Remove BasePlayer stop as a final method.

It calls through to a deprecated method, which is unusual for a
convenience method, and the deprecated method has various
implementations. This allows for a smoother removal of stop(boolean)
and removes an obstacle for the ExoPlayer-SimpleExoPlayer merge.

Adds missing @Deprecated tags to some Players.
