This can reduce the include header dependency. MediaStreamVideoSink will inherit from DirectMediaStreamTrackListener. But we can't use forward declaration on MediaStreamListener because the usage of nsTArray<RefPtr<MediaStreamVideoSink>>.

This enables callers to specify a way to determine the correct window to
dispatch the PluginCrashed event to should the GMP actor crash.
We need a way to determine the correct window at crash time, as the GMP's
window can change at runtime. For example, if the GMP is being used for
unencrypted decoding, the <video> element can be moved to a new browser window
at runtime.
Note: I don't handle disconnecting the GMPCrashHandlers in this patch; we do
delete the GMPCrashHandlers in this patch when their associated GMP crashes, and
in the next patch we handle disconnecting GMPCrashHandlers in the case where
we don't crash.

Call the device binding code in gtests, and have a test GMP which returns the
device ID it was passed in a message, so that we can verify that the id the GMP
was passed is the same as the id generated in the parent.

I want the EME device binding/nodeId code to be callable from gtests, as well
as in plugin-container. I need this because I want to add a gtest that ensures
that we don't regress the EME/GMP device binding code. I want to call the GMP
device binding code in the gtest and in the GMP process, and compare the
result.
So we need to make it possible to link the device binding code into the gtests
as well as plugin-container. So move all code that device binding calls into
librlz, to make it easier to link against all the code required.
Note: the device binding code needs to be statically linked into
plugin-container so that it's covered by the Adobe CDM's voucher tool.

Now that GMPParent detects whether gmp-clearkey can decode using AAC/H.264
using WMF before reporting gmp-clearkey's GMPParent can decode AAC/H.264, we
don't need the GMPDecryptorCallback::SetCapabilities() callback from the GMP to
signal to the PDMFactory that the GMP can decode. We can now trust what the
GMPService tells us.
So we can remove the "waiting for CDM caps" step in the state machine's startup
sequence. And all the plumbing. :)
If we need more caps, like for an decode-and-render path, we can declare those
as API strings in the info file.

GeckoMediaPluginService::mAbstractThread was not reset as expected from
ShutdownGMPThread, meaning it would retain a reference to the GMP thread, and
it would allow dispatch attempts to the GMP thread after shutdown.
Also mAbstractThread was not protected by a mutex (as mGMPThread was), which is
definitely needed now that it can be reset at shutdown time.
As its prefix implies, GetAbstractThread could return a nullptr, so it should
be checked before every use.
Note that this GetAbstractThread call (and its check) has been moved closer to
the start of functions using it, to avoid unnecessary and potentially invariant-
breaking partial work to take place when we can know in advance that it won't
fully succeed because the GMP thread is not available.

Pass declared-but-yet-undefined DecoderDoctorDiagnostics pointer to various
routines that contribute to deciding if a media format can be played, and
those that create decoders.
Points where a DecoderDoctorDiagnostics can be injected are currently marked
with "/* DecoderDoctorDiagnostics* */ nullptr", and some will be used in
following patches.

Now that adding GMPs to the GMP service is async under the hood, for safety
the GeckoMediaPluginServiceParent needs to expose when adding a GMP
has finished so that things that depend on GMPs being present can be reliable.
For example, the call to GMPDecoderModule::UpdateUsableCodecs() that happens
at the end of AddPluginDirectory depends on the GMPs being up to date, so it
needs to happen after the add has finished.

PrincipalHandle is a thread safe pointer to a holder of (the main-thread-only
nsIPrincipal) that can be passed around the MSG.
A MediaStreamTrack whose source has just updated its principal, sets the new
principal aside (as its "pending principal"), and combines the new principal
into its current principal.
Then the source starts passing the new principal to the MediaStreamGraph as
a PrincipalHandle.
Changes to a track's PrincipalHandle on the MSG will be surfaced through the
MediaStreamTrackListener API. These changes are dispatched to main thread
and compared to a MediaStreamTrack's pending principal. In case of a match
the track knows the correct principal is flowing and can move the pending
principal to be the current principal and update any main thread principal
observers.
