Back when mozalloc was a separate library, the xpcom glue code could not
use the infallible allocator API. But since bug 868814, that's not the
case anymore, so we can safely include mozalloc.h when XPCOM_GLUE is
set.

NoteIntentionalCrash is supposed to leave a marker that a process has crashed
intentionally, but if it can't open the target file it will crash the process
itself. This can cause difficulty debugging and false-positive results for
tests expecting crashes.

There's no good reason why these should't just be constants. The patch also
appends "MiB" to some of the C++ values to make their meaning clearer.
This patch fixes one outright bug, and one inconsistency.
The bug is due to a prefname mismatch:
- ContentPrefs.cpp and AvailableMemoryTracker.cpp use
"memory.low_virtual_mem_threshold_mb".
- all.js uses "memory.low_virtual_memory_threshold_mb".
Which means that "memory.low_virtual_memory_threshold_mb" showed up in
about:config, but if you changed it nothing would happen because the callback
listened for changes to to "memory.low_virtual_mem_threshold_mb"!
Now for the inconsistency. The above means we actually use a value of 256 for
the virtual memory threshold, even though all.js says 128. But we *do* use a
value of 128 for the commit space threshold, because that's what all.js says
and that prefname is used correctly everywhere. The patch changes the commit
space threshold to 256 for consistency with the virtual memory threshold.
What a mess!

There should be no functional change here, but we rely upon the new
structure in the next patch in the series. This separates out the
notions of removing a request from the load group (which is always
final, and must be executed outside of synchronous calls from the owner
of the imgRequestProxy) and wanting to readd a request to the load group
as a background request (for multipart images).
The most important addition is mForceDispatchLoadGroup which if true
when imgRequestProxy::RemoveFromLoadGroup is called, will dispatch the
removal from the load group instead of executing it inline. This ensures
safety for any callers (e.g. to CancelAndForgetObserver) as above.
This was created for B2G and isn't really useful otherwise. It only works on
Linux, and it's behind the memory.system_memory_reporter pref, which is false
by default.
The patch also removes LinuxUtils.{h,cpp}, which is no longer used.

And remove unreachable code after MOZ_CRASH_UNSAFE_OOL().
MOZ_CRASH_UNSAFE_OOL causes data collection because crash strings are annotated to crash-stats and are publicly visible. Firefox data stewards must do data review on usages of this macro. However, all the crash strings this patch collects with MOZ_CRASH_UNSAFE_OOL are already collected with NS_RUNTIMEABORT.

This change requires introducing nsID::Clone(). Because it's infallible, the
patch also removes some redundant failure-handling code. (nsMemory::Clone() is
also infallible, so this code was redundant even before this change.)

Bug 1134923 removed the use of those functions in gecko, and left some
for the XPCOM standalone glue. The XPCOM standalone glue was severely
stripped down in bug 1306327, with the effect of removing the
implementation for those functions.
The remains in nsXPCOM.h are:
XPCOM_API(void*) NS_Alloc(size_t aSize);
XPCOM_API(void*) NS_Realloc(void* aPtr, size_t aSize);
XPCOM_API(void) NS_Free(void* aPtr);
With no implementation left, the first arm is never actually used, and
the second arm means every remaining use of those functions in the tree
is a macro expansion to one of moz_xmalloc, moz_xrealloc or free.

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.
It seemingly hasn't been needed since Mac OS 10.7. A diagnostic assertion that
has been in place for a while hasn't caught any uses of it.
