Sync the bitstream functions with ffmpeg.  Switch wmadeci.c over to get_vlc2 which is how ffmpeg now does it and is also slightly faster.  Add in defines for later VLC memory usage optization.  Kill some header files that weren't needed and update others that were out of sync.  We're now much closer to the current ffmpeg codec which should make fixing the remaining issues much easier.
