Many functions have such a prefix, but do not actually use any
instructions or features from that set, thus giving the false
impression that swscale is highly optimized for a particular
system, whereas in reality it is not.

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.
