination of MOZ_STACK_CLASS and
+ *   MOZ_NON_TEMPORARY_CLASS.
+ * MOZ_ONLY_USED_TO_AVOID_STATIC_CONSTRUCTORS: Applies to all classes that are
+ *   intended to prevent introducing static initializers.  This attribute
+ *   currently makes it a compile-time error to instantiate these classes
+ *   anywhere other than at the global scope, or as a static member of a class.
+ *   In non-debug mode, it also prohibits non-trivial constructors and
+ *   destructors.
+ * MOZ_TRIVIAL_CTOR_DTOR: Applies to all classes that must have both a trivial
+ *   or constexpr constructor and a trivial destructor. Setting this attribute
+ *   on a class makes it a compile-time error for that class to get a
+ *   non-trivial constructor or destructor for any reason.
+ * MOZ_HEAP_ALLOCATOR: Applies to any function. This indicates that the return
+ *   value is allocated on the heap, and will as a result check such allocations
+ *   during MOZ_STACK_CLASS and MOZ_NONHEAP_CLASS annotation checking.
+ * MOZ_IMPLICIT: Applies to constructors. Implicit conversion constructors
+ *   are disallowed by default unless they are marked as MOZ_IMPLICIT. This
+ *   attribute must be used for constructors which intend to provide implicit
+ *   conversions.
+ * MOZ_NO_ARITHMETIC_EXPR_IN_ARGUMENT: Applies to functions. Makes it a compile
+ *   time error to pass arithmetic expressions on variables to the function.
+ * MOZ_OWNING_REF: Applies to declarations of pointers to reference counted
+ *   types.  This attribute tells the compiler that the raw pointer is a strong
+ *   reference, where ownership through methods such as AddRef and Release is
+ *   managed manually.  This can make the compiler ignore these pointers when
+ *   validating the usage of pointers otherwise.
+ *
+ *   Example uses include owned pointers inside of unions, and pointers stored
+ *   in POD types where a using a smart pointer class would make the object
+ *   non-POD.
+ * MOZ_NON_OWNING_REF: Applies to declarations of pointers to reference counted
+ *   types.  This attribute tells the compiler that the raw pointer is a weak
+ *   reference, which is ensured to be valid by a guarantee that the reference
+ *   will be nulled before the pointer becomes invalid.  This can make the compiler
+ *   ignore these pointers when validating the usage of pointers otherwise.
+ *
+ *   Examples include an mOwner pointer, which is nulled by the owning class's
+ *   destructor, and is null-checked before dereferencing.
+ * MOZ_UNSAFE_REF: Applies to declarations of pointers to reference counted types.
+ *   Occasionally there are non-owning references which are valid, but do not take
+ *   the form of a MOZ_NON_OWNING_REF.  Their safety may be dependent on the behaviour
+ *   of API consumers.  The string argument passed to this macro documents the safety
+ *   conditions.  This can make the compiler ignore these pointers when validating
+ *   the usage of pointers elsewhere.
+ *
+ *   Examples include an nsIAtom* member which is known at compile time to point to a
+ *   static atom which is valid throughout the lifetime of the program, or an API which
+ *   stores a pointer, but doesn't take ownership over it, instead requiring the API
+ *   consumer to correctly null the value before it becomes invalid.
+ *
+ *   Use of this annotation is discouraged when a strong reference or one of the above
+ *   two annotations can be used instead.
+ * MOZ_NO_ADDREF_RELEASE_ON_RETURN: Applies to function declarations.  Makes it
+ *   a compile time error to call AddRef or Release on the return value of a
+ *   function.  This is intended to be used with operator->() of our smart
+ *   pointer classes to ensure that the refcount of an object wrapped in a
+ *   smart pointer is not manipulated directly.
+ * MOZ_MUST_USE_TYPE: Applies to type declarations.  Makes it a compile time
+ *   error to not use the return value of a function which has this type.  This
+ *   is intended to be used with types which it is an error to not use.
+ * MOZ_NEEDS_NO_VTABLE_TYPE: Applies to template class declarations.  Makes it
+ *   a compile time error to instantiate this template with a type parameter which
+ *   has a VTable.
+ * MOZ_NON_MEMMOVABLE: Applies to class declarations for types that are not safe
+ *   to be moved in memory using memmove().
+ * MOZ_NEEDS_MEMMOVABLE_TYPE: Applies to template class declarations where the
+ *   template arguments are required to be safe to move in memory using
+ *   memmove().  Passing MOZ_NON_MEMMOVABLE types to these templates is a
+ *   compile time error.
+ * MOZ_NEEDS_MEMMOVABLE_MEMBERS: Applies to class declarations where each member
+ *   must be safe to move in memory using memmove().  MOZ_NON_MEMMOVABLE types
+ *   used in members of these classes are compile time errors.
+ * MOZ_INHERIT_TYPE_ANNOTATIONS_FROM_TEMPLATE_ARGS: Applies to template class
+ *   declarations where an instance of the template should be considered, for
+ *   static analysis purposes, to inherit any type annotations (such as
+ *   MOZ_MUST_USE_TYPE and MOZ_STACK_CLASS) from its template arguments.
+ * MOZ_INIT_OUTSIDE_CTOR: Applies to class member declarations. Occasionally
+ *   there are class members that are not initialized in the constructor,
+ *   but logic elsewhere in the class ensures they are initialized prior to use.
+ *   Using this attribute on a member disables the check that this member must be
+ *   initialized in constructors via list-initialization, in the constructor body,
+ *   or via functions called from the constructor body.
+ * MOZ_IS_CLASS_INIT: Applies to class method declarations. Occasionally the
+ *   constructor doesn't initialize all of the member variables and another function
+ *   is used to initialize the rest. This marker is used to make the static analysis
+ *   tool aware that the marked function is part of the initialization process
+ *   and to include the marked function in the scan mechanism that determines witch
+ *   member variables still remain uninitialized.
+ * MOZ_NON_PARAM: Applies to types. Makes it compile time error to use the type
+ *   in parameter without pointer or reference.
+ * MOZ_NON_AUTOABLE: Applies to class declarations. Makes it a compile time error to
+ *   use `auto` in place of this type in variable declarations.  This is intended to
+ *   be used with types which are intended to be implicitly constructed into other
+ *   other types before being assigned to variables.
+ * MOZ_REQUIRED_BASE_METHOD: Applies to virtual class method declarations.
+ *  Sometimes derived classes override methods that need to be called by their
+ *  overridden counterparts. This marker indicates that the marked method must
+ *  be called by the method that it overrides.

+ *
+ * The filter is parametrized on KeySize, which is the size of the key

+/**
+ * @class CheckedInt
+ * @brief Integer wrapper class checking for integer overflow and other errors
+ * @param T the integer type to wrap. Can be any type among the following:
+ *            - any basic integer type such as |int|
+ *            - any stdint type such as |int8_t|
+ *
+ * This class implements guarded integer arithmetic. Do a computation, check
+ * that isValid() returns true, you then have a guarantee that no problem, such
+ * as integer overflow, happened during this computation, and you can call
+ * value() to get the plain integer value.
+ *
+ * The arithmetic operators in this class are guaranteed not to raise a signal
+ * (e.g. in case of a division by zero).
+ *
+ * For example, suppose that you want to implement a function that computes
+ * (aX+aY)/aZ, that doesn't crash if aZ==0, and that reports on error (divide by
+ * zero or integer overflow). You could code it as follows:
+   @code
+   bool computeXPlusYOverZ(int aX, int aY, int aZ, int* aResult)
+   {
+     CheckedInt<int> checkedResult = (CheckedInt<int>(aX) + aY) / aZ;
+     if (checkedResult.isValid()) {
+       *aResult = checkedResult.value();
+       return true;
+     } else {
+       return false;
+     }
+   }
+   @endcode
+ *
+ * Implicit conversion from plain integers to checked integers is allowed. The
+ * plain integer is checked to be in range before being casted to the
+ * destination type. This means that the following lines all compile, and the
+ * resulting CheckedInts are correctly detected as valid or invalid:
+ * @code
+   // 1 is of type int, is found to be in range for uint8_t, x is valid
+   CheckedInt<uint8_t> x(1);
+   // -1 is of type int, is found not to be in range for uint8_t, x is invalid
+   CheckedInt<uint8_t> x(-1);
+   // -1 is of type int, is found to be in range for int8_t, x is valid
+   CheckedInt<int8_t> x(-1);
+   // 1000 is of type int16_t, is found not to be in range for int8_t,
+   // x is invalid
+   CheckedInt<int8_t> x(int16_t(1000));
+   // 3123456789 is of type uint32_t, is found not to be in range for int32_t,
+   // x is invalid
+   CheckedInt<int32_t> x(uint32_t(3123456789));
+ * @endcode
+ * Implicit conversion from
+ * checked integers to plain integers is not allowed. As shown in the
+ * above example, to get the value of a checked integer as a normal integer,
+ * call value().
+ *
+ * Arithmetic operations between checked and plain integers is allowed; the
+ * result type is the type of the checked integer.
+ *
+ * Checked integers of different types cannot be used in the same arithmetic
+ * expression.
+ *
+ * There are convenience typedefs for all stdint types, of the following form
+ * (these are just 2 examples):
+   @code
+   typedef CheckedInt<int32_t> CheckedInt32;
+   typedef CheckedInt<uint16_t> CheckedUint16;

+/* Functions for reading and writing integers in various endiannesses. */
+
+/*
+ * The classes LittleEndian and BigEndian expose static methods for
+ * reading and writing 16-, 32-, and 64-bit signed and unsigned integers
+ * in their respective endianness.  The naming scheme is:
+ *
+ * {Little,Big}Endian::{read,write}{Uint,Int}<bitsize>
+ *
+ * For instance, LittleEndian::readInt32 will read a 32-bit signed
+ * integer from memory in little endian format.  Similarly,
+ * BigEndian::writeUint16 will write a 16-bit unsigned integer to memory
+ * in big-endian format.
+ *
+ * The class NativeEndian exposes methods for conversion of existing
+ * data to and from the native endianness.  These methods are intended
+ * for cases where data needs to be transferred, serialized, etc.
+ * swap{To,From}{Little,Big}Endian byteswap a single value if necessary.
+ * Bulk conversion functions are also provided which optimize the
+ * no-conversion-needed case:
+ *
+ * - copyAndSwap{To,From}{Little,Big}Endian;
+ * - swap{To,From}{Little,Big}EndianInPlace.
+ *
+ * The *From* variants are intended to be used for reading data and the
+ * *To* variants for writing data.
+ *
+ * Methods on NativeEndian work with integer data of any type.
+ * Floating-point data is not supported.
+ *
+ * For clarity in networking code, "Network" may be used as a synonym
+ * for "Big" in any of the above methods or class names.
+ *
+ * As an example, reading a file format header whose fields are stored
+ * in big-endian format might look like:
+ *
+ * class ExampleHeader
+ * {
+ * private:
+ *   uint32_t mMagic;
+ *   uint32_t mLength;
+ *   uint32_t mTotalRecords;
+ *   uint64_t mChecksum;

+ *     mMagic = BigEndian::readUint32(ptr); ptr += sizeof(uint32_t);
+ *     mLength = BigEndian::readUint32(ptr); ptr += sizeof(uint32_t);
+ *     mTotalRecords = BigEndian::readUint32(ptr); ptr += sizeof(uint32_t);

+ * Why not just sample every N'th event? This technique is called "systematic
+ * sampling"; it's simple and efficient, and it's fine if we imagine a
+ * patternless stream of events. But what if we're sampling allocations, and the
+ * program happens to have a loop where each iteration does exactly N
+ * allocations? You would end up sampling the same allocation every time through
+ * the loop; the entire rest of the loop becomes invisible to your measurements!
+ * More generally, if each iteration does M allocations, and M and N have any
+ * common divisor at all, most allocation sites will never be sampled. If
+ * they're both even, say, the odd-numbered allocations disappear from your
+ * results.
+ *
+ * Ideally, we'd like each event to have some probability P of being sampled,
+ * independent of its neighbors and of its position in the sequence. This is
+ * called "Bernoulli sampling", and it doesn't suffer from any of the problems
+ * mentioned above.
+ *
+ * One disadvantage of Bernoulli sampling is that you can't be sure exactly how
+ * many samples you'll get: technically, it's possible that you might sample
+ * none of them, or all of them. But if the number of events N is large, these
+ * aren't likely outcomes; you can generally expect somewhere around P * N
+ * events to be sampled.
+ *
+ * The other disadvantage of Bernoulli sampling is that you have to generate a
+ * random number for every event, which can be slow.
+ *
+ * [significant pause]
+ *
+ * BUT NOT WITH THIS CLASS! FastBernoulliTrial lets you do true Bernoulli
+ * sampling, while generating a fresh random number only when we do decide to
+ * sample an event, not on every trial. When it decides not to sample, a call to
+ * |FastBernoulliTrial::trial| is nothing but decrementing a counter and
+ * comparing it to zero. So the lower your sampling probability is, the less
+ * overhead FastBernoulliTrial imposes.
+ *
+ * Probabilities of 0 and 1 are handled efficiently. (In neither case need we
+ * ever generate a random number at all.)
+ *
+ * The essential API:
+ *
+ * - FastBernoulliTrial(double P)
+ *   Construct an instance that selects events with probability P.
+ *
+ * - FastBernoulliTrial::trial()
+ *   Return true with probability P. Call this each time an event occurs, to
+ *   decide whether to sample it or not.
+ *
+ * - FastBernoulliTrial::trial(size_t n)
+ *   Equivalent to calling trial() |n| times, and returning true if any of those
+ *   calls do. However, like trial, this runs in fast constant time.
+ *
+ *   What is this good for? In some applications, some events are "bigger" than
+ *   others. For example, large allocations are more significant than small
+ *   allocations. Perhaps we'd like to imagine that we're drawing allocations
+ *   from a stream of bytes, and performing a separate Bernoulli trial on every
+ *   byte from the stream. We can accomplish this by calling |t.trial(S)| for
+ *   the number of bytes S, and sampling the event if that returns true.
+ *
+ *   Of course, this style of sampling needs to be paired with analysis and
+ *   presentation that makes the size of the event apparent, lest trials with
+ *   large values for |n| appear to be indistinguishable from those with small

+   * This comment should just read, "Generate skip counts with a geometric
+   * distribution", and leave everyone to go look that up and see why it's the
+   * right thing to do, if they don't know already.
+   *
+   * BUT IF YOU'RE CURIOUS, COMMENTS ARE FREE...
+   *
+   * Instead of generating a fresh random number for every trial, we can
+   * randomly generate a count of how many times we should return false before
+   * the next time we return true. We call this a "skip count". Once we've
+   * returned true, we generate a fresh skip count, and begin counting down
+   * again.
+   *
+   * Here's an awesome fact: by exercising a little care in the way we generate
+   * skip counts, we can produce results indistinguishable from those we would
+   * get "rolling the dice" afresh for every trial.
+   *
+   * In short, skip counts in Bernoulli trials of probability P obey a geometric
+   * distribution. If a random variable X is uniformly distributed from [0..1),
+   * then std::floor(std::log(X) / std::log(1-P)) has the appropriate geometric
+   * distribution for the skip counts.
+   *
+   * Why that formula?
+   *
+   * Suppose we're to return |true| with some probability P, say, 0.3. Spread
+   * all possible futures along a line segment of length 1. In portion P of
+   * those cases, we'll return true on the next call to |trial|; the skip count
+   * is 0. For the remaining portion 1-P of cases, the skip count is 1 or more.
+   *
+   * skip:                0                         1 or more
+   *             |------------------^-----------------------------------------|
+   * portion:            0.3                            0.7
+   *                      P                             1-P
+   *
+   * But the "1 or more" section of the line is subdivided the same way: *within
+   * that section*, in portion P the second call to |trial()| returns true, and in
+   * portion 1-P it returns false a second time; the skip count is two or more.
+   * So we return true on the second call in proportion 0.7 * 0.3, and skip at
+   * least the first two in proportion 0.7 * 0.7.
+   *
+   * skip:                0                1              2 or more
+   *             |------------------^------------^----------------------------|
+   * portion:            0.3           0.7 * 0.3          0.7 * 0.7
+   *                      P             (1-P)*P            (1-P)^2
+   *
+   * We can continue to subdivide:
+   *
+   * skip >= 0:  |------------------------------------------------- (1-P)^0 --|
+   * skip >= 1:  |                  ------------------------------- (1-P)^1 --|
+   * skip >= 2:  |                               ------------------ (1-P)^2 --|
+   * skip >= 3:  |                                 ^     ---------- (1-P)^3 --|
+   * skip >= 4:  |                                 .            --- (1-P)^4 --|
+   *                                               .
+   *                                               ^X, see below
+   *
+   * In other words, the likelihood of the next n calls to |trial| returning
+   * false is (1-P)^n. The longer a run we require, the more the likelihood
+   * drops. Further calls may return false too, but this is the probability
+   * we'll skip at least n.
+   *
+   * This is interesting, because we can pick a point along this line segment
+   * and see which skip count's range it falls within; the point X above, for
+   * example, is within the ">= 2" range, but not within the ">= 3" range, so it
+   * designates a skip count of 2. So if we pick points on the line at random
+   * and use the skip counts they fall under, that will be indistinguishable
+   * from generating a fresh random number between 0 and 1 for each trial and
+   * comparing it to P.
+   *
+   * So to find the skip count for a point X, we must ask: To what whole power
+   * must we raise 1-P such that we include X, but the next power would exclude
+   * it? This is exactly std::floor(std::log(X) / std::log(1-P)).
+   *
+   * Our algorithm is then, simply: When constructed, compute an initial skip
+   * count. Return false from |trial| that many times, and then compute a new skip
+   * count.
+   *
+   * For a call to |trial(n)|, if the skip count is greater than n, return false
+   * and subtract n from the skip count. If the skip count is less than n,
+   * return true and compute a new skip count. Since each trial is independent,
+   * it doesn't matter by how much n overshoots the skip count; we can actually
+   * compute a new skip count at *any* time without affecting the distribution.
+   * This is really beautiful.

+       * treat approximation using intervals with open boundaries: saying a

+       * When we use closed boundaries like [2**-53, 1], we're careful to ensure
+       * the boundary values are actually representable.)
+       *
+       * - After the comparison above, we know mProbability is in (0,1).
+       *
+       * - The gaps below 1 are 2**-53, so that interval is (0, 1-2**-53].
+       *
+       * - Because the floating-point gaps near 1 are wider than those near
+       *   zero, there are many small positive doubles ε such that 1-ε rounds to
+       *   exactly 1. However, 2**-53 can be represented exactly. So
+       *   1-mProbability is in [2**-53, 1].
+       *
+       * - log(1 - mProbability) is thus in (-37, 0].
+       *
+       *   That range includes zero, but when we use mInvLogNotProbability, it
+       *   would be helpful if we could trust that it's negative. So when log(1
+       *   - mProbability) is 0, we'll just set mProbability to 0, so that
+       *   mInvLogNotProbability is not used in chooseSkipCount.
+       *
+       * - How much of the range of mProbability does this cause us to ignore?
+       *   The only value for which log returns 0 is exactly 1; the slope of log
+       *   at 1 is 1, so for small ε such that 1 - ε != 1, log(1 - ε) is -ε,
+       *   never 0. The gaps near one are larger than the gaps near zero, so if
+       *   1 - ε wasn't 1, then -ε is representable. So if log(1 - mProbability)

+/*
+ * This file exports functions for hashing data down to a 32-bit value,
+ * including:
+ *
+ *  - HashString    Hash a char* or char16_t/wchar_t* of known or unknown
+ *                  length.
+ *
+ *  - HashBytes     Hash a byte array of known length.
+ *
+ *  - HashGeneric   Hash one or more values.  Currently, we support uint32_t,
+ *                  types which can be implicitly cast to uint32_t, data
+ *                  pointers, and function pointers.
+ *
+ *  - AddToHash     Add one or more values to the given hash.  This supports the
+ *                  same list of types as HashGeneric.
+ *
+ *
+ * You can chain these functions together to hash complex objects.  For example:
+ *
+ *  class ComplexObject
+ *  {
+ *    char* mStr;
+ *    uint32_t mUint1, mUint2;
+ *    void (*mCallbackFn)();
+ *
+ *  public:
+ *    uint32_t hash()
+ *    {
+ *      uint32_t hash = HashString(mStr);
+ *      hash = AddToHash(hash, mUint1, mUint2);
+ *      return AddToHash(hash, mCallbackFn);
+ *    }
+ *  };
+ *
+ * If you want to hash an nsAString or nsACString, use the HashString functions
+ * in nsHashKeys.h.

+ *
+ *   You have a variadic function Foo:

+ *
+ *   And a variadic function Bar, which contains a tuple:

+ *     void Bar() {
+ *       // ...
+ *       Tuple<Args...> t;

+ *
+ *   You want to write:
+ *
+ *     Foo(Get<0>(t), Get<1>(t), ..., Get<N>(t))
+ *
+ *   but you can't literally write that, because N is different for different
+ *   instantiations of Bar.
+ *
+ * Solution:
+ *
+ *   Write a helper function which takes the tuple, and an index sequence

+/* A JSON pretty-printer class. */
+
+// A typical JSON-writing library requires you to first build up a data
+// structure that represents a JSON object and then serialize it (to file, or
+// somewhere else). This approach makes for a clean API, but building the data
+// structure takes up memory. Sometimes that isn't desirable, such as when the
+// JSON data is produced for memory reporting.
+//
+// The JSONWriter class instead allows JSON data to be written out
+// incrementally without building up large data structures.
+//
+// The API is slightly uglier than you would see in a typical JSON-writing
+// library, but still fairly easy to use. It's possible to generate invalid
+// JSON with JSONWriter, but typically the most basic testing will identify any
+// such problems.
+//
+// Similarly, there are no RAII facilities for automatically closing objects
+// and arrays. These would be nice if you are generating all your code within
+// nested functions, but in other cases you'd have to maintain an explicit
+// stack of RAII objects and manually unwind it, which is no better than just
+// calling "end" functions. Furthermore, the consequences of forgetting to
+// close an object or array are obvious and, again, will be identified via
+// basic testing, unlike other cases where RAII is typically used (e.g. smart
+// pointers) and the consequences of defects are more subtle.
+//
+// Importantly, the class does solve the two hard problems of JSON
+// pretty-printing, which are (a) correctly escaping strings, and (b) adding
+// appropriate indentation and commas between items.
+//
+// By default, every property is placed on its own line. However, it is
+// possible to request that objects and arrays be placed entirely on a single
+// line, which can reduce output size significantly in some cases.
+//
+// Strings used (for property names and string property values) are |const
+// char*| throughout, and can be ASCII or UTF-8.
+//
+// EXAMPLE
+// -------
+// Assume that |MyWriteFunc| is a class that implements |JSONWriteFunc|. The
+// following code:
+//
+//   JSONWriter w(MakeUnique<MyWriteFunc>());
+//   w.Start();
+//   {
+//     w.NullProperty("null");
+//     w.BoolProperty("bool", true);
+//     w.IntProperty("int", 1);
+//     w.StartArrayProperty("array");
+//     {
+//       w.StringElement("string");
+//       w.StartObjectElement();
+//       {
+//         w.DoubleProperty("double", 3.4);
+//         w.StartArrayProperty("single-line array", w.SingleLineStyle);
+//         {
+//           w.IntElement(1);
+//           w.StartObjectElement();  // SingleLineStyle is inherited from
+//           w.EndObjectElement();    //   above for this collection
+//         }
+//         w.EndArray();
+//       }
+//       w.EndObjectElement();
+//     }
+//     w.EndArrayProperty();
+//   }
+//   w.End();
+//
+// will produce pretty-printed output for the following JSON object:
+//
+//  {
+//   "null": null,
+//   "bool": true,
+//   "int": 1,
+//   "array": [
+//    "string",
+//    {
+//     "double": 3.4,
+//     "single-line array": [1, {}]
+//    }
+//   ]
+//  }
+//
+// The nesting in the example code is obviously optional, but can aid
+// readability.

+/*
+ * The classes LinkedList<T> and LinkedListElement<T> together form a
+ * convenient, type-safe doubly-linked list implementation.
+ *
+ * The class T which will be inserted into the linked list must inherit from
+ * LinkedListElement<T>.  A given object may be in only one linked list at a
+ * time.
+ *
+ * A LinkedListElement automatically removes itself from the list upon
+ * destruction, and a LinkedList will fatally assert in debug builds if it's
+ * non-empty when it's destructed.
+ *
+ * For example, you might use LinkedList in a simple observer list class as
+ * follows.
+ *
+ *   class Observer : public LinkedListElement<Observer>
+ *   {
+ *   public:
+ *     void observe(char* aTopic) { ... }
+ *   };
+ *
+ *   class ObserverContainer
+ *   {
+ *   private:
+ *     LinkedList<Observer> list;
+ *
+ *   public:
+ *     void addObserver(Observer* aObserver)
+ *     {
+ *       // Will assert if |aObserver| is part of another list.
+ *       list.insertBack(aObserver);
+ *     }
+ *
+ *     void removeObserver(Observer* aObserver)
+ *     {
+ *       // Will assert if |aObserver| is not part of some list.
+ *       aObserver.remove();
+ *       // Or, will assert if |aObserver| is not part of |list| specifically.
+ *       // aObserver.removeFrom(list);
+ *     }
+ *
+ *     void notifyObservers(char* aTopic)
+ *     {
+ *       for (Observer* o = list.getFirst(); o != nullptr; o = o->getNext()) {
+ *         o->observe(aTopic);
+ *       }
+ *     }
+ *   };
+ *
+ * Additionally, the class AutoCleanLinkedList<T> is a LinkedList<T> that will
+ * remove and delete each element still within itself upon destruction. Note
+ * that because each element is deleted, elements must have been allocated
+ * using |new|.

+   * node) and a branch on this value in getNext/getPrevious.
+   *
+   * We could get rid of the extra word of storage by shoving the "is

+   *
+   * But the goal here isn't to win an award for the fastest or slimmest
+   * linked list; rather, we want a *convenient* linked list.  So we won't
+   * waste time guessing which micro-optimization strategy is best.
+   *
+   *
+   * Speaking of unnecessary work, it's worth addressing here why we wrote
+   * mozilla::LinkedList in the first place, instead of using stl::list.
+   *
+   * The key difference between mozilla::LinkedList and stl::list is that
+   * mozilla::LinkedList stores the mPrev/mNext pointers in the object itself,
+   * while stl::list stores the mPrev/mNext pointers in a list element which
+   * itself points to the object being stored.
+   *
+   * mozilla::LinkedList's approach makes it harder to store an object in more
+   * than one list.  But the upside is that you can call next() / prev() /
+   * remove() directly on the object.  With stl::list, you'd need to store a
+   * pointer to its iterator in the object in order to accomplish this.  Not
+   * only would this waste space, but you'd have to remember to update that
+   * pointer every time you added or removed the object from a list.
+   *
+   * In-place, constant-time removal is a killer feature of doubly-linked
+   * lists, and supporting this painlessly was a key design criterion.

+ * Maybe is a container class which contains either zero or one elements. It
+ * serves two roles. It can represent values which are *semantically* optional,
+ * augmenting a type with an explicit 'Nothing' value. In this role, it provides
+ * methods that make it easy to work with values that may be missing, along with
+ * equality and comparison operators so that Maybe values can be stored in
+ * containers. Maybe values can be constructed conveniently in expressions using
+ * type inference, as follows:
+ *
+ *   void doSomething(Maybe<Foo> aFoo) {
+ *     if (aFoo)                  // Make sure that aFoo contains a value...
+ *       aFoo->takeAction();      // and then use |aFoo->| to access it.
+ *   }                            // |*aFoo| also works!
+ *
+ *   doSomething(Nothing());      // Passes a Maybe<Foo> containing no value.
+ *   doSomething(Some(Foo(100))); // Passes a Maybe<Foo> containing |Foo(100)|.
+ *
+ * You'll note that it's important to check whether a Maybe contains a value
+ * before using it, using conversion to bool, |isSome()|, or |isNothing()|. You
+ * can avoid these checks, and sometimes write more readable code, using
+ * |valueOr()|, |ptrOr()|, and |refOr()|, which allow you to retrieve the value
+ * in the Maybe and provide a default for the 'Nothing' case.  You can also use
+ * |apply()| to call a function only if the Maybe holds a value, and |map()| to
+ * transform the value in the Maybe, returning another Maybe with a possibly
+ * different type.
+ *
+ * Maybe's other role is to support lazily constructing objects without using
+ * dynamic storage. A Maybe directly contains storage for a value, but it's
+ * empty by default. |emplace()|, as mentioned above, can be used to construct a
+ * value in Maybe's storage.  The value a Maybe contains can be destroyed by
+ * calling |reset()|; this will happen automatically if a Maybe is destroyed
+ * while holding a value.
+ *
+ * It's a common idiom in C++ to use a pointer as a 'Maybe' type, with a null
+ * value meaning 'Nothing' and any other value meaning 'Some'. You can convert
+ * from such a pointer to a Maybe value using 'ToMaybe()'.
+ *
+ * Maybe is inspired by similar types in the standard library of many other
+ * languages (e.g. Haskell's Maybe and Rust's Option). In the C++ world it's
+ * very similar to std::optional, which was proposed for C++14 and originated in
+ * Boost. The most important differences between Maybe and std::optional are:
+ *
+ *   - std::optional<T> may be compared with T. We deliberately forbid that.
+ *   - std::optional allows in-place construction without a separate call to
+ *     |emplace()| by using a dummy |in_place_t| value to tag the appropriate
+ *     constructor.
+ *   - std::optional has |valueOr()|, equivalent to Maybe's |valueOr()|, but
+ *     lacks corresponding methods for |refOr()| and |ptrOr()|.
+ *   - std::optional lacks |map()| and |apply()|, making it less suitable for
+ *     functional-style code.
+ *   - std::optional lacks many convenience functions that Maybe has. Most
+ *     unfortunately, it lacks equivalents of the type-inferred constructor
+ *     functions |Some()| and |Nothing()|.
+ *
+ * N.B. GCC has missed optimizations with Maybe in the past and may generate
+ * extra branches/loads/stores. Use with caution on hot paths; it's not known
+ * whether or not this is still a problem.

+/*
+ * "Move" References
+ *
+ * Some types can be copied much more efficiently if we know the original's
+ * value need not be preserved --- that is, if we are doing a "move", not a
+ * "copy". For example, if we have:
+ *
+ *   Vector<T> u;
+ *   Vector<T> v(u);
+ *
+ * the constructor for v must apply a copy constructor to each element of u ---
+ * taking time linear in the length of u. However, if we know we will not need u
+ * any more once v has been initialized, then we could initialize v very
+ * efficiently simply by stealing u's dynamically allocated buffer and giving it
+ * to v --- a constant-time operation, regardless of the size of u.
+ *
+ * Moves often appear in container implementations. For example, when we append
+ * to a vector, we may need to resize its buffer. This entails moving each of
+ * its extant elements from the old, smaller buffer to the new, larger buffer.
+ * But once the elements have been migrated, we're just going to throw away the
+ * old buffer; we don't care if they still have their values. So if the vector's
+ * element type can implement "move" more efficiently than "copy", the vector
+ * resizing should by all means use a "move" operation. Hash tables should also
+ * use moves when resizing their internal array as entries are added and
+ * removed.
+ *
+ * The details of the optimization, and whether it's worth applying, vary
+ * from one type to the next: copying an 'int' is as cheap as moving it, so
+ * there's no benefit in distinguishing 'int' moves from copies. And while
+ * some constructor calls for complex types are moves, many really have to
+ * be copies, and can't be optimized this way. So we need:
+ *
+ * 1) a way for a type (like Vector) to announce that it can be moved more
+ *    efficiently than it can be copied, and provide an implementation of that
+ *    move operation; and
+ *
+ * 2) a way for a particular invocation of a copy constructor to say that it's
+ *    really a move, not a copy, and that the value of the original isn't
+ *    important afterwards (although it must still be safe to destroy).
+ *
+ * If a constructor has a single argument of type 'T&&' (an 'rvalue reference
+ * to T'), that indicates that it is a 'move constructor'. That's 1). It should
+ * move, not copy, its argument into the object being constructed. It may leave
+ * the original in any safely-destructible state.
+ *
+ * If a constructor's argument is an rvalue, as in 'C(f(x))' or 'C(x + y)', as
+ * opposed to an lvalue, as in 'C(x)', then overload resolution will prefer the
+ * move constructor, if there is one. The 'mozilla::Move' function, defined in
+ * this file, is an identity function you can use in a constructor invocation to
+ * make any argument into an rvalue, like this: C(Move(x)). That's 2). (You
+ * could use any function that works, but 'Move' indicates your intention
+ * clearly.)
+ *
+ * Where we might define a copy constructor for a class C like this:
+ *
+ *   C(const C& rhs) { ... copy rhs to this ... }
+ *
+ * we would declare a move constructor like this:
+ *
+ *   C(C&& rhs) { .. move rhs to this ... }
+ *
+ * And where we might perform a copy like this:
+ *
+ *   C c2(c1);
+ *
+ * we would perform a move like this:
+ *
+ *   C c2(Move(c1));
+ *
+ * Note that 'T&&' implicitly converts to 'T&'. So you can pass a 'T&&' to an
+ * ordinary copy constructor for a type that doesn't support a special move
+ * constructor, and you'll just get a copy. This means that templates can use
+ * Move whenever they know they won't use the original value any more, even if
+ * they're not sure whether the type at hand has a specialized move constructor.
+ * If it doesn't, the 'T&&' will just convert to a 'T&', and the ordinary copy
+ * constructor will apply.
+ *
+ * A class with a move constructor can also provide a move assignment operator.
+ * A generic definition would run this's destructor, and then apply the move
+ * constructor to *this's memory. A typical definition:
+ *
+ *   C& operator=(C&& rhs) {
+ *     MOZ_ASSERT(&rhs != this, "self-moves are prohibited");
+ *     this->~C();
+ *     new(this) C(Move(rhs));
+ *     return *this;
+ *   }
+ *
+ * With that in place, one can write move assignments like this:
+ *
+ *   c2 = Move(c1);
+ *
+ * This destroys c2, moves c1's value to c2, and leaves c1 in an undefined but
+ * destructible state.
+ *
+ * As we say, a move must leave the original in a "destructible" state. The
+ * original's destructor will still be called, so if a move doesn't
+ * actually steal all its resources, that's fine. We require only that the
+ * move destination must take on the original's value; and that destructing
+ * the original must not break the move destination.
+ *
+ * (Opinions differ on whether move assignment operators should deal with move
+ * assignment of an object onto itself. It seems wise to either handle that
+ * case, or assert that it does not occur.)
+ *
+ * Forwarding:
+ *
+ * Sometimes we want copy construction or assignment if we're passed an ordinary
+ * value, but move construction if passed an rvalue reference. For example, if
+ * our constructor takes two arguments and either could usefully be a move, it
+ * seems silly to write out all four combinations:
+ *
+ *   C::C(X&  x, Y&  y) : x(x),       y(y)       { }
+ *   C::C(X&  x, Y&& y) : x(x),       y(Move(y)) { }
+ *   C::C(X&& x, Y&  y) : x(Move(x)), y(y)       { }
+ *   C::C(X&& x, Y&& y) : x(Move(x)), y(Move(y)) { }
+ *
+ * To avoid this, C++11 has tweaks to make it possible to write what you mean.
+ * The four constructor overloads above can be written as one constructor
+ * template like so[0]:
+ *
+ *   template <typename XArg, typename YArg>
+ *   C::C(XArg&& x, YArg&& y) : x(Forward<XArg>(x)), y(Forward<YArg>(y)) { }
+ *
+ * ("'Don't Repeat Yourself'? What's that?")
+ *
+ * This takes advantage of two new rules in C++11:
+ *
+ * - First, when a function template takes an argument that is an rvalue
+ *   reference to a template argument (like 'XArg&& x' and 'YArg&& y' above),
+ *   then when the argument is applied to an lvalue, the template argument
+ *   resolves to 'T&'; and when it is applied to an rvalue, the template
+ *   argument resolves to 'T'. Thus, in a call to C::C like:
+ *
+ *      X foo(int);
+ *      Y yy;
+ *
+ *      C(foo(5), yy)
+ *
+ *   XArg would resolve to 'X', and YArg would resolve to 'Y&'.
+ *
+ * - Second, Whereas C++ used to forbid references to references, C++11 defines
+ *   'collapsing rules': 'T& &', 'T&& &', and 'T& &&' (that is, any combination
+ *   involving an lvalue reference) now collapse to simply 'T&'; and 'T&& &&'
+ *   collapses to 'T&&'.
+ *
+ *   Thus, in the call above, 'XArg&&' is 'X&&'; and 'YArg&&' is 'Y& &&', which
+ *   collapses to 'Y&'. Because the arguments are declared as rvalue references
+ *   to template arguments, the lvalue-ness "shines through" where present.
+ *
+ * Then, the 'Forward<T>' function --- you must invoke 'Forward' with its type
+ * argument --- returns an lvalue reference or an rvalue reference to its
+ * argument, depending on what T is. In our unified constructor definition, that
+ * means that we'll invoke either the copy or move constructors for x and y,
+ * depending on what we gave C's constructor. In our call, we'll move 'foo()'
+ * into 'x', but copy 'yy' into 'y'.
+ *
+ * This header file defines Move and Forward in the mozilla namespace. It's up
+ * to individual containers to annotate moves as such, by calling Move; and it's
+ * up to individual types to define move constructors and assignment operators
+ * when valuable.
+ *
+ * (C++11 says that the <utility> header file should define 'std::move' and
+ * 'std::forward', which are just like our 'Move' and 'Forward'; but those
+ * definitions aren't available in that header on all our platforms, so we
+ * define them ourselves here.)
+ *
+ * 0. This pattern is known as "perfect forwarding".  Interestingly, it is not
+ *    actually perfect, and it can't forward all possible argument expressions!
+ *    There is a C++11 issue: you can't form a reference to a bit-field.  As a
+ *    workaround, assign the bit-field to a local variable and use that:
+ *
+ *      // C is as above
+ *      struct S { int x : 1; } s;
+ *      C(s.x, 0); // BAD: s.x is a reference to a bit-field, can't form those
+ *      int tmp = s.x;
+ *      C(tmp, 0); // OK: tmp not a bit-field

+// It's often unclear if a particular pointer, be it raw (T*) or smart
+// (RefPtr<T>, nsCOMPtr<T>, etc.) can be null. This leads to missing null
+// checks (which can cause crashes) and unnecessary null checks (which clutter
+// the code).
+//
+// C++ has a built-in alternative that avoids these problems: references. This
+// module defines another alternative, NotNull, which can be used in cases
+// where references are not suitable.
+//
+// In the comments below we use the word "handle" to cover all varieties of
+// pointers and references.
+//
+// References
+// ----------
+// References are always non-null. (You can do |T& r = *p;| where |p| is null,
+// but that's undefined behaviour. C++ doesn't provide any built-in, ironclad
+// guarantee of non-nullness.)
+//
+// A reference works well when you need a temporary handle to an existing
+// single object, e.g. for passing a handle to a function, or as a local handle
+// within another object. (In Rust parlance, this is a "borrow".)
+//
+// A reference is less appropriate in the following cases.
+//
+// - As a primary handle to an object. E.g. code such as this is possible but
+//   strange: |T& t = *new T(); ...; delete &t;|
+//
+// - As a handle to an array. It's common for |T*| to refer to either a single
+//   |T| or an array of |T|, but |T&| cannot refer to an array of |T| because
+//   you can't index off a reference (at least, not without first converting it
+//   to a pointer).
+//
+// - When the handle identity is meaningful, e.g. if you have a hashtable of
+//   handles, because you have to use |&| on the reference to convert it to a
+//   pointer.
+//
+// - Some people don't like using non-const references as function parameters,
+//   because it is not clear at the call site that the argument might be
+//   modified.
+//
+// - When you need "smart" behaviour. E.g. we lack reference equivalents to
+//   RefPtr and nsCOMPtr.
+//
+// - When interfacing with code that uses pointers a lot, sometimes using a
+//   reference just feels like an odd fit.
+//
+// Furthermore, a reference is impossible in the following cases.
+//
+// - When the handle is rebound to another object. References don't allow this.
+//
+// - When the handle has type |void|. |void&| is not allowed.
+//
+// NotNull is an alternative that can be used in any of the above cases except
+// for the last one, where the handle type is |void|. See below.
+
+#include "mozilla/Assertions.h"

+// NotNull can be used to wrap a "base" pointer (raw or smart) to indicate it
+// is not null. Some examples:
+//
+// - NotNull<char*>
+// - NotNull<RefPtr<Event>>
+// - NotNull<nsCOMPtr<Event>>
+//
+// NotNull has the following notable properties.
+//
+// - It has zero space overhead.
+//
+// - It must be initialized explicitly. There is no default initialization.
+//
+// - It auto-converts to the base pointer type.
+//
+// - It does not auto-convert from a base pointer. Implicit conversion from a
+//   less-constrained type (e.g. T*) to a more-constrained type (e.g.
+//   NotNull<T*>) is dangerous. Creation and assignment from a base pointer can
+//   only be done with WrapNotNull(), which makes them impossible to overlook,
+//   both when writing and reading code.
+//
+// - When initialized (or assigned) it is checked, and if it is null we abort.
+//   This guarantees that it cannot be null.
+//
+// - |operator bool()| is deleted. This means you cannot check a NotNull in a
+//   boolean context, which eliminates the possibility of unnecessary null
+//   checks.

+ *
+ * ScopeExit is a mechanism to simplify this pattern by keeping an RAII guard

+ * - if |release()| has not been called, the cleanup is always performed at

+/**
+ * UniquePtr is a smart pointer that wholly owns a resource.  Ownership may be
+ * transferred out of a UniquePtr through explicit action, but otherwise the
+ * resource is destroyed when the UniquePtr is destroyed.
+ *
+ * UniquePtr is similar to C++98's std::auto_ptr, but it improves upon auto_ptr
+ * in one crucial way: it's impossible to copy a UniquePtr.  Copying an auto_ptr
+ * obviously *can't* copy ownership of its singly-owned resource.  So what
+ * happens if you try to copy one?  Bizarrely, ownership is implicitly
+ * *transferred*, preserving single ownership but breaking code that assumes a
+ * copy of an object is identical to the original.  (This is why auto_ptr is
+ * prohibited in STL containers.)
+ *
+ * UniquePtr solves this problem by being *movable* rather than copyable.
+ * Instead of passing a |UniquePtr u| directly to the constructor or assignment
+ * operator, you pass |Move(u)|.  In doing so you indicate that you're *moving*
+ * ownership out of |u|, into the target of the construction/assignment.  After
+ * the transfer completes, |u| contains |nullptr| and may be safely destroyed.
+ * This preserves single ownership but also allows UniquePtr to be moved by
+ * algorithms that have been made move-safe.  (Note: if |u| is instead a
+ * temporary expression, don't use |Move()|: just pass the expression, because
+ * it's already move-ready.  For more information see Move.h.)
+ *
+ * UniquePtr is also better than std::auto_ptr in that the deletion operation is
+ * customizable.  An optional second template parameter specifies a class that
+ * (through its operator()(T*)) implements the desired deletion policy.  If no
+ * policy is specified, mozilla::DefaultDelete<T> is used -- which will either
+ * |delete| or |delete[]| the resource, depending whether the resource is an
+ * array.  Custom deletion policies ideally should be empty classes (no member
+ * fields, no member fields in base classes, no virtual methods/inheritance),
+ * because then UniquePtr can be just as efficient as a raw pointer.
+ *
+ * Use of UniquePtr proceeds like so:
+ *
+ *   UniquePtr<int> g1; // initializes to nullptr
+ *   g1.reset(new int); // switch resources using reset()
+ *   g1 = nullptr; // clears g1, deletes the int
+ *
+ *   UniquePtr<int> g2(new int); // owns that int
+ *   int* p = g2.release(); // g2 leaks its int -- still requires deletion
+ *   delete p; // now freed
+ *
+ *   struct S { int x; S(int x) : x(x) {} };
+ *   UniquePtr<S> g3, g4(new S(5));
+ *   g3 = Move(g4); // g3 owns the S, g4 cleared
+ *   S* p = g3.get(); // g3 still owns |p|
+ *   assert(g3->x == 5); // operator-> works (if .get() != nullptr)
+ *   assert((*g3).x == 5); // also operator* (again, if not cleared)
+ *   Swap(g3, g4); // g4 now owns the S, g3 cleared
+ *   g3.swap(g4);  // g3 now owns the S, g4 cleared
+ *   UniquePtr<S> g5(Move(g3)); // g5 owns the S, g3 cleared
+ *   g5.reset(); // deletes the S, g5 cleared
+ *
+ *   struct FreePolicy { void operator()(void* p) { free(p); } };
+ *   UniquePtr<int, FreePolicy> g6(static_cast<int*>(malloc(sizeof(int))));
+ *   int* ptr = g6.get();
+ *   g6 = nullptr; // calls free(ptr)
+ *
+ * Now, carefully note a few things you *can't* do:
+ *
+ *   UniquePtr<int> b1;
+ *   b1 = new int; // BAD: can only assign another UniquePtr
+ *   int* ptr = b1; // BAD: no auto-conversion to pointer, use get()
+ *
+ *   UniquePtr<int> b2(b1); // BAD: can't copy a UniquePtr
+ *   UniquePtr<int> b3 = b1; // BAD: can't copy-assign a UniquePtr
+ *
+ * (Note that changing a UniquePtr to store a direct |new| expression is
+ * permitted, but usually you should use MakeUnique, defined at the end of this
+ * header.)
+ *
+ * A few miscellaneous notes:
+ *
+ * UniquePtr, when not instantiated for an array type, can be move-constructed
+ * and move-assigned, not only from itself but from "derived" UniquePtr<U, E>
+ * instantiations where U converts to T and E converts to D.  If you want to use
+ * this, you're going to have to specify a deletion policy for both UniquePtr
+ * instantations, and T pretty much has to have a virtual destructor.  In other
+ * words, this doesn't work:
+ *
+ *   struct Base { virtual ~Base() {} };
+ *   struct Derived : Base {};
+ *
+ *   UniquePtr<Base> b1;
+ *   // BAD: DefaultDelete<Base> and DefaultDelete<Derived> don't interconvert
+ *   UniquePtr<Derived> d1(Move(b));
+ *
+ *   UniquePtr<Base> b2;
+ *   UniquePtr<Derived, DefaultDelete<Base>> d2(Move(b2)); // okay
+ *
+ * UniquePtr is specialized for array types.  Specializing with an array type
+ * creates a smart-pointer version of that array -- not a pointer to such an
+ * array.
+ *
+ *   UniquePtr<int[]> arr(new int[5]);
+ *   arr[0] = 4;
+ *
+ * What else is different?  Deletion of course uses |delete[]|.  An operator[]
+ * is provided.  Functionality that doesn't make sense for arrays is removed.
+ * The constructors and mutating methods only accept array pointers (not T*, U*
+ * that converts to T*, or UniquePtr<U[]> or UniquePtr<U>) or |nullptr|.
+ *
+ * It's perfectly okay for a function to return a UniquePtr. This transfers
+ * the UniquePtr's sole ownership of the data, to the fresh UniquePtr created
+ * in the calling function, that will then solely own that data. Such functions
+ * can return a local variable UniquePtr, |nullptr|, |UniquePtr(ptr)| where
+ * |ptr| is a |T*|, or a UniquePtr |Move()|'d from elsewhere.
+ *
+ * UniquePtr will commonly be a member of a class, with lifetime equivalent to
+ * that of that class.  If you want to expose the related resource, you could
+ * expose a raw pointer via |get()|, but ownership of a raw pointer is
+ * inherently unclear.  So it's better to expose a |const UniquePtr&| instead.
+ * This prohibits mutation but still allows use of |get()| when needed (but
+ * operator-> is preferred).  Of course, you can only use this smart pointer as
+ * long as the enclosing class instance remains live -- no different than if you
+ * exposed the |get()| raw pointer.
+ *
+ * To pass a UniquePtr-managed resource as a pointer, use a |const UniquePtr&|
+ * argument.  To specify an inout parameter (where the method may or may not
+ * take ownership of the resource, or reset it), or to specify an out parameter
+ * (where simply returning a |UniquePtr| isn't possible), use a |UniquePtr&|
+ * argument.  To unconditionally transfer ownership of a UniquePtr
+ * into a method, use a |UniquePtr| argument.  To conditionally transfer
+ * ownership of a resource into a method, should the method want it, use a
+ * |UniquePtr&&| argument.

+ * MakeUnique is a helper function for allocating new'd objects and arrays,
+ * returning a UniquePtr containing the resulting pointer.  The semantics of
+ * MakeUnique<Type>(...) are as follows.
+ *
+ *   If Type is an array T[n]:
+ *     Disallowed, deleted, no overload for you!
+ *   If Type is an array T[]:
+ *     MakeUnique<T[]>(size_t) is the only valid overload.  The pointer returned
+ *     is as if by |new T[n]()|, which value-initializes each element.  (If T
+ *     isn't a class type, this will zero each element.  If T is a class type,
+ *     then roughly speaking, each element will be constructed using its default
+ *     constructor.  See C++11 [dcl.init]p7 for the full gory details.)
+ *   If Type is non-array T:
+ *     The arguments passed to MakeUnique<T>(...) are forwarded into a
+ *     |new T(...)| call, initializing the T as would happen if executing
+ *     |T(...)|.
+ *
+ * There are various benefits to using MakeUnique instead of |new| expressions.
+ *
+ * First, MakeUnique eliminates use of |new| from code entirely.  If objects are
+ * only created through UniquePtr, then (assuming all explicit release() calls
+ * are safe, including transitively, and no type-safety casting funniness)
+ * correctly maintained ownership of the UniquePtr guarantees no leaks are
+ * possible.  (This pays off best if a class is only ever created through a
+ * factory method on the class, using a private constructor.)
+ *
+ * Second, initializing a UniquePtr using a |new| expression requires repeating
+ * the name of the new'd type, whereas MakeUnique in concert with the |auto|
+ * keyword names it only once:
+ *
+ *   UniquePtr<char> ptr1(new char()); // repetitive
+ *   auto ptr2 = MakeUnique<char>();   // shorter
+ *
+ * Of course this assumes the reader understands the operation MakeUnique
+ * performs.  In the long run this is probably a reasonable assumption.  In the
+ * short run you'll have to use your judgment about what readers can be expected
+ * to know, or to quickly look up.
+ *
+ * Third, a call to MakeUnique can be assigned directly to a UniquePtr.  In
+ * contrast you can't assign a pointer into a UniquePtr without using the
+ * cumbersome reset().
+ *
+ *   UniquePtr<char> p;
+ *   p = new char;           // ERROR
+ *   p.reset(new char);      // works, but fugly
+ *   p = MakeUnique<char>(); // preferred
+ *
+ * (And third, although not relevant to Mozilla: MakeUnique is exception-safe.
+ * An exception thrown after |new T| succeeds will leak that memory, unless the
+ * pointer is assigned to an object that will manage its ownership.  UniquePtr
+ * ably serves this function.)

+/**
+ * # mozilla::Variant
+ *
+ * A variant / tagged union / heterogenous disjoint union / sum-type template
+ * class. Similar in concept to (but not derived from) `boost::variant`.
+ *
+ * Sometimes, you may wish to use a C union with non-POD types. However, this is
+ * forbidden in C++ because it is not clear which type in the union should have
+ * its constructor and destructor run on creation and deletion
+ * respectively. This is the problem that `mozilla::Variant` solves.
+ *
+ * ## Usage
+ *
+ * A `mozilla::Variant` instance is constructed (via move or copy) from one of
+ * its variant types (ignoring const and references). It does *not* support
+ * construction from subclasses of variant types or types that coerce to one of
+ * the variant types.
+ *
+ *     Variant<char, uint32_t> v1('a');
+ *     Variant<UniquePtr<A>, B, C> v2(MakeUnique<A>());
+ *
+ * Because specifying the full type of a Variant value is often verbose,
+ * AsVariant() can be used to construct a Variant value using type inference in
+ * contexts such as expressions or when returning values from functions. Because
+ * AsVariant() must copy or move the value into a temporary and this cannot
+ * necessarily be elided by the compiler, it's mostly appropriate only for use
+ * with primitive or very small types.
+ *
+ *
+ *     Variant<char, uint32_t> Foo() { return AsVariant('x'); }
+ *     // ...
+ *     Variant<char, uint32_t> v1 = Foo();  // v1 holds char('x').
+ *
+ * All access to the contained value goes through type-safe accessors.
+ *
+ *     void
+ *     Foo(Variant<A, B, C> v)
+ *     {
+ *       if (v.is<A>()) {
+ *         A& ref = v.as<A>();
+ *         ...
+ *       } else {
+ *         ...
+ *       }
+ *     }
+ *
+ * Attempting to use the contained value as type `T1` when the `Variant`
+ * instance contains a value of type `T2` causes an assertion failure.
+ *
+ *     A a;
+ *     Variant<A, B, C> v(a);
+ *     v.as<B>(); // <--- Assertion failure!
+ *
+ * Trying to use a `Variant<Ts...>` instance as some type `U` that is not a
+ * member of the set of `Ts...` is a compiler error.
+ *
+ *     A a;
+ *     Variant<A, B, C> v(a);
+ *     v.as<SomeRandomType>(); // <--- Compiler error!
+ *
+ * Additionally, you can turn a `Variant` that `is<T>` into a `T` by moving it
+ * out of the containing `Variant` instance with the `extract<T>` method:
+ *
+ *     Variant<UniquePtr<A>, B, C> v(MakeUnique<A>());
+ *     auto ptr = v.extract<UniquePtr<A>>();
+ *
+ * Finally, you can exhaustively match on the contained variant and branch into
+ * different code paths depending which type is contained. This is preferred to
+ * manually checking every variant type T with is<T>() because it provides
+ * compile-time checking that you handled every type, rather than runtime
+ * assertion failures.
+ *
+ *     // Bad!
+ *     char* foo(Variant<A, B, C, D>& v) {
+ *       if (v.is<A>()) {
+ *         return ...;
+ *       } else if (v.is<B>()) {
+ *         return ...;
+ *       } else {
+ *         return doSomething(v.as<C>()); // Forgot about case D!
+ *       }
+ *     }
+ *
+ *     // Good!
+ *     struct FooMatcher
+ *     {
+ *       // The return type of all matchers must be identical.
+ *       char* match(A& a) { ... }
+ *       char* match(B& b) { ... }
+ *       char* match(C& c) { ... }
+ *       char* match(D& d) { ... } // Compile-time error to forget D!
+ *     }
+ *     char* foo(Variant<A, B, C, D>& v) {
+ *       return v.match(FooMatcher());
+ *     }
+ *
+ * ## Examples
+ *
+ * A tree is either an empty leaf, or a node with a value and two children:
+ *
+ *     struct Leaf { };
+ *
+ *     template<typename T>
+ *     struct Node
+ *     {
+ *       T value;
+ *       Tree<T>* left;
+ *       Tree<T>* right;
+ *     };
+ *
+ *     template<typename T>
+ *     using Tree = Variant<Leaf, Node<T>>;
+ *
+ * A copy-on-write string is either a non-owning reference to some existing
+ * string, or an owning reference to our copy:
+ *
+ *     class CopyOnWriteString
+ *     {
+ *       Variant<const char*, UniquePtr<char[]>> string;
+ *
+ *       ...

+/**
+ * SupportsWeakPtr lets you have a pointer to an object 'Foo' without affecting
+ * its lifetime. It works by creating a single shared reference counted object
+ * (WeakReference) that each WeakPtr will access 'Foo' through. This lets 'Foo'
+ * clear the pointer in the WeakReference without having to know about all of
+ * the WeakPtrs to it and allows the WeakReference to live beyond the lifetime
+ * of 'Foo'.
+ *
+ * PLEASE NOTE: This weak pointer implementation is not thread-safe.
+ *
+ * Note that when deriving from SupportsWeakPtr you should add
+ * MOZ_DECLARE_WEAKREFERENCE_TYPENAME(ClassName) to the public section of your
+ * class, where ClassName is the name of your class.
+ *
+ * The overhead of WeakPtr is that accesses to 'Foo' becomes an additional
+ * dereference, and an additional heap allocated pointer sized object shared
+ * between all of the WeakPtrs.
+ *
+ * Example of usage:
+ *
+ *   // To have a class C support weak pointers, inherit from
+ *   // SupportsWeakPtr<C>.
+ *   class C : public SupportsWeakPtr<C>
+ *   {
+ *   public:
+ *     MOZ_DECLARE_WEAKREFERENCE_TYPENAME(C)
+ *     int mNum;
+ *     void act();
+ *   };
+ *
+ *   C* ptr = new C();
+ *
+ *   // Get weak pointers to ptr. The first time a weak pointer
+ *   // is obtained, a reference counted WeakReference object is created that
+ *   // can live beyond the lifetime of 'ptr'. The WeakReference
+ *   // object will be notified of 'ptr's destruction.
+ *   WeakPtr<C> weak = ptr;
+ *   WeakPtr<C> other = ptr;
+ *
+ *   // Test a weak pointer for validity before using it.
+ *   if (weak) {
+ *     weak->mNum = 17;
+ *     weak->act();
+ *   }
+ *
+ *   // Destroying the underlying object clears weak pointers to it.
+ *   delete ptr;
+ *
+ *   MOZ_ASSERT(!weak, "Deleting |ptr| clears weak pointers to it.");
+ *   MOZ_ASSERT(!other, "Deleting |ptr| clears all weak pointers to it.");
+ *
+ * WeakPtr is typesafe and may be used with any class. It is not required that
+ * the class be reference-counted or allocated in any particular way.
+ *
+ * The API was loosely inspired by Chromium's weak_ptr.h:
+ * http://src.chromium.org/svn/trunk/src/base/memory/weak_ptr.h
