6752dd5aee Loop up to MAX_THREADS instead of h->s.avctx->thread_count to free the thread
contexts, this avoids a crash when freeing the H.264 parser context introduced in
r18406, since h->s.avctx is NULL there.

15861962a7 Add a ff_h264_free_context function and call it from the H.264 parser.
This ensures that the parser will no longer leak memory for all SPS/PPS it encounters.

c81185a183 Make sure mpeg2 has its height rounded up to 32 as that is needed

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.
