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.

This is required specifically for setting frame->format to -1,

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.
