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!

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.

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.

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
git-svn-id: https://svn.eduke32.com/eduke32@2549 1a8010ca-5511-0410-912e-c29ae57300e0
As inauguration, move G_AddGroup, G_AddPath and struct strllist there.
The header is located in build/include, because in the future, code that resides
closer to (but is not strictly part of) the engine might need to be factored
into here. The source file, however, is in the source/ directory.

- 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

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.

The code in the editor was potentially doing a strcat on a strdup'd string.
Also, rename AddGamePath to G_AddPath in astub.c and add CODEDUP markers
because shared stuff like this ought to be factored out into a separate
source file some time.

Skill names are defined via 'defineskillname' as before, but the index
of the last non-empty skill name (plus one) is taken as the skill count.
So, if you only define the 6th, there will be no effect.
Note that currently, there is no way to specify less than four skills
because the CON parser doesn't allow the empty string for the name (it'll
go beyond the line) and because the default skill names are initialized in
EDuke32 too, in addition to the CONs.

- Add proper $(*LDFLAGS) to which LTO and ARCH are correctly passed.

It has always annoyed me how floors with "shirt-color" type palookups like 21
affected the color of its containing sprites and HUD-drawn stuff. This commit

- 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).
