It's time to replace some int32s with 64-bit ints in core engine functions.
The problem is that for example, the dot product is taken between vectors that
may be the difference between two arbitrary points in a sector, so even if one
sticks to the "no blue walls" rule, that doesn't guarantee freedom from
overflows.

Bang! One more invalid internals exposure squashed. Maybe one day we'll be able
to call EDuke32 "stable"...
Actually the offending sprite IS drawn as face sprite with shade 32 and xrepeat
and yrepeat 255 for the convenience of the CON coder who will have to debug it.

Those were happening when wall drawing in an upper/lower layer "closed" too
much of the "curtain" (umost/dmost) for subsequent drawing in that portal.
Example: looking down the sewer manhole at the beginning of Retaliation will
now render without HOM.

Also, correct the loadboard() return value checks in premap.c to be
aware of a returned -2 ("wrong map version").

This should be more correct, since previously, the saved PNGs were way too
contrasty when looked from within a browser. Now, they'll always be
slightly darker than in-game (assuming one has a gamma greater than 1).

- Make MAXXDIM and MAXYDIM macros be 860 and 490, respectively. tueidj says
max. screen size is 848x480, but there are oob access bugs in the classic
renderer when running with the maximum possible resolution
- don't allocate additional sector/wall storage for Mapster (saves ~16k)
- Add ud.config.UseJoystick = 1 in config.c, but make it conditional on Wii
- remove one comment I no longer believe true, add one TODO comment

Previously, we checked whether the faded palette has changed (by way of CRC)
and invalidated the textures then unless the preserve flags were set. This
however could lead to wrongly invalidating them under unfortunate circumstances,
e.g. basepal change from CON + tints at the same time before r2620 which
reverted r2232.
Now, only invalidate them if the corresponding preserve flags are clear AND
* the base palette has really changed OR
* the palette CRC changed and we were running on software gamma
The latter means that performance-killing invalidations may still happen on
GL platforms lacking HW gamma (for ATI, it's currently only disabled in 8-bit
fullscreen).
Also have a new global 'basepalreset' to fake a basepal change for
setbrightness(), currently used when changing renderers so that going from
Polymer to Polymost and back again will invalidate the Polymer textures
on the second change, potentially re-applying a basepal highpal. (Still
with me?)

Because gltexinvalidate*() could be called too often when setgamepalette is used
while having a tint overlaid else. Pending thorough analysis/reworking of the
32-bit mode base palette handling / texture invalidation.

Previously, we only set the viewingrange according to the physical screen's
dimensions, but didn't correct yxaspect for a potential non-square pixel
ratio.

- factor out many identical checks in a convenient function; some messages
may read slightly differently now and tile ranges may be handled more strictly
(error out if one of the limits is invalid)
- factor out two instances of identical (up to one arg) code into
tile_from_truecolpic
- factor out setting picsiz[] and stuff into set_picsizanm
- some checks
- Make "undefmodelof" non-functional and warn.
- in "animtilerange", if the tile difference is >= 64, error out since we
can't store it in picanm[]

This requires one tweak in drawrooms' umost/dmost setup to prevent oob access.
Specifically, a coordinate difference of 0 is allowed. In the classic renderer,
this would mean a one-pixel (real screen coords) height or width. In Polymost,
it would currently mean a one-pixel height and zero-pixel width, but this might
be subject to change.

(That is, the base shade table.) Before, we allocated each palookup buffer.
For a vanilla setup, this means that we're now saving 224*32*256 ~= 1.8 megs,
which might be interesting for low-memory gadgets.

First, it's unlikely in our day and age. Second, they're always free'd at the end,
so allocache'ing them is incorrect.

Also,
- use this in game.c and astub.c palookup loading code
- when makepalookup() is passed a 0 palnum, return early. This means that
'fogpal' will silently fail when attempting to change pal 0.
- in 'makepalookup' DEF command, error out if passed a pal of 0.

Alongside, these make into into the header:
- the 'tokenlist' type (a typedef'd struct)
- the T_EOF and T_ERROR enumeration values

- Help window text cleaned and made more consistent between game and editor
- Added help entry for "-clipmap"
- Log text for using CON, DEF, and RTS files has been made consistent
- All instances of '%s' have been replaced with \"%s\" because ' is a valid filename character. (At least on Windows.)

There are instances where oob picnums may propagate to that function, so
protect it. The digitanumber[z] bound check is actually made more permissive,
but could also just as well be removed now.

We shouldn't assume a particular bytes-per-line value and use ylookup[] instead.
Specifically, windowed modes on Windows use a frame buffer that always has odd
x dimension.

- in Mapster, pre-form the default 10 clip map names before returning from
G_CheckCommandLine() so it gets loaded even if we passed no cmdline args.
- malloc + strlen + strcpy --> strdup
- don't need to spank dead variables ;)
- we may call calloc with zero size, which isn't bad by itself, but asserting
for non-null afterwards is. Allocs of 0 are implementation-defined, and may
well return a null pointer (C99 7.20.3).

Gives a couple more fps for scenes where much screen estate is covered by
stuff, like when holding the devastator.

With the same setup as before, a screen-filling translucent wall (with nothing
drawn behind it) renders at about 7 fps faster (from 60-something fps initially)

These two functions draw a vertical line 4 neighboring pixels at a time.
This gives a significant speed boost for a full screen solid and masked wall
scene for x86_64 (where we have plenty of registers), about 60 --> 76 fps.
