Removed use of LUT16to32 in HQx asm versions, replacing some MMX code with 'plain' x86 code. Advantage: got rid of a 256kb table (reduces cache load, so over here the code is about as fast as before; in particular, since the affected interpolators are not used that often, it seems). Moreover, the new code is more accurate than the old ASM code, which actually differed from what our C++ HQx did (sacrificing precision for speed, i.e., cheating ;-)

Implemented the OSystem framebuffer API, as discussed on scummvm-devel. All changes are just fine, and won't cause any compile problems or regressions, despite the fact that I can't test most of the non-SDL backend changes, at an improbability level of two to the power of two hundred and seventy-six thousand to one against - possibly much higher. Anything you still can't cope with is therefore your own problem. Please relax.
