fc1eda543c swscale: fix sign extensions in yuv planar conversion
Casting the left-most byte to unsigned avoids an undefined
result of the shift by 24 if bit 7 is set.

yuvPlanartouyvy_c and yuvPlanartoyuy2_c are affected.

to ensure that anyone using this (non public) function doesnt end
with hard to debug crashes. The new name also has a proper prefix.

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.

	New Revision: 28996

	Log:
	Fix libswscale compilation on non-x86, hopefully without breaking MinGW64 again.

This change was non optimal, correct would have been to revert the offending commits
if no time was available to find a clean fix.
