295a7c0238 4xm: Prevent buffer overreads.
4xm decoder while decoding i2 frames can overread the buffer if proper checks
are not made.

4b84f68223 4xm: pass the correct remaining buffer size to decode_i2_frame().
frame_size is the number of bytes left in the packet, so if we are passing
buf-4 we can safely read frame_size+4 bytes.

893f137679 4xm: fix calculation of the next output line position in decode_i2_frame().
The current code doesn't work unless width is an exact multiple of 16.

bc78ceec2b 4xm: remove unneeded check for remaining unused data.
This is unnecessary complication that only prints a message and does not
affect decoding.

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.

"Google Summer of Code participation" on the mailinglist.
