Currently our Renderer is always associated with and consume data from some SampleStreams, which were constructed from the provided MediaSource. There are use-cases, in which the users want to have simple Renderer implementation that does not consume data from SampleStream at all, but render using their custom logic at each rendering position - they mostly just need ExoPlayer to keep track of the playback position and enable/disable the renderer. This CL adds support for such Renderer by adding a TRACK_TYPE_NONE. Renderer of such type will be: - Associated with null TrackSelection as the result of track-selection operation. - Associated with EmptySampleStream.
