    swscale: simplify rgb2rgb templating

    MMX is always built. Drop the ifdefs

commit 33a0421bba
Author: Josh Allmann <joshua.allmann@gmail.com>
Date:   Wed Apr 13 20:57:32 2011 +0200

    swscale: simplify initialization code

    Simplify the fallthrough case when no accelerated functions
    can be initialized.

commit 735bf19511
Author: Josh Allmann <joshua.allmann@gmail.com>
Date:   Wed Apr 13 20:57:31 2011 +0200

    swscale: further cleanup swscale.c

    Move x86-specific constants out of swscale.c

commit 86330b4c92
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 c003832883
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.
