These methods return an addrefed raw pointer, which makes them easy to use in
ways that cause leaks. If they're to continue returning an addrefed pointer,
they should explicitly return an already_AddRefed.
This also switches to StaticRefPtr with ClearOnShutdown for the cached
pointers for the sake of sanity.

NS_GetWeakReference, called from do_GetWeakReference, QI's its argument
to nsISupportsWeakReference to determine whether a weak reference can be
obtained. If NS_GetWeakReference is already receiving a
nsISupportsWeakReference pointer, or something than can be converted to
one, then we can skip the QI for a small performance win.
QIing to CC interfaces shows up in Speedometer profiles for a few
classes. Presumably there are many of these objects being created and
destroyed. By making these classes check first for the CC interfaces
directly, rather than going up the inheritance chain, this overhead
should be reduced.

The virtual call to this method shows up in profiles, and therefore
would be nice to avoid if possible. We can do that by making
nsIWeakReference hold the weak reference itself and therefore
implementing a non-virtual QueryReferent method.
nsQueryReferent is defined as an nsCOMPtr_helper, which implies that
calling its operator() method requires a virtual call. While
nsQueryReferent is marked `final`, compiler inlining decisions make it
impossible to de-virtualize the call to operator(). However, we have
many other classes returned by do_* functions that nsCOMPtr handles
directly, requiring no extra virtual calls, and we can give
nsQueryReferent the same treatment.
We should not be declaring forward declarations for nsString classes directly,
instead we should use nsStringFwd.h. This will make changing the underlying
types easier.

MozStackWalk() is different on Windows to the other platforms. It has two extra
arguments, which can be used to walk the stack of a different thread.
This patch makes those differences clearer. Instead of having a single function
and forbidding those two arguments on non-Windows, it removes those arguments
from MozStackWalk, and splits off MozStackWalkThread() which retains them. This
also allows those arguments to have more appropriate types (HANDLE instead of
uintptr_t; CONTEXT* instead of than void*) and names (aContext instead of
aPlatformData).
The patch also removes unnecessary reinterpret_casts for the aClosure argument
at a couple of MozStackWalk() callsites.

All the SizeOf{In,Ex}cludingThis() functions take a MallocSizeOf function
which measures memory blocks. This patch introduces a new type, SizeOfState,
which includes a MallocSizeOf function *and* a table of already-measured
pointers, called SeenPtrs. This gives us a general mechanism to measure
graph-like data structures, by recording which nodes have already been
measured. (This approach is used in a number of existing reporters, but not in
a uniform fashion.)
The patch also converts the window memory reporting to use SizeOfState in a lot
of places, all the way through to the measurement of Elements. This is a
precursor for bug 1383977 which will measure Stylo elements, which involve
Arcs.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

mozilla::EditorBase stores nsISelectionController and nsIDocument with nsWeakPtr. However, nsWeakPtr requires QI to retrieve actual pointer and it makes some damage to the performance. If mozilla::WeakPter were available for them, it'd be great. However, it's not available with nsISelectionController nor nsIDocument because it's possible to implement SupportsWeakPtr only with their subclasses but the subclasses shouldn't be referred by editor. Therefore, this patch creates mozilla::CachedWeakPtr<class T> which stores both raw pointer (as cache) and nsWeakPtr and when its cache is requested, it checks if the object referred by nsWeakPtr is still alive.
Additionally, this patch hides the members from subclasses of EditorBase for reducing the maintenance cost.

Once the |aPayload| argument to profile_add_marker() became a UniquePtr the
default value of nullptr caused compilation difficulties that could only be
fixed by #including ProfilerMarkerPayload.h into lots of additional places

When we just had CycleCollectedJSContext (and no CycleCollectedJSRuntime) a
weird thing happened at shutdown:
1. We would call JS_DestroyContext from ~CycleCollectedJSContext. By that time,
the ~XPCJSContext destructor had already finished.
2. Destroying the context runs a final GC. That GC would call back into various
GC callbacks, such as TraceBlackJS and TraceGrayJS.
3. These callbacks would do a virtual method call:
http://searchfox.org/mozilla-central/rev/876c7dd30586f9c6f9c99ef7444f2d73c7acfe7c/xpcom/base/CycleCollectedJSRuntime.cpp#791
4. Normally this method call would call into
XPCContext::TraceNativeBlackRoots. However, C++ changes the vtable for an
object during destruction. So we would only call CycleCollectedJSContext's
version of TraceNativeBlackRoots, which is empty. So we never traced anything.
When I moved this code into the runtime, we actually do call into
XPCJSRuntime::TraceNativeBlackRoots at that time. So the behavior changed, and
that was causing crashes once I nulled out the TLS as you asked. So I removed
these callbacks for the last GC.

It's a very general mechanism for replacing the implementation of
printf_stderr().
It's primarily used by the profiler, sparingly, and not in an important way.
Worse, it prevents us from using MOZ_LOG in the profiler, which is something I
want. Because if any code that locks gPSMutex also calls MOZ_LOG, that then
calls printf_stderr(), which calls profiler_log(), which locks gPSMutex, which
deadlocks.
The only other use of set_stderr_callback() is for the ultra-hacky,
for-local-use-only copy_stderr_to_file() function, which was added for B2G
debugging and is no longer necessary.
