I am applying this even though Reimar had some comments to improve it as it fixes
a serious security issue and I do not want to leave such things unfixed.

7dfed8e1dc 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
ffvorbis with libvorbis/tremor.

7d485f165f Support for getting (i)MDCT output multiplied by a constant scaling factor. 
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
'ff_mdct_init' function and slow down initialization a bit.

460c0abfbb 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

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
