Because the TaskQueue of MDSM will shut down soon and TaskQueue::Dispatch() will fail (via mOnOutput.Notify()).
We reset mStream in Forget() on the TaskQueue thread of MDSM so NotifyOutput() can check it
and ensure mOnOutput.Notify() always happen before DecodedStream::Stop().

In this patch, we first deal with the case of MediaElement. Now we replace |PlayVideo| with |VideoFrameContainer::SetCurrentFrames| in |SourceMediaStream::AppendToTrack|. The MSG use TimeStamp::Now() for the TimeStamp of each video frame in most of case except MediaElement case. Becasue the MediaElement has its own VideoQueue, we need to calucalte the correct Timestamp based on the StartTimeStamp of this MediaStream and the elpased time of the video frame in DecodedStream.

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>>.

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.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

We don't want to block stream decoding on the output MediaStream, or vice
versa.
