This directly achieves the following:
* Eliminated codedup.
* Recently introduced GL ES performance downsampling now applies to model skins.
* Replaces the alpha/art format distinction with {RGB/no alpha, RGBA/one-bit alpha (ART transparency), RGBA/full alpha}.
* Cleanly allows multiple fallback formats for each type.
* Ready for further commits.

a35f3b13dc Replace the semicolon trailing empty-bodied loops with opening and closing braces. 
I believe this is the clearest way to indicate that an empty-bodied loop is intended, as opposed to the possibility of a mistaken semicolon.

This eliminates "warning: suggest a space before β€˜;’ or explicit braces around empty body in β€˜for’ statement" with GCC 4.2, which is important for old OS X versions.

e00115c043 Introduce USE_GLEXT macro and use it to conditionally compile out all GL ARB function calls when compiling for GL ES platforms. 
This replaces the previous hack where we kept the dynamic pointers null and simply never tried calling any of them by a conspiracy of default runtime settings and disabled menu options.

Code affected: VBO support for models, VPX GLSL decoding, texture compression (texture cache), and multitexturing (glow/detail maps).

This commit also replaces EDUKE32_GLES conditionals with USE_GLEXT where appropriate.

I didn't touch polymer.c because it depends too heavily on extensions for conditionally compiling them to make sense.
