4f717c69ed idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. 
Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

b750fb6945 Display dimensions should not affect the real size of coded frame, thus set 
only avctx->{width,height} and don't touch coded_{width,height} when parsing
them. This fixes the case when coded and display dimensions differ by more
than one macroblock.

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.
