4ffe5e2aa5 huffyuv: add padding to classic (v1) huffman tables. 
We slightly overread the input buffer, so we require
padding at the end of the buffer, as is documented in the
get_bits API. Without padding, we'll read uninitialized
data or beyond the end of the .rodata, which may crash.

560f773c7d avcodec: change number of plane pointers from 4 to 8 at next major bump. 
Add AV_NUM_DATA_POINTERS to simplify the bump transition.

allocate separate pointer arrays.

fdb699de62 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.

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.

"Google Summer of Code participation" on the mailinglist.
