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.

Merge the 2 lpc loops.

This changes the output by (stddev: 0.21 PSNR:109.51, file:ddinterview28.ra),
the changes are due to float rounding inaccuracies and do not happen if doubles
are used.
