1. Using an ART tile
2. Using a hightile defined through the tilefromtexture "texture" subtoken
3. Using a hightile that, if downsized, will be smaller than the ART tile for that tilenum (tenuous)

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.

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 ‘;’ or explicit braces around empty body in ‘for’ statement" with GCC 4.2, which is important for old OS X versions.

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.

-Sort by owner now occurs only when two sprites have matching x/y coordinates.
-Cstat 1024 now activates a special drawing mode that indicates a sprite should be drawn without depth after all other sprites have been drawn. The previous cstat 1024 functionality, an internal hack for shadows cast by models in Polymost, has been moved to bit 1 of a new graphical effects bitfield stored in a tsprite's .extra member.

This prevents an oob access when rendering, the one observed was at
polymer.c:4255.

0 - Multiply
64 - Screen
128 - Overlay
192 - Hard Light
Note: These will likely look terrible when combined with the Colorize flag, because of the nature of the Colorize flag.

-faketilesiz[MAXTILES] removed in favor of simple faketile[(MAXTILES+7)>>3] bitfield
-h_xsize/h_ysize (tile size overrides from .def) are now uint16_t instead of int32_t
-hudmem[2][MAXTILES] removed in favor of adding a hudmem ptr to mdmodel_t
-tilefromtexture performance improvements
-more tsectortype/twalltype usage in various engine functions that read but never write
-continued Polymost cleanups and refactors. Please report any odd rendering errors.

-lots of stylistic rewrites
-further improvements to anti-fighting code for wall and floor sprites (introduces three new cvars, r_wspr_offset, r_wspr_offset_variance, and r_fspr_offset)
-fixed brief HOM when traversing through a one-way masked wall
-seldomly used "alphahack" feature for hightile textures now represents alpha cutoff internally as a single byte instead of a float
-fixes a handful of issues where geometry failed to draw at certain coordinates from certain angles in certain resolutions
-renames a couple of cvars

This prevents a enormous leak being reported by LeakSanitizer. Not that it
matters much, since we most frequently free models only at exit. (Sometimes one
may be freed earlier though -- if there was an error loading it, AFAICS.)
