The old way is to start playing first, and then block the media element. This
way is too complicated because it involves lots of interal state and isn't intuitive.
The new way is to ignore the play if the media element should be blocked. It's
easy to know and we doesn't need to keep any internal states because we don't play
the media element.

We create audio channel agent in the beginning in oreder to use some agent's methods.
But the agent is still started after media element starting playing.

We uses "media-playback" event to notify fennec media control about media start
and end. However, if we resume media which was paused by media control, it won't
send any notification to JAVA side so that the MediaControlService can't change
the correct playing icon.
Therefore, we create new event to inform this situation.

Since I want to use more agent's functions in MediaElement and I don't think these functions need to be exposed on IDL level. (for other languages binding)
Therefore, I want to use AudioChannelAgent directly in MediaElement.

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.

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.

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.

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.

If the timer is currently running, add started time segment until now to
Total(), and add 1 to Count().
This ensures correct values are returned without having to Pause().

Note that this is a simple duration counter based on the existing (non-hidden)
play-time, but it only counts when video is playing while hidden.
There is no bucketing yet, future probes may add finer-grained information.

1. If mHasUserInteraction MediaElement is false, don't run the TimeMarchesOn because the element is not played. 2. Update the activeCueList only in TimeMarchesOn(). 3. Run TimeMarchesOn() at the beginning of play. r=rillian
