Various atom-related things have improved recently.
- The main atom table is now threadsafe (bug 1275755) and so can be accessed on
any thread. It has also been split into pieces (bug 1440824), which greatly
reduces lock contention.
- A cache has been added to the HTML5 parser (bug 1352874) that removes the
need for most of the full table lookups.
As a result, there is no point having a separate static atom table. This patch
removes it.

This macro is identical to NS_INTERFACE_MAP_END and encourages the
reader to think that there's something extra-special threadsafe about QI
implementations that use the macro, when in reality there's nothing of
the sort.
This patch adds a new environment variable XPCOM_MEM_LOG_JS_STACK that
changes XPCOM leakchecking to record a JS stack for all objects, in
addition to a C++ stack. This is useful when a C++ object is being
leaked due to JS. The JS stack will be printed if the object leaks, if
it is used in combination with XPCOM_MEM_BLOAT_LOG=1 and
XPCOM_MEM_LOG_CLASSES=nsFoo, if nsFoo is the class of interest.
This patch moves a few XPConnect functions for recording the stack
into xpcpublic.h so they can be called from nsTraceRefcnt.cpp.

This commit adds a paint worker thread pool to PaintThread, and dispatches
tiled paints to it. The thread pool is only created if tiling is enabled,
and its size is set by 'layers.omtp.paint-workers' and defaults to 1. If
-1 is specified, it will be sized to 'max((cpu_cores * 3) / 4, 1)'.
The one tricky part of dispatching tiled paints to a thread pool is the
AsyncEndLayerTransaction message that must execute once all paints are
finished. Previously, this runnable would be queued after all the paints
had been queued, ensuring it would be run after they had all completed.
With a thread pool, there is no guarantee. Instead this commit, uses
a flag on CompositorBridgeChild to signify whether all of the paints
have been queued ('mOutstandingAsyncEndLayerTransaction'), and after
every tiled paint it is examined to see if that paint was the last
paint, and if it is to run AsyncEndLayerTransaction. In addition,
if the async paints complete before we even mark the end of the
layer transaction, we queue it like normal.
The profiler markers are also complicated by using a thread pool.
I don't know of a great way to keep them working as they are per
thread, so for now I've removed them. I may have been the only
one using them anyway.

Most subclasses of Runnable don't bother to override AddRef and
Release, so XPCOM leak checking ends up reporting Runnable, which
makes it impossible to know what is actually leaking.
Each subclass of Runnable is already required to pass in the name of
the class, which is stored in the field mName. This patch changes
Runnable to use mName as the class name for XPCOM leak checking, thus
giving each subclass a specific name without needing to change the
hundreds of existing subclasses of Runnable.
The limitation of this approach is the classes that DO use
NS_IMPL_ADDREF/RELEASE_INHERITED end up using the same class name that
is used by the superclass AddRef/Release, but with a different size,
which causes assertions in the leak checker. To work around this, I
change NS_IMPL_ADDREF/RELEASE_INHERITED to not call into
NS_LOG_ADDREF/RELEASE for classes that are a subclass of
Runnable. This needs to use IsConvertible<> and not IsBaseOf<> because
the latter requires the classes involved to be defined, and headers
can use nsISupportsImpl.h without nsThreadUtils.h.

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

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

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.

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.
