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.

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.

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.

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.
