Andreas Pehrson 1bdb34c6ec 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.

Differential Revision: https://phabricator.services.mozilla.com/D46146
