399a9cb58a Bug 1611031 - always trigger corespending controller method when receving media control key events. r=chunmin
The check here was used to prevent calling play or pause during playing or pausing.

However, according to the spec [1], even if media session is playing, we would still want to trigger its play action handler when play action happens. So we should forward all media control key events to the content, not to block any of them.

d3d8a3d56e Bug 1595603 - part2 : delay seeking task when media is inactive r=bryce
When media element is inactive, asking MDSM to seek is actually useless, because all the data we decode won't be showed to user. In addition, we have to store extra pending events for `seeking` and `seeked`, which might result in memory overflow if the inactive page is calling `seek()` all the time.

Therfore, we should delay all seeking tasks while media is inactive, and perform the latest seeking task when media becomes active.

0e0b0572c4 Bug 1595603 - part1 : remove duplicate parameter and rename variable r=bryce
Two parameters in `SuspendOrResumeElement()` are acutally the same, they are both related with `IsActive()`, so using one parameter is enough.
In addition, we only suspend or resume element by checking element's active state, so rename `mPausedForInactiveDocumentOrChannel` to `mSuspendedForInactiveDocument` which fits the actual situation more.

aa180f8e57 Bug 1571493 - part2 : use 'MediaControlAgent' in media element. r=chunmin
We create `MediaControlEventListener` to register itself to the `MediaControlAgent` that is an event source, so that we can receive the media control event from the evnet source and operate media according to different types of event.

 `MediaControlEventListener` is also used to notify controlled media state to the media controller. When media first starts playing, or leaves bfcache and  has created listener before, we would notify `eStarted`. Notify `eStopped` when media destroys, or enter bfcache and has created listener before. When media's playing state changes, we would notifty `ePlayed` or `ePaused` depeding on media's `mPaused`.

df0ca96677 Bug 1588138 - reset blessed state when media aborting current load. r=bryce
This patch is used to change the blessed state for media element under `click-to-play` blocking autoplay policy, which only allows play invocation called from user input handler, eg. `onclick`.

When media aborts current load, we should regard it as a new media. One example is on Youtube they always reuse same media element but replace its url for different video. Therefore, we should reset media's blessed state so that the media with new url can be blocked again.

ab7aa64018 Bug 1172394 - Merge MediaStream and MediaDecoder track sources. r=padenot
This reworks how media element captureStream works by removing the differences
between MediaStream and MediaDecoder capture. MediaDecoder capture will be
refactored so that ownership of MediaStreamTracks lies with the media element
instead of the OutputStreamManager. The internal MediaDecoder parts happen in a
later patch.

The new API for capturing a MediaDecoder involves a boolean on/off toggle, the
output tracks the decoder pipes data to, and the principal that data is tagged
with. If capturing is on but there are no output tracks, playback will not
happen, to ensure that no data gets accidentally skipped in the output tracks
while captured.

This also changes the logic for setting up MediaElementTrackSources in
HTMLMediaElement so it's triggered by the WatchManager and thus run in tail
dispatched runnables.

This change mainly removes the `mTracks` member from MediaStream and moves all
associated members up a level, so that a MediaStream in practice represents a
single track.

Classes will be renamed in a future patch to reflect this.

Other changes include:

The new `mEnded` member of MediaStream changes meaning to only become true when
all data in the stream has been processed. It stems from
StreamTracks::Track::mEnded which used to become true as soon as the last bit of
data had been added to a track, and there could still be data in the track that
would get processed in future iterations. We are moving towards not having any
future data in tracks, which is why this change is ok to make -- keeping the old
behavior will soon not make sense.

TrackUnionStream is changed to no longer take a list of streams as input and
forward the union of their tracks to itself. Instead it's limited to having one
track as input at a time.

The autofinishing functionality that TrackUnionStream had before has been
transformed into an autoending functionality to allow it to defer ending until
its been told that it's ok to end through the control API. This lets a single
TrackUnionStream span the lifetime of multiple inputs, which will be useful for
making DecodedStream spec compliant with HTMLMediaElement::CaptureStream(), and
for implementing the currently discussed MediaRecorder::ReplaceTrack(), to name
a few potential use cases.

AudioNodeStreams used to only have a track (and thus an AudioSegment) if the
EXTERNAL_OUTPUT flag was enabled on them. With all MediaStreams now representing
a track, AudioNodeStreams inherently have an AudioSegment as a member. It is
however only used with data if the EXTERNAL_OUTPUT flag is enabled.

f8f05851a5 Bug 1454998 - Remove track blocking from MediaInputPort. r=karlt
This functionality is not used since we moved to only having a single track per
MediaStream (bug 1493613).

6a28f98fed Bug 1454998 - Rename streams to tracks. r=padenot,karlt,smaug
This renames the following (in alphabetical order, non-exhaustive):

AudioCaptureStream -> AudioCaptureTrack
AudioNodeStream -> AudioNodeTrack
AudioNodeExternalInputStream -> AudioNodeExternalInputTrack
DirectMediaStreamTrackListener -> DirectMediaTrackListener
MediaStream -> MediaTrack
  - Note that there's also dom::MediaTrack. Namespaces differentiate them.
MediaStreamGraph -> MediaTrackGraph
MediaStreamTrackListener -> MediaTrackListener
MSG -> MTG (in comments)
ProcessedMediaStream -> ProcessedMediaTrack
SharedDummyStream -> SharedDummyTrack
SourceMediaStream -> SourceMediaTrack
StreamTime -> TrackTime
TrackUnionStream -> ForwardedInputTrack
  - Because this no longer takes a union of anything, but only a single track
    as input.

Other minor classes, members and comments have been updated to reflect these
name changes.
