Currently syntax only. Parses the original scandcode 0x1d files, which is
harder than you'd imagine given the relatively simple structure. Chokes on
new-gen custom stuff.

If one next instruction happened to be interpreted, madness would ensue,
because the pointer wouldn't be aligned on the "opcode" part anymore.
Also, with "seti", set current sprite index only after a successful validation.

This get into the writable variable the "linking type" of the sprite with index
<spritenum>. The result is a bit field of ORed values:
1: lotag has linking semantics
2: hitag
4: extra, 8: xvel, 16: yvel, 32: zvel, 64: owner (custom only)
Custom setting about which sprites have what kind of linking can be programmed
via EVENT_LINKTAGS: it receives a sprite index as the 'current sprite' and is
supposed to return the bit field in RETURN.
An example which lists sprites and their linking hi- and lotags is provided in
the state 'listusedtags' in a.m32.

- 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 was more or less done by trial and error rather than understanding what
exactly is going on there. In any case, the code for all the different ending
scenes ought to be factored out instead of being duplicated with subtle
differences every time.

This is so that when hud_bgstretch is disabled (i.e. background pictures are
not stretched to the whole screen), the frame buffer has no leftover contents
from previous frames on the sides of the screen. This was particularly noticable
when using the console.
The "places" are the following:
- before drawing an anim frame
- before drawing a "full-screen" background
- while displaying logo, titlescreen, loadscreen
(this leaves a couple others which I didn't test, and didn't tweak)

Also, do a setpalettefade(..., end) when breaking fadepaltile now, too.

When requesting an increasing ramp, the upper limit is taken to be exclusive.
When it is passed to G_FadePalette, only the lowest 6 bits are passed further
to setpalettefade, which means that a limit of 64 is incorrectly set as 0.
Also, when breaking from the fade loop, set the fade value to the end one for
fadepal!

Allow all drivers for now; if anything, we should start maintaining a
blacklist now that most Intel chips have decent enough support to be
able to run stuff satisfactorily.

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.

The showview command transforms the 320-based screen bound coordinates to the real
screen bounds like xreal = (x*xdim)/320, which shows a bias towards zero: for
example, for a 1680 screen width, the maximum permissible value 319 is mapped to
round_to_zero((319*1680)/320) == 1674. (The rounding is implicit in the integer
division). This makes it impossible for a view to cover the whole screen with any
other resolution than 320x200. The new command transforms the bounds like
xreal = (x*(xdim-1))/319, which would map 319 to 1679 in the preceding example.

(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.
git-svn-id: https://svn.eduke32.com/eduke32@2569 1a8010ca-5511-0410-912e-c29ae57300e0
The syntax is as follows:
makepalookup { <token-list...> }
where valid tokens are
* pal <palnum>: the palette number, 1 .. 250
* red <num>, green, blue (or r, g, b): the fog color components on a 0 to 63 scale.
Components that are not present are assumed to be 0.
* remappal <palnum>: the palette number to take the index remapping from, i.e. 21
for blue -> red. When absent, defaults to 0.
* remapself: when present, specifies that the remappal is the same as the 'pal'.
This is to prevent textual redundancy when overwriting existing palookups.
Examples (best tested with tile #251):
1) makepalookup { pal 200 red 30 remappal 23 }
This creates palookup 200 with a fog of (30,0,0) and a blue-to-yellow remapping
(assuming it has not been changed before)
2) makepalookup { pal 21 red 30 remapself }
This 'fogifies' palookup 21 with a red fog.
3) makepalookup { pal 21 red 30 }
This overwrites palookup 21 with a red fog, but clears the blue-to-red remapping.
The fog aspect of this command affects the GL modes just like 'fogpal', but the
remapping has no effect for hightiles.
- Also, silently clamp 'fogpal' r,g,b values to the range 0 .. 63.

Instead of drawing the rooms and masks with the classic renderer once.
The captured scene is transformed to use the base palette, so that the
screenshot will also show up in classic. No aspect correction is done.

The primary change is that things have been made memory-clean. Some of these
pointers may point to wildly different places during the course of the program
such as statically or dynamically allocated storage, the buffer returned by
getenv() (which must not be modified according to the docs), or an element of
argv[]. Consequently, we need to strdup, or better, dup_filename them if they
are ever to be passed to a function that modifies their pointed-to data.
Specifically:
- added statics or consts according to usage
- 3 new functions clear{Grp,Def,Script}NamePtr, only 'Def' one extern for now
- in G_CheckCommandLine, don't strip 'const'; use Bstrncpyz where appropriate
- remove multiple declarations
Also, warn if an application parameter has been ignored (not matched).

This additionally fixes leaks that were caused by traversing the file name
list with the 'findfiles' pointer and not clearing them afterwards (even if
there was a handle to the list head via 'findfileshigh').

Don't actually replace the instances in the code now.
Additions in common.h:
- fnlist_t, which combines CACHE1D_FIND_REC *finddirs, *findfiles and
int32_t numdirs, numfiles
- the FNLIST_INITIALIZER macro, which MUST be used for automatic variables
- fnlist_clearnames, fnlist_getnames functions
- G_LoadGroupsInDir, G_DoAutoload, two often-occurring uses of these

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