Enable nsAttrValue::EnumTable to be initialized with enum. So, we could get rid
of the castings in EnumTable. Fix EnumTable initialization comment.
For those untyped enumerations, declare them with uint8_t, as to other typed
enumerations with type size larger than int16_t, force casting to int16_t.
Use {nullptr,0} instead of {0} to represent the last entry.

In ancient degisn, we would only register audio channel after the media element has audio track and enoguh data to playback,
that is because the "audio-playback" event would be dispatched with the registration, and then shows the tab audio indicator.
However, now the event dispatching doesn't follow with the registration, it would be triggered when the media element has
really audible data which would be notified from media decoder.
Therefore, the media element without audio track or without enough data can also register audio channel agent, it won't affect
the display of tab audio indicator. The reason we need to do that is for blocking autoplay media in the non-visited tab.
The autoplay can be adding "autoplay" keyword or playing by the script, and we don't want to dispatch dom event for blocked
media. Therefore, we should register audio channel agent to know whether it needs to be blocked immediately even the media
element doesn't have any enough data which can let us to distinguish it have any audio track or not (this information can
be known from metadata).
First, we must check whether the media is blocked which is notified by audio channel agent, and then we can decide whether
need to dispatch the event. If we don't register audio channel agent, that we can't get blocking information.

If the media was blocked, we would postpone the dom event and dispatch them after media is resumed.

This adds support for HTMLMediaElement.mozCaptureStream() and
mozCaptureStreamUntilEnded() for a HTMLMediaElement playing a MediaStream.
This is up to spec, while capturing a HTMLMediaElement playing a file is not.
This incompatibility means we cannot mix sources for the returned MediaStream.
As such, a MediaStream returned while the HTMLMediaElement was playing a file
will only have content while the element is playing files. If the src changes
to a MediaStream, the stream will be empty.
It works the same way if a MediaStream was captured while the HTMLMediaElement
was playing another MediaStream.
This is due to TrackID management - MediaDecoder doesn't care, and creates new
tracks when you seek, so users are unable to keep track, while for MediaStream
we control everything from main thread and keep track of the TrackIDs used
previously.
This also adds a separate path from MediaElementAudioSourceNode so that we don't
forward video tracks when the returned MediaStream is only used internally for
WebAudio. We should in that case not require a DOMMediaStream but just forwarding
tracks to a TrackUnionStream should be enough, and will save us some cpu cycles.
This is however fine for now as it's simpler.

Sometimes a track is added to a stream synchronously (before the stream is
exposed to script), and sometimes asynchronously (see the mediacapture-main spec
on the "addtrack" event).
In the latter case we might still need to create the MediaStreamTrack object
synchronously for tracking purposes. CaptureStream of Media element playing a
MediaStream wants this.

On Linux x64 PGO try, HTMLMediaElement was reliably invoking
decoder->NotifyOwnerActivityChanged() after SetVisible(false) was
called. This caused the pending suspend to be cancelled and the test
waits for an event that never arrives.
Fixed by adding 'forced hidden' to MediaDecoder that overrides the
element visibility that comes from HTMLMediaElement.

Bubble information from SamplesWaitingForKey to an HTMLMediaElement so that we
can emit a waitingForKey event. If we are unable to decode more samples due to
needing a key the event will be signalled. See
http://w3c.github.io/encrypted-media/#dom-evt-waitingforkey for more information
on this event.
The code in place before this patch handles updating readyState when we are
waiting for a key, this patch adds the event which should be emitted in such a
case. The spec defines certain preconditions should be the case before running
the algo to emit this event. For example, the element should potentially be
playing, and it should have at least HAVE_FUTURE_DATA ready state. This is not
strictly true for when the new code is run, due how existing code handles ready
state. We are honoring the spirit of the spec, though the letter of the spec is
lightly gone against in the handling of the preconditions.

found when playing a video (played for at least enough time to be eligible for

This patch makes most Run() declarations in subclasses of nsIRunnable have the
same form: |NS_IMETHOD Run() override|.
As a result of these changes, I had to add |override| to a couple of other
functions to satisfy clang's -Winconsistent-missing-override warning.

After a video has been playing while hidden for a certain time, count the time
until it is not hidden anymore (or it has finished playing), to test-drive how
much decoding time would have been saved by the video-decode-suspend feature.
Note that this is done inside HTMLMediaElement by simulating what should happen
in the MDSM, because instrumenting the MDSM itself and friends would have been
harder and more intrusive.

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.
