Perform the DC prediction reversal immediately after decoding all of
...
the DC coefficients. This has a greater probability of leveraging the
coefficients while they are still cached.
When testing with the Big Buck Bunny 1080p video, I consistently saw
improvements of 500k-600k dezicycles per run (through
reverse_dc_prediction()) thanks to this move.

Otherwise this will crash during decoding because the vlc tables are NULL.

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.
