olly 99957bbae7 Correctly handle dynamic playlist modifications
- Fix bug where we'd try and call replaceStream having already
  notified the renderer that the current stream is final. This
  could occur if a period was added to the end of the playlist.
- If the current period being played is removed and a new period
  to play cannot be resolved, assume we've gone off the end of
  the playlist and transition to the ended state. This allows
  the current source to be re-used (unlike the previous behavior
  of considering it an error). Treat valid seeks that cannot be
  resolved due to concurrent timeline update similarly.
- Add seek sanity check back to ExoPlayerImpl. Meh. It's probably
  best to keep this, since it stops the exposed window index
  being invalid w.r.t the exposed timeline.
