Vittorio Giovara 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.

Luca Barbato c003832883 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.

Diego Pettenò 7ad6469eae Convert asm keyword into __asm__.
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.
