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 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.

This fixes the remaining issue with WWII GI's LOGO.ANM: Color index #255 is used as the dominant white color (not as a transparent index) and fixtransparency() was mangling the image as a result.

-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

When that mode is enabled (see below for caveats), wall textures that have a
non-power-of-two height (call it 'h') will be modified to look like in classic:
Let 'H' be the next power of two greater than 'h'. The texture will be uploaded
with height 'H', made up from 'h' hlines of the original texture, followed by
'H'-'h' first hlines of the same.
No panning "corrections" will take place. The mode is disabled by default.
Caveats/notes:
* the mode requires that r_hightile is disabled
* it is not implemented in Polymer
* in the Lunatic build, it is ineffective when a VX map is loaded, as those
display walls with NPOT height textures correctly

... and cull code that is dead with the X*alloc() versions since they never
return NULL on requesting memory.
Use something like
git grep '[^Xx]\(m\|c\|re\)alloc *('
and
git grep '[^Xx]strdup *('
to see places where I left the B*alloc() calls intact.

- in mdloadskin() and gloadtile_hi(), use new function check_nonpow2()
(bit-twiddling) instead of loop
- Replace a couple of missed literals with CACHEAD_* enum labels

- factor out eligible_for_tileshades()
- remove some rendmode 1 code
- move some auto vars further down

The leak happened because a struct was hashed that had uninitialized
bytes in padding inserted by the compiler. The hash string in now constructed
as concatenation of three CRC32s as 8-byte hex strings, i.e. the individual
CRC32s are padded with leading zeros.
Note to users: because of the hash change, it's sensible to delete the
'textures' and 'textures.cache' files.
