We normally enable backface culling always, but turn it off for
two-sided sprites; we need to make sure it's re-enabled after that
as sector masks are drawn after.

Some of the ROR code was operating under the assumption that drawasks
always correspond to one call of polymer_displarooms(), but that's not
necessarily the case; external view draws all sectors from the top
polymer_drawrooms(), which was causing crashes. Just ignore the sector
mask queues in external view mode, we already don't draw masked walls.

Check all the bunch siblings if we get a floor/ceiling hit and walk
them if their own planes hit.

When walking the sectors in displayrooms, detect floor/sector masks to
place them in a mask queue. The queues are allocated on the heap, but
a stack pointer is maintained by the displayrooms to allow it to play
nice with mirror recursion.
Right now the masks are drawn after all of drawmasks is finished; that
means you can see sprites and wall masks through sector masks, but not
the opposite. There is a slight attempt at blending far to near, but
nothing too conclusive yet; that means that in some cases some sector
masks won't be visible through other sector masks, but it should work
for trivial cases.
The next step would be to copy all the drawmasks logic into Polymer
and have it (attempt to) properly interleave sector masks where they
belong in the blending order.

Previously they would get counted both as 1-way walls for immediate
drawing and as mask walls for delayed drawing.

Assigns the right alpha value to floor/ceiling planes if their
translucency bits are set and make sure that changing the cstat now
triggers an update of the material for editing purposes.
This doesn't do anything by itself, but will be needed to correctly
draw floor/ceiling masks.

When walking the sectors, put more drawing work between queuing and
reaping the occlusion queries to potentially make them more efficient.

Enumerate the vertical siblings of each walked sector and check them
against the current frustum. No occlusion queries yet, but that should
correct any missing sectors until a flaw in that logic is discovered.

- slight tweak to the loading screen fadein/out timing
- two bound checks
- make some variables static in engine.c

which switches have been hidden in the original and user maps. One is to make
it face a wall, and another is to 'embed' it in e.g. the floor, like the
monitor with the burning fuse in E4L1. Both kinds show up when the switches
are rendered as models, revealing the secrets that the mapper sought to hide.
My proposal, implemented in this commit, is to apply a heuristic for such
switches at premap and make them invisible (set cstat bit 32768). The
conditions are re-checked during the game in case there is a switch coming
out of the floor, for example. A new spriteext bit is used for this feature.

The two bugs are:
- RPG projectiles don't pass through water
- can't emerge from slime in bobsp2
* Coalesce Polymer lights that are at the same position for FIRE-like sprites so that only one light is actually generated. This is good for usermaps that have multi-sprite fires, like bobsp2 again.

* fix breaking out of 'switch' blocks and compilation of the 'default' case
* Have a way of assigning 'special function' menu [' F] entries to script states. Writing a string literal after the state name will register the state under that name. Menu names are limited to 24 characters and it's possible to have up to 16 of them.
* new branching command 'ifinteractive', true if a state runs from the menu mentioned above.
* new command: getnumberfromuser <<retvar>> "query_string" <maxnum> <flags>
See 'state collect_teleporting_sectors' in a.m32 for a combined usage of the new functionality.

* helper feature: when shade preview is enabled, the ceilings and floors of highlighted sectors are shown in pal 6. This makes it possible to highlight the TROR-joining candidate sectors in 3D mode using e.g. 'sethighlightsector searchsector 1' while aiming at the respective ceilings and floors, and get visual feedback.
* when failing TROR-joining early ('no consistent joining combinations found'), print to the console why it failed.
* more Makefile.deps updating

* New shade/visibility calculation code, which is activated with 'r_usenewshading' (on by default), and is closer to the classic look. Also tweak the FOGSCALE macro to have approximately the same fog distance with all renderers.
* Mapster32: END modifier to RShift. If it's pressed when RShift is released, sprites which are in grayed out sectors are also selected; Make changing shade affect all highlighted sprites in 3D mode (when aiming at one of them).
* some debug code to watch out for suspicious glGenTexture/glDeleteTextures calls, not active.

First, it is now possible to disable the memcache (which is there to cache the texcache) by setting the new cvar 'r_memcache' to 0. Do this if you're constrained on memory or getting crashes when e.g. doing vidrestart often. Also, the memcache will disable itself (and free its storage, if it's there) the first time it fails to allocate.
Fix a strcpy with identical arguments in game.c and a couple of uninitialized mem accesses related to Polymer lights.
