420df93037 mlpdec: Don't overallocate buffers.
Now that max channels and primitive matrices are properly validated, there is
no need to be paranoid that random data will be overwritten.
As a bonus this makes matrix_coeff 16-byte aligned between matrices.

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.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
