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.

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.

-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

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

The overall situation is thus as follows:
- in C and from Lua, that member is called 'fogpal'
- In CON (both C-CON and LunaCON), it's 'fogpal' with 'alignto' being an alias;
'filler' wasn't available before, either.
- In m32script, it's 'fogpal' or 'alignto' ('filler' is not available any more)

That is, if that member has a nonzero value, that one is taken for the color of
the GL fog instead of (most of the time) sector[].floorpal. "Sky sectors", that
is, skyboxes or simply parallaxed floors/ceilings are *not* handled.

This is done by factoring out some polymer.c:polymer_getbuildmaterial() code
into polymer_eligible_for_artmapping() and using that. The one in polymer.c
can still determine to not use ART mapping on some ("rare"?) occasions, so
it's not 100% in sync.

- move some auto vars further down

- Stop using memcache on some other failure paths, particularly when
failing to read from the on-disk texcache.
- Factor out cache reading code (3x).
- Fix endianness issues affecting big-enadian systems (one introduced by
r3382, one existing before). Comment each B_LITTLE32 with whether we're
converting from native to on-disk (little) endianness or back.

Implemented using GL_LINEAR fog. The only source of difference (besides the
obvious indexed vs. true color) should now be the distance constant, which
still had to be determined experimentally. Polymer implements this mode in
its fog fragment program part.
Parallaxed skies are always drawn with full visibility, I'm not sure if there
are any maps that expect otherwise.
Also, accidentally committed: factor out initialization code from
polymost_printext256() into gen_font_glyph_tex(), small game.c changes.

This also means that the "r_shadescale_unbounded 0" option will work
in Polymer (except on models).
