- 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

Note: in polymer.c, this was buggy (but harmless) because .r is a char:
if ((uint32_t)hictinting[MAXPALOOKUPS-1].r & 0xFFFFFF00) != 0xFFFFFF00)

Specifically, the handling of one-way walls ([1] in Mapster32) was slightly
different.

Mostly, these are rendering-related variables. We keep *writing* them to
mapster32.cfg so that older Mapster32 versions can be used side-by-side
for now.

This mode does not take a sector's visibility values into account for uniform
darkening of a texture. It is more faithful to classic with respect to
fog/visibility *distances*, but may be less so as far as the "tint" of the
texture due to visibility attenuation is concerned.

That is, for every for palette (now, even ones created by the user) the last
shade is the (or rather, a color close to the) full fog color by construction.
In loadpalette(), reject a PALETTE.DAT with only one shade level.

Concretely, for all 1 <= i <= 255, make graypalookup[31][i] := graypalookup[31][0].
Also document 'fogpal' in the Lunatic doc.

Also,
- add a static assertion to engine.c
- gameexec.c: compile out an unused function in Lunatic builds

This makes the game not process as many ticks as have elapsed during the saving
afterwards.

The extended PALETTE.DAT format can now carry a trailing byte, called
'lognumalphatables'. If it is present, the engine assumes that alpha blending
tables are loaded at blend indices 1 to 1<<lognumalphatables and handles
rotatesprite's alpha and spriteext[].alpha accordingly.
The ability to save this new byte is added to engine.lua:savePaletteDat()
and the corresponding convenience functions in shadexfog.lua.
Examples test/screentext.con and test/sprite_access.con are updated for
demonstration purposes.

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.

Also, extend the documentation for r_usenewshading a little. Specifically,
note when the different modes were introduced. BUILD_LUNATIC.

It was plainly noticeable in the editor's tile info display, for
example.

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.

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