c90b94424c 4:4:4 H.264 decoding support
Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.

6e3ef511d7 Add the notion of pixel size in h264 related functions.
In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.

2a1f431d38 H.264/SVQ3: make chroma DC work the same way as luma DC
No speed improvement, but necessary for some future stuff.
Also opens up the possibility of asm chroma dc idct/dequant.

5657d14094 H.264: switch to x264-style tracking of luma/chroma DC NNZ
Useful so that we don't have to run the hierarchical DC iDCT if there aren't
any coefficients.  Opens up some future opportunities for optimization as well.

19fb234e4a H.264: split luma dc idct out and implement MMX/SSE2 versions
About 2.5x the speed.

NOTE: the way that the asm code handles large qmuls is a bit suboptimal.
If x264-style dequant was used (separate shift and qmul values), it might
be possible to get some extra speed.

c988f97566 Rearchitecturing the stiched up goose part 1
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.

f6f7d15041 h264: don't touch H264Context->ref_count[] during MB decoding
The variable is copied to subsequent threads at the same time, so this
may cause wrong ref_count[] values to be copied to subsequent threads.

This bug was found using TSAN.
