This will also allow multiple audio/video SourceBuffers for a single MediaSource. Note that for now we'll still only select/play the first audio and video track by default. Switching between tracks will require further work in media renderers. A few notes: Most of the changes are straightforward, except media_source_state.* In order to allow multiple tracks in a single SourceBuffer, we'll now pass the codecs parameter from WSBI further down to ChunkDemuxer and MediaSourceState, replacing the old has_audio/has_video flags. The new MSS::OnNewConfigs structure is much closer to the MSE init segment handling algorithm, with essentially the same logic for handling new/existing track ids and such.
