Try to set AVFrame.reference to correct values.
I am not sure these new values are correct, not am I sure
the semantics are a good idea since we do not seem to make any
use of them but they caused a lot of confusion, but this
seems to make things closer to matching the documentation.

Fixed deference of NULL pointer in motionpixels decoder.
Some of the arguments given to init_vlc() come from the stream

lavc: set defaults in internal codec frames
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.

None of these symbols should be accessed directly, so declare them as

10l, pix_fmt should be set by the motionpixels decoder, not by the demuxer.

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.
