Fix an issue uncovered by commit 20623:
...
The init functions of mpc7 and mpc8 check whether the vlc has been
initialized already and return early if this is the case (eg by calling
init a second time).
But avctx->sample_fmt and channel_layout is set after the vlc initialization,
causing it not to be set on the second call of init.
Move all manipulations of avctx before the initialization of the vlc,
so that it is always set.

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.
