681c180dc4 Make avcodec_open set codec_id and codec_type if they haven't been set. 
This fixes the API breakage introduced by the check that avctx codec id and type
match the opened codec and should make (almost?) all applications work again.

4c0dda2b3f Check codec_id and codec_type in avcodec_open(), based on 43_codec_type_mismatch.patch from chrome 
This is said to be able to lead to a stack based buffer overflow.

10f9ff9bf6 Set AV_PKT_FLAG_KEY in avcodec_decode_video. 
This fixes decoding of MPNG, which currently is incorrectly decoded as
CorePNG delta frames.
CorePNG can not be correctly decoded via this old API either way.

f988ce6cad Add a lock manager API to libavcodec. 
Allows an application to register a callback that manages mutexes
on behalf of FFmpeg.
With this callback registered FFmpeg is fully thread safe.

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.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.
