53d9264f92 Fix a couple of out-of-bounds accesses when roaming around with noclip.
- guard cansee() against negative sectnums (return 0 immediately), since
  it's often called with the player sectnum as one argument
- in resetpspritevars(), don't inset APLAYER sprite if sectnum < 0, which
  can happen if a map is started in void space accidentally (e.g. from
  the editor)
- two checks before accessing sector[] with a player sectnum

00b852fe37 EDuke32: When in menus, always draw a black (33%) translucent background.
Internally, there's a new function fade_screen_black() that implements the
fading more efficiently than calling rotatesprite for classic, and uses
tile 0 (assumed to have at least 64x32 size) in the GL modes.

The black background of the user map selector is still done with rotatesprite
and tile BLANK in every renderer.

a6158ac3f6 Fix building with GCC 4.6 link-time optimization.
It looks like GCC doesn't honor the 'used' attribute with LTO. This is
"fixed" by declaring the variables in question with external linkage
(i.e. removing the 'static').  I consider such behavior a GCC bug, though.

d0acd40ff8 Inreased debugging level for catching oob accesses to 'main' arrays.
If enabled, this makes the following arrays be allocated statically:
spriteext, spritesmooth, sector, wall, sprite, tsprite, while
necessarily disabling the clipshape feature (because it relies on
setting sector/wall to different malloc'd block temporarily).

To compile, pass DEBUGANYWAY=1 in addition to RELEASE=0 to 'make',
and it's really only useful with CC=clang, of course.

340b2f7647 Increase the number of maximum art files from 64 to 256 and tweak loadpics().
It is likely that this is the value it used to have at some point, because
the MAXTILEFILES macro equals 256 and is as old as the Duke3D source.
loadpics() now refuses to load an ART file with localtilestart or localtileend
out of bounds, or if localtileend<=localtilestart (i.e. no tiles in ART file, or
nonsense). Also, on 'invalid art file version', continue instead of returning.

Note: this does not increase the maximum number of tiles, which is still 15360,
it only gives a bit more freedom to arrange them (well, into more art files).
Also, I don't see what anyone keeps off from packing any number of tiles (from
1 to 15360) into an art file. Old EDITART limits?

480690aa1d Fix the Polymer hitches first encountered with Parkade.
The cause was a combination of many factors. First, Polymer requires the
start-drawing position to be inside the sector to draw (deviations lead to
incorrect drawing).  This was violated by the game, because it interpolated
the current and next tic position without updating the sectnum, leading to
inconsistencies especially when passing through narrow sectors.  Polymer
worked around it by doing an updatesector() each frame, however this works
poorly for maps with overlapping geometry such as SoS or RoR.

The solution to this is to add a new engine function,
updatesector_onlynextwalls(), which searches the sectors (via nextsector)
in breadth-first fashion instead of from 0 to numsectors-1, like updatesector
does when it fails for the *immediate* nextwall neighbors.

Internally, the breadt-first search helpers are moved into the engine.

8ec15480c0 Besides the performance issues, there's another reason why changing the palette
'frequently' isn't such a good idea.  Assume an actor constantly changes the
palette to some value and you're attacked by a newbeast at the same time. Then
the pain tinting would be reset each time the actor's code is run.  This commit
adds a new flag 16 to setbrightness(), meaning "don't reset the fade tinting".
Its only use right now is from CON's setgamepalette command (and there, always).
The change is done in the engine and thus affects all platforms.

8e54a3febf Preliminary commoning of actor[].t_data[10] to an array of int32's on both
32- and 64-bit platforms. Also, make struct type actor_t also have a common
size of 128 bytes. New code currently disabled and #ifdef'd for comparison.

This requires certain t_data[] entries ([1]: move ptr, [4]: action ptr and
[5]: ai ptr with actors) to be converted to script offsets instead of pointers,
breaking savegame and net packet compatibility (we could in theory try hard not
to, but it would be too much trouble).

2675334a60 In backing up highlighted sectors code: also back up TROR information so
that bunches and nextwall links are restores, too.  Now, to coalesce two
TROR maps (e.g. for a CBP), one could
  do for i allsectors, sethighlightsector i 1
on the console, and then load the 'other' map to copy over the contents
of the first, including all TROR stuff. Note that neither selecting
all sectors with RAlt, nor duplicating them with Insert would lead to
the desired effect (yet).

Internally,
 - yax_setbunch() now has different behavior for bunchnums -1, -2 and -3
   (it either clears the nextwalls or not)
 - build.c has a helper function free_n_ptrs(). This could be handy in
   other situations where many blocks of memory must be allocated
   consecutively and freed in case of failure

7582b86237 Add high-resolution timers C API for profiling. The functions are called
uint64_t gethiticks() and gethitickspersec().  For SDL 1.2, the timer
has the same resolution as getticks (1000 Hz). For Windows and SDL 1.3,
the resolution of the underlying perf-timers is used.  The only user of
these functions right now is some TROR on-screen debugging code.

Revert an earlier change regarding r_preview_mouseaim.  We can't do the
check because editstatus is set later.

2415b03c79 Support for drawing 'island sectors' for TROR/classic (and with limited
functionality, Polymost).

The new feature can be enabled/disabled with the 'r_tror_nomaskpass' cvar.

The basic idea is that when drawing lower or upper levels, a first pass
is performed that ignores all red walls for which the TROR nextwall link
'towards' the viewer arrives at a red wall.  Thus, in the worst case, there
can be up to twice as many rendering passes now (when it is discovered that
the no-mask-pass isn't different that what would be drawn with the ordinary
one, the latter is skipped, since we've already drawn all needed geometry).

Hovever, this kind of multi-pass splitting is only suitable for simple scenes,
like the upper subway in the TROR test map.  In particular, multiple islands
shouldn't 'see' each other.

Two issues are worth mentioning: first, care needs to be taken for translucent
ceilings or floors, since drawing them twice isn't the same as drawing them
once. This is done for classic, but not for Polymost.  Second, sprites (which
are always drawn _after_ the geometry for a given pass) are still clipped to
the geometry of the ordinary pass, resulting in their disappearance from
certain angles.

Additionaly, a change made it into this commit that fixes redundant collection
of sprites in TROR:classic/Polymost.
