Better handle duration + disabled renderers

Browse Source 
- Fix bug where duration of initially disabled tracks wasn't correctly
  incorporated into the overall duration reported by the player.
- Don't transition to STATE_ENDED unless the position has reached the
  duration, if the duration is known. This allows for "playback" to
  continue when all renderers are disabled, rather than jumping straight
  to STATE_ENDED.
