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
ffvorbis with libvorbis/tremor.

Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in

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.
