added dc.next_song, renamed pc.current_song

Since pc->current_song denotes the song which the decoder should use
next, we should move it to DecoderControl.  This removes one internal
PlayerControl struct access from the decoder code.

Also add pc.next_song, which is manipulated by the playlist code, and
gets copied to dc.next_song as soon as the decoder is started.
