swscale: simplify rgb2rgb templating
MMX is always built. Drop the ifdefs
commit 33a0421bbaa64f4e9c3d852b7f225ede8dad1388

swscale: simplify initialization code
Simplify the fallthrough case when no accelerated functions
can be initialized.
commit 735bf1951171a1e0ee4292e84a1b1beac45dd0ab

swscale: further cleanup swscale.c
Move x86-specific constants out of swscale.c
commit 86330b4c9258d5e583c0db033d1e68f46443307c
Author: Luca Barbato <lu_zero@gentoo.org>
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 c0038328830d7b341c28d7c99b0236a33617fd21
Author: Luca Barbato <lu_zero@gentoo.org>
Date: Wed Apr 13 20:57:29 2011 +0200
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.
