using the appropriate predictors.

Fix passing of unaligned addresses to dsputil diff_bytes() by

changeing calls to sub_left_prediction such that
the source frame data pointers are no longer offset to skip the initial
elements. This keeps them properly aligned for the subsequent call to diff_bytes.
Changes encoding offset to compensate.

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.
