b38d487466 New implementation of rgb32tobgr32 
The previous implementation segfaulted with MMX enabled when fed an image
smaller than the size of the units the MMX code processed. The new code:
- is faster for MMX, MMX2 and plain C
- processes small images correctly
- is LGPL

df170b81d9 Remove code duplication in sws_rgb2rgb_init. 
The lists of assignments of all rgbxtoy variants are removed from
sws_rgb2rgb_init and replaced by a single list inside the template file.
This way, multiple lists are generated by the preprocessor and each list
gets its own initialization function. Those are called from the main
sws_rgb2rgb_init function, if applicable.
