Fixed bug 3816 - asm code in video/SDL_stretch.c

Sylvain

I propose this new version for SDL_stretch.c that drops mprotect and asm

Code is similar to the StretchLinear, but the steps computation are kept similar to the nearest.
so that:
- it's pixel perfect with nearest
- as fast as asm I think
- no asm, nor mprotect
- benefit for all archicture
