- Remove manifest argument from callbacks of Player.EventListener and
SourceInfoRefreshListener. Instead make it accessible through
Player.getCurrentManifest() and Timeline.Window.manifest.
- Fix all MediaSource implementation to include the manifest in the
Timeline instead of passing it to the SourceInfoRefreshListener.
- Refactor ExoPlayerTestRunner, FakeTimeline, FakeMediaSource to
reflect these changes and make tests pass.
