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.

4693b031a3 Move H264 dsputil functions into their own struct 
This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.

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.
