sync-to-sync data loss
I believe there to be a bug in sync.c's buffer handling whereas it doesn't
appear to be incrementing the buffer size when pages that come from one
ogg_sync_state object are passed into another. In the tests I've run, using
Vorbis files to test with, I've been getting between 30% to 40% of the page
data I put in.
The data comes out unmangled but "short" in length. ogginfo shows the output
to be a normal Vorbis file, only shorted than it should be and lacking EOS.
I have only seen this error by using py-ogg2 and have not attempted to
replicate this with a C program, however I looked trough py-ogg2's sync.c and
saw nothing that could cause a bug such as this. It's really just glue code
between Python and libogg2, and it seems to work fine for full encoding and
decoding.
