0c32e19d58 Move +52 from the loop filter to the alpha/beta offsets in the context. 
This should fix a segfault, also it might be faster on systems where the
+52 wasnt free.

1cc2d21175 Set edges based on cbp and mv partitioning, not just skiped 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.

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.

68cf92ee5e Always call avcodec_thread_init() 
The various avcodec_thread_init() functions are updated to return
immediately after setting avctx->thread_count.  This allows -threads 0
to pass through to codecs.  It also simplifies the usage for apps
using libavcodec.

92c6a099ba H264 DXVA2 implementation 
It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under
VISTA and Windows 7).
 It is implemented by using AVHWAccel API. It has been tested successfully
for some time in VLC using an nvidia card on Windows 7.

 To compile it, you need to have the system header dxva2api.h (either from
microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h)
 The generated libavcodec.dll does not depend directly on any new lib as
the necessary objects are given by the application using FFmpeg.

5e7dfb7de1 Move COPY3_IF_LT to lavc/mathops.h 
This obscure macro is only used in motion_est.c so having it in lavc
makes more sense.  See discussion here:
