This is a hair slower (0.15% maybe) but i really dont want to have the
identical code duplicated 3 times because gcc adds odd threaded jumps with
register reshuffling and register safe/restore.

980bcc554d Unroll main loop so the edge==0 case is seperate. 
This allows many things to be simplified away.
h264 decoder is overall 1% faster with a mbaff sample and
0.1% slower with the cathedral sample, probably because the slow loop
filter code must be loaded into the code cache for each first MB of each
row but isnt used for the following MBs.

87ac0c0a39 Use AVPALETTE_COUNT instead of hard-coding 256. 
This is consistent with other codecs and will also avoid a crash on the
memcpy to data[1] if AVPALETTE_SIZE ever increases.

ab8075a2da Remove redundant initialization of the palette, it is part of the context 
and that one is always 0-initialized already.

48c65d0dc9 Zero the frame data on allocation for VB codec, e.g. the FATE sample seems to 
rely on this.

e62a55b92e The SSSE3 version of dct_quantize in mpegvideo_mmx_template.c needs 
inv_zigzag_direct16 16-byte aligned, so mark it appropriately.
Fixes encoder crashes e.g. with MPlayer's -vf lavc.

258b60c224 Gcc idiocy fixes related to filter_mb_edge*. 
Change order of operands as gcc uses a hardcoded register per operand it seems
even for static functions
thus reducing unneeded moved (now functions try to pass the same argument in
the same spot).
Change signed int to unsigned int for array indexes as signed requires signed
extension while unsigned is free.
move the +52 up and merge it where it will end as a lea instruction, gcc always
splits the 52 out there turning the free +52 into an expensive one otherwise.
The changed code becomes a little faster.

1f445f5473 Move dquant check into qscale overflow check. 
This should be faster (couldnt meassue a difference), and its less picky
on slightly out of spec dquant.
