The FunctionBroker actors allow the NPAPI process (child) to run methods on the main process (parent). Both the parent and the child run dedicated threads for this task -- this is a top-level protocol.

Historically, PSM has handled tracking NSS resources, releasing them, and
shutting down NSS in a coordinated manner (i.e. preventing races,
use-after-frees, etc.). This approach has proved intractable. This patch
introduces a new approach: have XPCOM shut down NSS after all threads have been
joined and the component manager has been shut down (and so there shouldn't be
any XPCOM objects holding NSS resources).
Note that this patch only attempts to determine if this approach will work. If
it does, we will have to go through alter and remove the remnants of the old
approach (i.e. nsNSSShutDownPreventionLock and related machinery). This will be
done in bug 1421084.

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.

The nsGIOService now provides GetAppsForURIScheme which is used to append handlers
for specific scheme in handler list dialog (toolkit/mozapps/handling/content/dialog.js)
and also in Applications section in preferences. In case the default system handler
or user added handler has same name as one of the GIO handlers, the GIO handler
is not appended. The check for not adding handler is by using handler name.
The nsGIOMimeApp class now implements nsIHandlerApp interface. Instead overloaded
GetName methods (nsCString and nsString) we now use nsString variant everywhere.
This require change of nsGNOMERegistry::GetFromType which if fact leads to code
simplification.
The implementation of nsGNOMEShellService::SetDefaultBrowser has been changed
because implementation of CreateAppFromCommand has changed.
The CreateAppFromCommand no longer tries to find the application,
for that FindAppFromCommand has been introduced.

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.

The std::nothrow variant of operator new is effectively a fallible
operator new. It is used in third party code.
The duplication with our own fallible operator new is unfortunate, and
we can reduce it by making one an alias of the other.
We keep the fallible library as a dummy on Android because bug 1423802
induces some linking problems.

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

2. If a substream is async, available() should not check following streams
until that is closed.
