analysis of which side effects allowing a sprite highlight and a line highlight

Redundant for the same reason as the preceding one: the pointer has already
been dereferenced at the point the check is made. Also, all 5 calls of that
function pass a valid pointer (provided the pointers from which the expressions
are derived are valid). Reported by Stack, too.

The check is dead because it is made after the fact (oob access), but the
cheat string matching logic below actually assures that
cheatbuflen < sizeof(cheatbuf) at all times.

Also, in gamedef.c's definecheat handling, print the string length (19), not

Clang's UBSan reports this as undefined behavior. I think that the reason
is as follows: C99 6.5.3.2#1 (Constraints) says:
The operand of the unary & operator shall be either a function designator, the
result of a [] or unary * operator, or an lvalue that designates an object that
is not a bit-field and is not declared with the register storage-class specifier.
But in case of an expression like "&array[-1]", the operand ("array[-1]") does
not designate a valid object.
Moral: check first -- assure that an expression is valid for a particular
operation before carrying it out. Keep in mind that otherwise, the compiler
is absolutely free to optimize out the *check*.

- Rename sky_t members: yscale -> horizfrac, bits -> lognumtiles.
- Add default sky (8 tiles, horizfrac=32768 (i.e. 1/2 the scene horiz), offsets
all zero) and CLOUDYOCEAN sky (8 tiles, horizfrac=65536, offsets all zero)
to multipsky[].
- Get rid of "psky_t g_psky", merely maintaining a g_pskyidx instead. Set it up
at map load time so as to keep the behavior of the legacy per-map psky:
the last sector index with a matching psky ceiling wins.
- In mapstate_t, save g_pskyidx too, not (former) pskybits and pskyoffs[].
- Make on-map-load global psky setup consistent for the game and editor by
factoring it out into common.c: G_SetupGlobalPsky().
- Remove a couple of useless initializations, add some static assertions.
This commit is more likely to introduce subtle differences in behavior.
Specifically, getpsky() now always returns the default sky properties instead of
the global sky ones (but with all-zero offsets) when no match for a suiting
multi-psky is found. This is only likely to affect the yscale/horizfrac of
non-multi-pskies when a global non-default multi-psky has been set up.

- New function: MultiPsky_TileToIdx().

- Lower MAXPSKYTILES to 8 to reflect current usage (was 256).
- Game: make multi-pskies consider dynamically-remapped MOONSKY1, BIGORBIT1

The commit revises the definition of qstrdim when TEXT_[XY]OFFSETZERO are used. With these flags, the offsets the user specifies are now the only dimensions the function cares about in terms of tile placement, so depending on the difference between the offset(s) and the size of the final tile, it may be slightly more or less than the dimensions actually displayed on the screen because tile size is never taken into account. (For example, if your font is nominally 9x7 like the Duke bluefont and you use a TEXT_XOFFSETZERO of 5 with a string five characters long, the total x dimension will be 25 even though the last character will overhang that amount by four pixels. If you use a TEXT_XOFFSETZERO of 12 with the same string, the total x width will be 60 even though there will be three pixels of empty space on the right edge.) This change was made because assigning text an arbitrary constant width in general implies an intent to keep character positions constant even with a variable width font, but returning the visible span of pixels on the screen that the tiles cover would have caused the string to move when alignment options other than the top-left were used. In other words, you can now safely use TEXT_[XY]OFFSETZERO with the alignment options and the text won't jiggle.
Also, with TEXT_GAMETEXTNUMHACK, numerals are now effectively TEXT_XOFFSETZERO text that respect the above paragraph, so number count displays can look nice with alignment options too.
Having to modify the extent/offset code makes me realize that I'm not quite happy with its structure because it gets tangled juggling different concepts like character width, X offset, and spacing, and how they relate when the line wraps or in terms of the final size. Fortunately, it produces correct results as far as I know, and it's not necessarily ugly, just hard to understand. Handle with care.

encountered during post-load, an attempt is made first to assign it a sector

map. The background is that a dozen of maps do come with such sprites and
could previously corrupt the sprite list when loaded.

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.

- Make _buildargv[_buildargc] NULL.
- With SDL layer, pass argv and argc directly and get rid of _build* ones.
- Add tilesiz* to dynsymlists.

(Or '0's, but that case is handled automatically.) The resulting generated
number is taken by looking at the 8 lower nibbles and interpreting them as
a signed 32-bit integer.
Also add some number parsing tests to test/nlcf_break.con.

Toggling whether a getactorvar for a global or per-player gamevar issues
a warning or a hard error, the latter being the default.
Also, make it possible to readgamevar/savegamevar per-actor gamevars and
add userdefs member "idplayers" (read-only).

The first transformation makes the "control structure too long" error appear
only with larger if/else cascades, though it's still possible.

The only operation for which proper code is generated is reading a single value
from a system gamearray.

Also,
- an optimization for sprite[]:setpos(). Calls to get_sprite_index()
seem to be pretty slow (at least when they're not compiled).
- add getzrange to the dynsymlists

Fix 'setsprite' and 'music'. A good timing test for actors performance is
the starfield of WGR2's E1L1 ("Nexus").

This should have no adverse effects or side-effects. The changes only apply if a modder chose to use completely broken functionality in the first place.

All non-option positional arguments after an @ sign are taken as list files:
hashes at the beginning of a line denote comments, truly empty lines are
ignored, all other lines should contain one root CON file name.

glass at the beginning of the DukePlus map.

Instead of those of the translated code. Also some codegen tweaks and fixes.

Also update test/dangling_else.con. See there for how if* cascades are handled
in CON. It's actually kind of pretty. Also, take care to handle code deferred
to after the if/if-else properly (ifpdistl, ifpdistg, ifcanseetartet).

- 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

Notes:
- MAXJOYBUTTONS is out of sync between the two definitions
- In menus.c, NUMMOUSEFUNCTIONS must equal MAXMOUSEBUTTONS,
fail to compile if this becomes false.

This fixes an update issue: start EDuke32 without warping to a map in Polymost,
change to classic, and change to Polymost again. The OSD background will be
displaced.

We must not call these functions using the FFI, since the Lua state is
considered locked across such calls.

- some more outer commands
- gamearray persistence
- faster 'mod': use math.modf instead of math.fmod (the former is JIT-compiled)
- checkavail*
- THISACTOR special handling
- Fix building in Windows (export A_ShootWithZvel instead of A_Shoot).

Thus making the identical source and destination quote number case into the
expected no-op instead of being undefined behavior.

If m32script gamevar "move_by_one" is nonzero, the some keys move the
"player arrow" by increments of 1:
- Without SHIFT: LEFT/RIGHT absolute x, DOWN/UP absolute y, A/Z absolute z.
- With SHIFT: DOWN/UP (unbounded!) horiz, LEFT/RIGHT angle.
This can be useful to debug renderer bugs that show a high sensitivity to the
exact location ("are transient in space").

Face- and wall-aligned sprites are drawn using the wall routines in BUILD.
However, the per-x-screen-coordinate distance (swall[]) is calculated in a way
that potentially incurs great precision loss (for example 5 bits for
xdimen=1280, yxaspect=65536). This leads to the starting (top) vertical texture
coordinate possibly wrapping to large values, leaving an unsightly "stray line"
on top of the sprite from certain viewing angles/horiz values.
The approach to fix it has two parts: first, the distance is calculated using
float values, preventing the precision loss. Because this doesn't fully prevent
the unwanted lines, the texture coords are clamped to the mininum and maximum
(0 and UINT32_MAX respectively) when calculating them for sprites.
Note that stray lines may still appear at the *bottom* of sprites under certain
circumstances, for example when viewing at a y-flipped sprite from above.
These should be less noticable in real-world usage though.
The feature is guarded by a macro HIGH_PRECISION_SPRITE in case using floating
point or 64-bit integers is undesirable/impossible on some platforms.
