swscale/rgb : move shuffle func shuffle_bytes_1230, shuffle_bytes_3012, shuffle_bytes_3210 in order to add SIMD

Libav, for some reason, merged this as a public API function. This will
aid in future merges.

A define is left for backwards compat, just in case some person
used it, since it is in a public header.

The function is specific to little endian

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

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 macro has unconditionally used .p2align for a long time and
serves no useful purpose.

Introduce and use COMPILE_TEMPLATE_* instead.
