When we shutdown the browser while the GMPService is active we can end up
leaking a GMPParent, GeckoMediaPluginServiceParent, and a Runnable. I tracked
this down to the runnable dispatched to the GMP thread in
GMPParent::ChildTerminated(). The dispatch of this runnable is failing as we
are dispatching the runnable to a reference of the GMP thread which we have
previously acquired, but that thread is now shutdown. So the dispatch fails,
and if you look in nsThread::DispatchInternal() you'll see that we deliberately
leak the runnable if dispatch fails! The runnable leaking means that the
references it holds to the GMPParent and the GMP service parent leak.
The solution in this patch is to not cache a reference to the GMP thread on the
GMPParent; instead we re-request the GMP thread from the GMPService when we
want it. This means that in the case where the browser is shutting down,
GMPParent::GMPThread() will return null, and we'll not leak the runnable. We'll
then follow the (hacky) shutdown path added in bug 1163239.
We also need to change GMPParent::GMPThread() and GMPContentParent::GMPThread()
to return a reference to the GMP thread with a refcount held on it, in order
to ensure we don't race with the GMP service shutting down the GMP thread
while we're trying to dispatch to in on shutdown.

X11.h #defines 'Status' and 'Failed' and 'Succeeded' which conflicts with
the enum in DetailedPromise. So rename the 'Status' enum in DetailedPromise
so that the build works on Linux.
Some of my changes here caused DetailedPromise to be included in more
places that it was before, which caused build failures on Linux.

At this stage, I store video frames in memory in nsTArrays rather than in
shmems just so we can get this working. Once this is working, I'll follow up
with patches to switch to storing all large buffer traffic between the CDM and
other processes in shmems.
I'm not planning on preffing this new CDM path on until that's in place.

The MediaKeys accesses the ChromiumCDMProxy on the main thread. But the
ChromiumCDMVideoDecoder will need to access the ChromiumCDMProxy on the decode
task queue in order to get a reference to the ChromiumCDMParent so that it can
talk to the CDM (on the GMP thread).
Additionally we'll need to shutdown the ChromiumCDMProxy, and if we do that
on the main threrad while the ChromiumCDMVideoDecoder is trying to get the
ChromiumCDMParent reference, we could hit thread safety issues.
So we need to hold a lock while reading or writing from the ChromiumCDMProxy's
reference to the ChromiumCDMParent. So add a GetCDMParent() function to the
ChromiumCDMProxy which takes the lock while reading or writing the reference.
This means that the caller will always get a valid reference. There is no guarantee
that the ChromiumCDMParent isn't shutdown after the reference is taken; if that
happens, the ChromiumCDMParent returned will fail on all operations.
In a later patch in this series, the ChromiumCDMProxy will anull its reference
to the ChromiumCDMParent on shutdown, and cause GetCDMParent to return null.
So callers need to null check the return value of GetCDMParent.

We currently use an adapter object to adapt plugins that don't conform to the
GMP interface to the GMP interface.
We use the WidevineAdapter to talk to the CDM from the two GMP IPDL protocols.
We will be using a single protocol to talk to the Chromium CDM, so we need a
new adapter which handles that.

We currently do two sync IPCs to launch a GMP; one from content to main process
to get the nodeId and a second to get a GMPContentParent for that nodeId.
We use the nodeIds to ensure that the GMPVideoDecoder and GMPDecryptor actors
correspond to the same CDM instance/process. However once we switch to having
one protocol that encompasses both decryption and decoding, we don't need to
worry about making sure our decoder and decryptor actors match up, as we only
have one underlying connection to the CDM instance.
So we can merge the get nodeId and get GMPContentParent operations into a
single operation that does both. To do this, we just need to pass the
parameters used to calculate the nodeId in the LaunchGMP message.
Once we've switched EME over to using the CDM via a single actor, we can remove
the nodeId nsCString from our media code and from GMPVideoDecoder and
GMPVideoEncoder.

This patch adds logging to some important functions that currently lack it.
Thread registration/unregistration is done with DEBUG_LOG because it's
more verbose than the other profiler logging, but less verbose than LUL's
logging.
The patch also scraps the BEGIN/END logging pairs because they bloat the output
for little gain. Now it just logs on function entry.

It's a very general mechanism for replacing the implementation of
printf_stderr().
It's primarily used by the profiler, sparingly, and not in an important way.
Worse, it prevents us from using MOZ_LOG in the profiler, which is something I
want. Because if any code that locks gPSMutex also calls MOZ_LOG, that then
calls printf_stderr(), which calls profiler_log(), which locks gPSMutex, which
deadlocks.
The only other use of set_stderr_callback() is for the ultra-hacky,
for-local-use-only copy_stderr_to_file() function, which was added for B2G
debugging and is no longer necessary.
This patch removes set_stderr_callback() altogether.

The following functions all call NS_LogInit() (either directly or via
ScopedLogging) and then call LogModule::Init() very shortly after:
XRE_InitChildProcess(), NS_InitXPCOM2(), NS_InitMinimalXPCOM(),
XRE_XPCShellMain().
XREMain::XRE_main() does not, however. This prevents us from using MOZ_LOG
easily in the profiler, because the profiler starts up earlier than logging in
the browser.
This patch adds an early LogModule::Init() to XRE_main(), just after the
NS_LogInit().
