Motown: Define MediaRenderer and make it the way we identify renderers.
Previous to this CL, we had no standard way to expose/identify renderers
independent of media type. AudioTrack exposed the audio renderer in an
audio-specific way, and there was no video renderer. This CL defines
MediaRenderer, which largely replaces AudioTrack. It supports media type
negotiation and provides access to the MediaTimelineControlSite and the
MediaConsumer associated with a renderer. URLs have been removed from
the media interface definitions altogether.
