735bf19511 swscale: further cleanup swscale.c
Move x86-specific constants out of swscale.c

86330b4c92 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.

0e1a5434e2 swscale: Factorize FAST_BGR2YV12 definition.
It is used only for x86 so it will eventually be moved with that code
into the x86 arch subdirectory.

long was being incorrectly used as an x86-sized register, both for 32 and 64
