b4c2ada528 Attempt to fix asm compilation failure. 
Only tested on gcc 4 & x86_64.

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:

085d9d98e8 Only calculate the second chroma qp if it differs from the firstin the main 
loop filter. (a little faster for the common case where they are equal)

76d81909ae Update libx264.c to use new libx264 features 
With b_keyframe instead of IDR for detecting keyframes, ffmpeg should now
support periodic encoding with periodic intra refresh (although there is no
interface option for it yet).
Set the new timebase values for full VFR input support.
Bump configure to check for API version 83.

c988f97566 Rearchitecturing the stiched up goose part 1 
Run loop filter per row instead of per MB, this also should make it
much easier to switch to per frame filtering and also doing so in a
seperate thread in the future if some volunteer wants to try.
Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample)
This change also allows some optimizations to be tried that would not have
been possible before.
