Init simplification and 2% faster wma_decode_block on amd64 with tables use

d59518d45d since Michael prefers to keep dsputil.h private to libavcodec 
(rather than installing it system-wide) this patch reverses the
mistake I made last month (mplayer was recently fixed accordingly).

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.
