More SciTech SNAP updates. Some of these files didn't really change, but

they show up in the list (GLU stuff) for some reason. The major change
here is the addition of code in the glx86asm.py file to generate assembler
stub entry points with the correct name decorations for _stdcall calling
conventions so this can be used on Windows boxes.
