ae3d819970 pt3: init zeroed vars with loop 
switching songs, sometimes they'd start wrong due to vars not
being initialized.  Easier to just zero everything than try to
figure out which field we weren't getting.  Also makes code smaller.

73d9b710c7 pt3_lib: add directory with just the pt3 player 
This will be less optimized than pt3_player but possibly
easier for other programs to use.
