cc51b28299 Split cabac decoding code out of h264.c. 
not slower according to benchmarks.

e1e949026e Split cavlc out of h264.c. 
Seems to speed the code up a little...
The placement of many generic functions between h264.c and h264.h is still open
Currently they are a little randomly placed between them.

2bedc0e854 Move check_intra4x4_pred_mode() back from h264.h to h264.c, the function is just 
called once per MB in worst case and doesnt seem to benefit from static inline.
Actually the code might be a hair faster now (0.1% according to my benchmark but
this could be random noise)

903d58f631 Get rid of #include "svq3.c" 
functions called more than per mb are moved into the header, scan8 is also
as it must be known at compiletime.
The code after this patch duplicates h264data.h, this has been done to minimize
the changes in this step and allow more fine grained benchmarking.
Speedwise this is 1% faster on my pentium dual core with diegos cursed cathedral
sample.

0410ee8f86 H.264: Don't set data_partitioning for invalid NAL_DPA.

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.
