uhypsq calculates the hypotenuse using unsigned multiplication. This is
permissible since for arbitrary int32s a and b, the following holds in
two's complement arithmetic:
(int32_t)((uint32_t)a * b) == (int32_t)((int64_t)a * b)
("Signed and unsigned multiplication is the same on the bit level.")
This fixes various overflows where wall lengths for walls of length > 46340
are calculated, but does not rid us of other overflows in the same vein
(usually dot products between vectors where one point is a wall vertex and
the other a position in a sector).

NAM and Napalm can now share their con, def, and rts files if the one for their respective game is not present because the con and rts files are identical.
Also, decapitalize two string literals missed in r2540.

EVENT_SOUND: triggered upon playback of any sound, this allows the "hard coded" sounds to be altered in a context-aware fashion instead of having to resort to clunky hacks like replacing them with a blank sound effect. RETURN var
iable is set to the sound effect # of the sound to be played, or -1 to cancel playback.
EVENT_CHECKTOUCHDAMAGE: triggered in P_CheckTouchDamage() whenever the player collides with anything. Value of RET
URN is set to the result provided by clipmove() and so can be decoded in the same way. Value of RETURN when the event is over can also be manipulated to control some of the hard coded damage effects.
EVENT_CHECKFLOORDAMAGE: triggered in P_CheckFloorDamage(), RETURN is simply the picnum of the floor of the sector t
he player is in. Can be used to cancel hard coded floor damage effects or to make other tiles exhibit the same eff
ects
Other misc fixes and cleanups, including a possible workaround for Duke Plus SECTOREFFECTOR light issues wherein all SE49 and SE50 that have a statnum of STAT_EFFECTOR are simply changed to STAT_LIGHT during the STAT_EFFECTOR loop
now.

This is so that it may be intercepted in the future.
The only code that's not replaced by the function call is with the CON
interface to g_player[].ps->pals via player[].pals X and .pals_time.
Also, comment out one instance because it's overwritten by a succeeding one.

This might now be even more confusing for users reading both the source
and CON code (where the access is necessarily still via '.clipping'),
but at least reading the source now makes sense :P

Ideally, we would also warn when setting WEAPONx_SHOOTS to negative values, but
we'd have to intercept CON's setvar's and it wouldn't be pretty.

to negative numbers. Previously, only checks for being zero were performed,
but CON code in the wild also has WEAPONx_SPAWN -1, which would propagate to
the sprite picnum...

TROR portals that works with a little help from updatesectorz() (change not visible
from CON code). Relies only on the presence of an extension whose portal isn't
blocked and also plays nicely with corner cases like being shrunk and enabling
the jetpack. This should fix the upward moving platforms in WGR2.

* rudimentary TROR support
* free mixing of multi- and single-tile pskies
* Don't cull models behind you. That is, treat them like floor sprites in that respect. This way large models like corpses don't disappear from the view unexpectedly.
Classic:
* tweak the last row and column of the translucency table so that e.g. a transparent sprite against a FANSPRITE wall doesn't show up purple (only if Duke3D table is found)
Misc.:
* fixes TROR-nextwall corruption when deleting sectors
* tile selector 'goto' now has also completion
* I forgot a file for the non-OpenGL build last time
git-svn-id: https://svn.eduke32.com/eduke32@1892 1a8010ca-5511-0410-912e-c29ae57300e0
* support for free mixing of multi- and single-tile parallaxed skies in classic
* make visibility independent of yxaspect and viewingrange in OpenGL modes
-- editor:
* when dragging walls, restore pixel width after that (only for the left and right walls of pointhighlight, and its nextwalls, if any)
* pasting on walls and auto-aligning them now carries over a few more fields
-- fixes:
* visibility in OpenGL modes wasn't incremented gradually (regression due to making 'clamp' an inline function instead of a macro)
* memory corruption due to calling qlz_compress with less than the recommended surplus storage of 400 bytes
* decorative sprites in the mirror showing non-flipped
* make the subway SE message (much) more helpful by showing which sector the game considers to be the track sector
