5bff8590f3 Simplify compute_exp_strategy() by passing a pointer to all exponents and 
exponent strategies for a single channel to compute_exp_strategy_ch().
This allows for removal of the temporary pointer arrays.

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.

290fabc684 Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. 
Doesn't help speed as there isn't an asm implementation yet, but consistency
is a good thing.

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.

ca32f7f208 H.264: eliminate non-transposed scantable support. 
It was an ugly hack to begin with and didn't give any performance.

NOTE: this patch opens up some future simplifications to be made (such as
removing some of the scantables from H264Context) but doesn't take advantage
of them yet.

e3331706fc Fix design of the pad filter. 
Previously the pad filter just drawed borders in the surrounding of the input
without checking if this area was allocated or writeable. Now we check and
allocate a new buffer if the input is unsuitable.
