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.

ac3dec: Remove unneeded context variable, num_cpl_subbands. It is also

not needed for spectral extension or enhanced coupling since it is
redundant information, so I am removing it from decode_band_structure()
as well.

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.
