58b2e0f0f2 vqavideo: return error if image size is not a multiple of block size
The decoder assumes in various places that the image size
is a multiple of the block size, and there is no obvious
way to support odd sizes.  Bailing out early if the header
specifies a bad size avoids various errors later on.

Fixes CVE-2012-0947.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

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.
