7d87d56ff8 Take advantage of per-channel exponent and exponent strategy layout to 
simplify and speed up encode_exponents().
8% faster in function.

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.

0429e4a6ca Move exp_strategy from AC3Block to AC3EncodeContext in order to arrange by

7cc4be58b4 Rearrange exponent buffer to group all blocks for a single channel together. 
This will allow for faster and simpler processing of all blocks at once.

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.

no longer exists.

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.
