Options

Move playback state, isLoading, and track selector result to PlaybackInfo. 

This is a no-op change replacing the local variables in ExoPlayerImplInternal
with the new ones in PlaybackInfo.

***
Use playbackState, isLoading and trackSelectorResult from playbackInfo in ExoPlayerImpl.

***
Move duplicated listener notification in ExoPlayerImpl to new method.

Also split reset method in one parts which creates the new playback info
and one part which notifies the listeners. The increment of the pending
operation counter needs to happen in between.

***
Use only one pending operation counter in ExoPlayerImpl.

This also allows to move onSeekProcessed into the notification chain.

***
Replace playback info changing messages to ExoPlayerImpl by single message type.

As they are all handled in the same way, they can be summarized to one message.

***
Only send playback info change notifications once per playback thread message.

This ensures that all concurrent changes actually reach ExoPlayerImpl concurrently.
