[MPlayer-dev-eng] non-free and undistributable files in tremor/

It's better to use r3989, because a word in the file 'COPYING' which the
headers refer to changed in that revision. The version after that date
has the same COPYING as is currently in MPlayer.

There's one extra change to sharedbook.c in r3989:

 static int sort32a(const void *a,const void *b){
-  return ( (**(ogg_uint32_t **)a>**(ogg_uint32_t **)b)<<1)-1;

This had the commit comment "correct sort32a in sharedbook.c". Hopefully
it's safe.
