059715a41c First part of a series of speed-enchancing patches. 
This one sets up a snow.h and makes snow use the dsputil function pointer
framework to access the three functions that will be implemented in asm
in the other parts of the patchset.

27c61ac53d 8x8 integer dct from x264 as cmp function (under CONFIG_GPL) 
if this gives better quality then SATD then someone should port the x86 code too or maybe we could even just call it from libx264
the 4x4 one could be tried too ...
