Add setters to MediaSource factories for custom window tag.

Browse source 
This field (formerly "id") is almost impossible to use so far. Having setters
in the factories allows to specify custom tags for all media sources.

Also added a ExoPlayer.getCurrentTag() method to retrieve the tag of the
currently playing media source in a convenient way.

* Added callbacks to `MediaSourceEventListener` to get notified when media
periods are created, released and being read from.
* Support live stream clipping with `ClippingMediaSource`.
* Allow setting custom tags for all media sources in their factories. The tag
of the current window can be retrieved with `ExoPlayer.getCurrentTag`.
* Audio:
* Factor out `AudioTrack` position tracking from `DefaultAudioSink`.
* Fix an issue where the playback position would pause just after playback
