It is unacceptable that yvel is on one hand modifiable without restriction from
scripting, but can be used as an array index without prior bound check in the C
code. Because that member has an overloaded meaning and is also used for
innocuous purposes such as the green color intensity of an SE light, it's
infeasible to restrict access from scripting. Consequently, we must add bound
checks on the C side. This is the first part of the effort to make .yvel safe,
adding two functions P_Get() and P_GetP(). There are a couple of other uses as
some kind of index.

- factor out: G_WallSpriteDist()
- factor out: Proj_MaybeDamageCF() and Proj_MaybeDamageCF2()
in preparation for the next commit
- Make PROJ_DECAYVELOCITY macro take an arg for readability's sake

And 0 otherwise. Before accessing a sprite that is not not known to be
definitely valid (e.g. a loop over all sprites from 0 to MAXSPRITES-1),
one should check for validity before accessing it in any other fashion.

Also, add hitscan test to test.lua -- a crosshair-like sprite is spawned
and continuously updated to the position of where the player aims at.

It was only ever used as upper bound to the time that a visibility change
decays, but since it does that in an exponential fashion, there's really
no point.

- 'copy' may have them as source, 'getarraysize' works fine
- 'setarray' and 'resizearray' are obviously forbidden
- 'readarrayfromfile' and 'writearrayfromfile' is not implemented for them
(use case?)
Also, in the Makefile: don't use realpath on directories. It may give an empty
string.

- swap 2d and 3rd args in xmath.rotate() -- now rotate(point, ang, pivot)
- add vec3 method 'rotate', calling xmath.rotate
- store game tic count in savegames

- some renames of functions/methods
- con.actorvar: explicitly allow (for now) boolean and number values
- added gv.gametic, player.holdskey(), player.all(), actor.check*()/hit*(),
gv.rendmode, gv.REND, <bitint>:mask(), spr:getheightofs()
- make read of nil var in "finalized" (live) module produce error, too
- add test/helixspawner.lua

E.g. con.action{0, 4, delay=20}; for convenience, viewtype and incval are
initialized to 1 (not 0) here.

Using macros like AC_COUNT(t). Clean up related code:
- comment out the dead condition noted in the previous commit
- Lunatic: use get_count() instead of get_t_data(0) in one place,
rename to _get_t_data(), i.e. make that method internal

documentation for ps:padecol().
