Optimize ff_snow_horizontal_compose97i.
...
this makes the 9/7 C wavelet at the decoder side 22% faster.
The old code is changed to match the new in terms of the order of operations
(which also makes it sligtly faster)

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.
