With this change, it is impossible for negative values to be used as array
indices inside this function, and I believe that it is also impossible that
they escape to somewhere they might be used as such.
For Lunatic, allow setting actor[].picnum to negative values and in the
translator, add (commented out) code to warn whenever it is set to a constant
negative value. Also, fix a _sound call in _addphealth in control.lua.

While the functionality was already internally in place for gametext as one of two hacks using ROTATESPRITE_MAX (the other still used by minitext_() to align with the statusbar) we must codify a bit in the engine for safe external use. (Otherwise, ROTATESPRITE_MAX could/would theoretically increase and leave modders high and dry.)
(Dev note: In G_DrawTXDigiNumZ(), ROTATESPRITE_MAX was used to bitshift the value used to calculate digit spacing for no reason I can ascertain other than to introduce rounding errors into the zoom/textscale calculations. It was never used anywhere, so I removed it.)
Bonus: The scaling code for digitalnumberz and gametextz has been modified so that the spacing is no longer affected by rounding errors. Try animating the zoom value and compare how the text used to jump but now does not.

There's only one RETURN value on the C side (g_RETURN), which is also referenced
from Lua. Upon entering an event, its value takes on the per-event default one,
and its value when the event code finishes is passed back to the game.
Independently of that, its value is always saved and restored across event calls.

(Or '0's, but that case is handled automatically.) The resulting generated

Toggling whether a getactorvar for a global or per-player gamevar issues

Also update test/dangling_else.con. See there for how if* cascades are handled

- add LuaJIT's 'v' module printing trace info
- translator: fix game function name definitions
- revert math.fmod -> math.modf, they are different!
- disable JIT compilation for a function we're getting strange crashes with
- Make some of DukePlayer_t's members 'bool' on the Lua side. It's way
too easy to write something like "ps.jetpack_on" where "ps.jetpack_on~=0"
was meant. [Background: Kyle873 observed that Duke was always floating.]
- Error out if looping in our_module(). I find this behavior more logical
than returning true.
- fix a couple of missed FORBID variables

Previously, actor[].shootzvel (implementation detail, not available to CON)
was checked, and if it was !=0, that was the overridden velocity. The value
0 meant "hardcoded, projectile-dependent velocity". But that neccesiated a
hack where if zvel 0 was passed and really meant, it needed to be set to
1 instead. Now we have A_ShootWithZvel() taking an additional last argument
plus a macro SHOOT_HARDCODED_ZVEL permissible for that argument.

actors.h: remove 'packed' from projectile_t, tiledata_t. In tiledata_t,
make .cacherange member an int32_t so that the following member
"projectile_t defproj" is aligned on a 4-byte boundary.

Most of them are already aligned to their natural boundaries, so lowering
the alignment to 1 byte can only worsen things by making the C compiler
generate poorer (unaligned access) code for some platforms.
The layout of structures is not specified by the C Standard, but is rather
given by a particular platform + toolchain's ABI (application binary interface).
Most ABIs follow the expected pattern "alignment of scalars is their size,
alignment of arrays is that of its element type, alignment of structs is the
maximum alignment of its members". A couple of links to particular ABIs are
given in build.h.
Problems are expected with archs that care about unaligned access when a pointer
to a non-packed struct is taken that resides in a packed aggregate, but these
uses should be weeded out (I'm not sure if there are any in our codebase).
The following types are affected, only hitdata_t changes its size:
sectortype, walltype, spritetype, spriteext_t, spritesmooth_t,
struct validmode_t, picanm_t, palette_t, vec2_t, vec3_t, hitdata_t.
