Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.
The URLPreloader's initialization code accesses the Omnijar cache off-main
thread. It can do so safely only as long as the main thread is blocked, or
running code which is guaranteed never to touch Omnijar, while its critical
section runs.
While that was guaranteed for previous versions of the code, some invariants
changed when we began using the component loader's shared global for initial
compilation. Once the global is created, we can safely use it to initialize
compilation. But creating the global invokes a large amount of Gecko code,
some of which touches Omnijar in the process.

This patch also ensures that we won't accidentally try stopping slow scripts
when we're shutting down the watchdog manager.

The last argument is always null, so we don't need this function any more.

The NS_LITERAL_CSTRING macro creates a temporary nsLiteralCString to encapsulate the string literal and its length, but AssignLiteral() can determine the string literal's length at compile-time without nsLiteralCString.

XPCOM's string API doesn't have the notion of a "null string". But it does have
the notion of a "void string" (or "voided string"), and that's what these
functions are returning. So the names should reflect that.

nsIHandleReportCallback, typedef of nsIMemoryReporterCallback, has been the
preferred name for a long time and is used in most places. This patch removes
nsIMemoryReporterCallback.

We don't have access to an appropriate context to create the dead wrapper in
when the callback is nuked, so instead, this patch creates a new dead wrapper
in the caller compartment each time the property is accessed. This is the same
behavior we'd get when trying to re-wrap a cross-compartment dead wrapper, so
it's consistent with the way we handle these situations elsewhere.

The script precompiler needs to begin its work very early in the startup
process in order to be effective. At the moment, this means before user
preferences are loaded. It also needs to be able to compile scripts into
the shared JSM global when that's in use, in order to avoid unnecessary script
clones.
Since we can't know whether global sharing is enabled by that point, instead,
we just always compile module scripts into the shared module global rather
than the XPC compillation scope.
This also changes the global sharing tests to make a failure to respect the
user preference value a fatal error.
