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.

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

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.

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.

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

- Use 4 spaces throughout for indentation;
- Fix inconsistent indentation;
- Indent function calls and declarations aligning arguments on multiple lines
to the column after the opening parentheses;
- Align asm code to the column 4 spaces after the call to __asm__();
- Align cases in switch statements to the same column as "switch".

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.

It seems that binutils >= 2.18 just treat eax as rax but older versions fail.

Neither the asm() nor the __asm__() keyword is not part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).
Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 synta.
