Motown: Change player state machine to support preroll
This CL changes the internal logic of MediaPlayerImpl so that an initial
call to the Pause method will cause the first frame of video to be
displayed. Logic around priming/flushing the pipeline was previously
handled using a separated state variable (flushed_). This CL removes
that state variable and replaces the internal kPaused state with
kFlushed and kPrimed. The pause method is treated as a request to
enter kPrimed state, in which packets will be queued for rendering (so
the first video frame can be shown). The player starts in kFlushed state
and only transitions back to that state in order to seek.
