Fix for a problem with inverted sign of output data from ffvorbis decoder.

Now the sign of audio samples in ffvorbis output is the same as in original
uncompressed audio file and this also allows the use of tiny_psnr to compare

Fix for issue #829 ("ffvorbis outputs crackling sound, libvorbis plays fine")

This was off-by-one bug which affects floor0 encoded files. Tracked down
by valgrind (was reported as the use of uninitialized memory).
With this patch applied, tiny_psnr now reports the following when ffvorbis
is compared to libvorbis-1.0beta4 output for 'lsp-test.ogg' sample:
stddev: 0.76 PSNR: 98.69 bytes: 3498380/ 3498452
Output from libvorbis-1.2 is substantially different:
stddev: 132.57 PSNR: 53.87 bytes: 3498424/ 3498496

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows

flag, which appears necessary to playback corePNG P-frames.
