10l (updating LRU delta pts for type 1/2 frames)
ensure that checksumming isnt enabled if its not needed
search for next startcode and then search backward to the next valid frame if an inconsistancy is detected
deal with non-frame startcodes in the middle of the stream

some random id for vorbis so we can do some experiments with vorbis in various containers, anyone knows if vorbis in WAV/AVI has a official id?

Originally committed as revision 2961 to svn://svn.ffmpeg.org/ffmpeg/trunk

use 3 pts predictors for vorbis, slightly more efficient

 conform to latest spec
 remove get/put_s() not needed anymore
 update_packetheader() fixed (wasnt always working)
