- Handle titles that use more than one PGC (like the one in this thread: http://forum.handbrake.fr/viewtopic.php?f=5&t=10678&p=55575&hilit=genesis#p55620).

 - Make pgcn_map local rather than static since there can be simultaneous scans from both GUI and queue service threads and statics aren't thread safe. Also make map 32 bytes since standard allows only 255 PGCs per title.
 - Fix minor bugs in NextPgcn (used pgcn rather than next_pgcn so tested wrong bit) and dvdnav_seek (missing 'break' & extraneous 'while').
