can be initialized.

swscale: further cleanup swscale.c
Move x86-specific constants out of swscale.c
commit 86330b4c92

Date: Wed Apr 13 20:57:30 2011 +0200
swscale: partially move the arch specific code left
PPC and x86 code is split off from swscale_template.c. Lots of code is
still duplicated and should be removed later.
Again uniformize the init system to be more similar to the dsputil one.
Unset h*scale_fast in the x86 init in order to make the output
consistent with the previous status. Thanks to Josh for spotting it.
commit c003832883

swscale: move away x86 specific code from rgb2rgb
Keep only the plain C code in the main rgb2rgb.c and move the x86
specific optimizations to x86/rgb2rgb.c
Change the initialization pattern a little so some of it can be
factorized to behave more like dsputils.
Conflicts:
libswscale/rgb2rgb.c
libswscale/swscale_template.c
Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.

When built with gcc 4.6, the MMX rgb24 to yuv conversion gives
wrong output. The compiler produces this warning:
libswscale/swscale_template.c:1885:5: warning: use of memory input without lvalue in asm operand 4 is deprecated
Changing the memory operand to a register makes it work.

Don't change paramater passing, but instead use casts.
Shouldn't affect asm output on anything other than win64.
libswscale should work on win64 now.
The rest of ffmpeg still isn't win64 compatible due to the issue of xmm
clobbers, but swscale doesn't use any SSE.

long was being incorrectly used as an x86-sized register, both for 32 and 64
bits, but this is not the case in win64.

This is of course done with permissions from the authors. The only GPL
component left are MMX optimizations for YUV to RGB conversion.
