MediaPlayer cleanup, part one of N
Get rid of a lot of dead code in MediaPlayer and associated classes,
and simplify MediaPlayer now that there's only a single MediaEngine
to worry about.
Note that this is just the beginning: there's clearly lots more to be
done, and some the layers here probably no longer need to exist.
