84ddf85cb4 new composite status conditions: weaponstatus,\
armorstatus, and terrainstatus

This adds three special status items to show at a glance what the hero
is wielding, wearing, and standing on.

Each of the three items has its own boolean option rather than try to
fix them in with the existing opttional status conditions.  After a
lot of testing, I think the weapon and armor ones will prove useful
but the terrain one probably won't be.

Presently it is implemented for tty and curses.  When I developed it
six years ago, it was also working for X11 but I'm not able to test
the resurrection of that part so have left it out.

fcd9f5468c some coordxy follow-up
Return a couple of variables that actually held a direction back
to int from coordxy.

bhit() takes int params instead of coordxy.

boomhit() takes int params instead of coordxy.

xytod() renamed to xytodir(), and takes int params (promotion will handle
coordxy params).

dtoxy(coord *, int) renamed to dirtocoord(coord *, int).

5b22feb795 Reduce the effect of luck on to-hit
Luck has a massive effect on the to-hit chance; maximum luck alone
(which almost everyone has past the midpoint of the game) gives
10 points to to-hit, so accounts for 50% chance alone, excluding all
other effects.

Multiple variants do something similar to this, so it is well tested.
This version comes from xNetHack by copperwater <aosdict@gmail.com>,
and allows the +1 or -1 luck adjustments of early game, such as full moon,
to have an effect.

8c29b20010 Accurately track which items have been discovered, even if not #named
This fixes a couple of bugs: a long-standing bug in which writing a
scroll by label could fail even if you've already seen a scroll with
that label (due to the game not tracking whether or not you've seen a
scroll if it doesn't have a name); and a somewhat newer bug in which
spellbooks auto-identified by Wizard knowledge were marked as having
been encountered (rather than as known but not encountered).

Breaks save file compatibility, but not bones files.

177a5bcaf7 Wielded vegetables do no damage
It makes sense that a vegetable would do less damage than a hard
object would, as they're generally fairly soft, so it seems like a
likely thing for players to try if they're *intentionally* trying
to hit for zero damage (which could be useful in certain niche
cases, e.g. to wake up a sleeping monster without damaging it).

edd11009e9 issue #1447 - physical damage when polymorphed
Isssue reported by Tomsod:  hero-as-target section of mhitm_ad_phys()
was not handling hero's Half_physical_damage attribute.

The issue was about cloning a pet from hero who is poly'd into a
pudding but it was more general than that.  Half_physical_damage was
ignored for any hit by a monster-wielded weapon against poly'd hero.

It took a while to convince myself that Half_physical_damage wasn't
aleady being applied elsewhere but it doesn't seem to be.

Issue reported by Umbire:  a gas spore that got swallowed and killed
didn't die but exploded anyway, with the explosion affecting the map
instead of being contained in the swallower.

There was code to handle that but it wasn't being executed.  This fix
feels unclean but seems to work.

Stop attacking if target isn't there anymore.  Already handled for
two-weapon in normal form, not for multi-attacks in poly'd form and
for multi-attack monster vs hero or monster vs other monster.

I didn't attempt to reproduce the reported problem.  This fix is

Also prevent monsters that have hug or engulf attacks from knocking
target back with other attacks since that prohibits the grab/engulf

6c9d4df4a6 Fix: gremlin cry of pain could be heard while deaf
Main problem was there was no condition applied to this message, so
anyone would hear it even if they were deaf. Even assuming a cry of pain
is something that could be seen, the message was still printed when the
hero couldn't see the gremlin.

This puts both a deafness check and a range check on that cry (if a
gremlin somehow takes light damage on the other side of the map behind
many walls, it doesn't make much sense to hear its cry), and provides an
alternate message if the hero can't hear it, but can see it. The
alternate message does rely on the hero being able to /see/, not just
spot, the gremlin and the light it's shying away from -- if you can only
sense it, there is no special message.

cba032d187 another mimic fix
The report (sent directly to devteam) stated that the bump-into-mimic
code might crash when bumping into a mimic that is masqueraing as
some other monster.  Mimics don't actually do that, but the Wizard
of Yendor mimics another monster via Double Trouble.  All I got from
it though is
 |Wait!  That's <other monster>!
which won't crash but is a fairly useless message.

This changes it to be
 |Wait!  That <other monster> is <the Wizard of Yendor>!
which seems a bit bland but provides useful information.

539f039a83 maybe fix #K4316 - segfault stumbling onto mimic
I couldn't reproduce the reported problem but the backtrace suggests
that defsyms[monst->mappearance] was probably out of bounds so that
nh_snprintf() got bad data.  That might conceivably happen if the
glyph didn't match the mimic's mappearance, but I not sure how that
would occur.

This avoids using mappearance as an index into defsyms[] and should
give an impossible if that situation does come up.

e8ad3b4c19 Fix: quantum mechanics' tele attack had inverted negation check
Noticed when I summoned a quantum mechanic in wizard mode with a
starting character who should have no armor protection against their
teleport attack, but every touch resulted in "You are not affected". It
turns out the if statement checking for armor protection is backwards,
so you were never affected when you have no protection and were almost
always affected when you had good protection.

This appears to date back to when the all-purpose 'negated' variable was
removed and "You are not affected" moved to after the negation check;
the new conditional kept the ! by mistake.

0792e5fe9e expand implicit fallthrough detection to non-gcc compilers
gcc has recognized various "magic comments" for white-listing
occurrences of implicit fallthrough in switch statements for
a long time:

    The range and shape of "falls through" comments accepted are
    contingent upon the level of the warning. (The default level is =3.)

    -Wimplicit-fallthrough=0 disables the warning altogether.
    -Wimplicit-fallthrough=1 treats any kind of comment as a "falls through" comment.
    -Wimplicit-fallthrough=2 essentially accepts any comment that contains something
     that matches (case insensitively) "falls?[ \t-]*thr(ough|u)" regular expression.
    -Wimplicit-fallthrough=3 case sensitively matches a wide range of regular
     expressions, listed in the GCC manual. E.g., all of these are accepted:
        /* Falls through. */
        /* fall-thru */
        /* Else falls through. */
        /* FALLTHRU */
        /* ... falls through ... */
       etc.
    -Wimplicit-fallthrough=4 also, case sensitively matches a range of regular
     expressions but is much more strict than level =3.
    -Wimplicit-fallthrough=5 doesn't recognize any comments.

Plenty of other compilers did not recognize the gcc comment convention,
and up until now the compiler warning for detecting unintended
fallthrough had to be suppressed on other compilers. That's because the code
in NetHack has been relying on the gcc approach, and only the gcc approach.

The C23 standard introduces an attribute [[fallthrough]] for the
functionality, when implicit fallthrough warnings have been enabled.

Several popular compilers already support that, or a very similar attribute
style approach, today, even ahead of their C23 support:

       C compiler                       whitelist approach
       ---------------------------   -------------------------------------
       C23 conforming compilers         [[fallthrough]]

       clang versions supporting
       standards prior to
       C23                              __attribute__((__fallthrough__))

       Microsoft Visual Studio
       since VS 2022 17.4.
       The warning C5262 controls
       whether the implict
       fallthrough is detected and
       warned about with
       /std:clatest.                    [[fallthrough]]

This adds support to NetHack for the attribute approach by inserting a
macro FALLTHROUGH to the existing cases that require white-listing, so
other compilers can analyze things too.

The definition of the FALLTHROUGH macro is controlled in include/tradstdc.h.

The gcc comment approach has also been left in place at this time.

149cb96020 github issue #1299 - sleeping mimics
Issue reported by elunna:  sleeping mimics can grab the hero, and
zapping a concealed mimic with a wand of sleep describes the target
as a mimic but doesn't bring it out of concealment.

The grab-when-asleep case is reasonable.  It's a reflexive counter-
attack by a magical creature.  And the mimic wakes up in the process.
But the mimic wasn't being brought out of concealment.  Do that.

Unconceal mimics hit by wand of sleep unless already sleeping.

For better clarity and to distinguish those that end up in

There are some pointer variables that are heads of chains that were not
moved from 'g?' to 'sv?', because they are not actually written to the
