Init simplification and 2% faster wma_decode_block on amd64 with tables use
instead of pow(). (by banan)

the init simplifictaion is not correct its not binary identical
the pow optimization breaks decoding of http://klif-e.mos.net.au/videos/extr.wmv

d59518d45d since Michael prefers to keep dsputil.h private to libavcodec 
(rather than installing it system-wide) this patch reverses the

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.

56419683b2 I still don't think this should be here. Note: without this code DV encoder 
will accept incorrect pix_fmt's and such, but decoder will work much better
with containers not setting the same attributes. It seems like there will
be a generic mechanism for checking such constraints, but if not I can always
resurrect this check for *encoder* only.

79a32e3b95 64bit fixes for the tta decoder, sizeof(long) is 8 on amd64, 4 on x86, the patch 
basicly just do a s/long/int32_t/. Patch tested on amd64 and x86.

e5867e4d50 Not that we're that far from being an *initial* implementation, but 
at least weighting got implemented thanks to Dan. ;-)

2e52b44e50 AC coefficient weighing (per SMPTE 314M) for the DV encoder and decoder. The 
performance impact is less than 1%.

6df5f6ae51 size[0-3] are not initialized (and can get random negative trash 
values), so the comparison with vs_total_ac_bits is messed up on the
first couple loop iterations, leading to AC underflows.

the b->prev[] pointers were not being maintained correctly. We
potentially have to update b->prev[] both before and after the area
whose VLC length is getting adjusted.

this also might fix the ppc regression failure?
