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 main purpose of defining this is to make conversion of places that
use the non-CC variant easier. There are many more places that could
be converted to use these new macros, if somebody felt motivated.

We now have jemalloc_ptr_info() and moz_malloc_enclosing_size_of(), which can
be used to measure heap blocks via interior pointers. This patch does the
following.
- Adds MOZ_DEFINE_MALLOC_ENCLOSING_SIZE_OF, for defining
measure-via-interior-pointer functions.
- Uses these functions to replace some horrid pointer arithmetic in functions
measuring Rust types.

Also adds a mozilla/ResultExtensions.h header to define the appropriate
conversion functions for nsresult and PRResult. This is in a separate header
since those types are not available in Spidermonkey, and this is the pattern
other *Extensions.h headers follow.
Also removes equivalent NS_TRY macros and WrapNSResult inlines that served the
same purpose in existing code, and are no longer necessary.

This allows MOZ_TRY and MOZ_TRY_VAR to be transparently used in XPCOM methods
when compatible Result types are used.
Also removes a compatibility macro in SimpleChannel.cpp, and an identical
specialization in AddonManagerStartup, which are no longer necessary after
this change.

When used as an error value, nsresult should never be NS_OK, which means that
we should be able to safely pack simple nsresult Result values into a single
word.

We already periodically calculate the ghost window amount after cycle
collection, this just uses a cached value of that for the distinguished amount.
This avoids the overhead of a recalculating the value when reporting telemetry.

It appears some Android devices like to send spurious RT signals to our process
which we interpret to mean a gc/cc log is being requested. This causes large
files to pile up in the device storage. We can just disable this feature for
Android as it would be pretty hard for a user to actually use (they can just
go to about:memory). Automation can still enable the FIFO queue if we ever
want to start dumping memory reports on device again.

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.

This function takes up quite a bit of space, and there's no need to for
the log getter to be inlined everywhere. Moving this to out-of-line
code saves ~200K on x86-64 Linux.
The current definition of MOZ_LOG requires calling
LazyLogModule::operator() multiple times, which is unnecessary. We can
avoid that with a bit of clever macro definition and a lengthy
explanation.
As our threattype-listname conversion design, "goog-harmful-proto" is allocated
for this new threat type. This threat type is mainly for mobile.

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.

This callback is only used in very limited ways, so just require that
the caller pass in the canonical supports pointer, plus the
participant. This probably won't affect performance much.
