542d1db5f4 Another fix for #K4317 - monster grudge
Undead monsters created by the level creation routine do not grudge
other (zombifiable) monsters created during the level creation.

This of course doesn't prevent the grudge happening with monsters
created during gameplay.

Invalidates saves and bones.

398681fd18 fix? #S15277 - Engulfer gets placed over itself
Bug report was that engulfer killed hero who was life-saved and expelled
onto a rolling boulder trap which resulted in the death of a bystanding
monster.  That triggered an impossible about placing the engulfer onto
the map at an already occupied spot (containing the engulfer itself)
while dealing with the dead bystander.

This removes the code in mon_leaving_level() that was putting the
engulfer on the map.  I'm no longer able to reproduce the problem it
was intended to solve, and if that problem (message delivery about the
swallow attack delivered with the engulfer missing from the map) exists,
it would be less severe than the impossible feedback.  I didn't attempt
to reproduce the actual reported problem since the code removal should
make it moot.

Once again, the bug report via the web contact form got misclassified
as spam.

a561538c2a cursed potions of invisibility for monsters
Extend the recently changed behavior for cursed potion of invisibility.

Monsters won't drink potions of invisibility if already invisible so
can't accidentally or voluntarily make themselves visible again, but
let player make them become visible by hitting them with thrown or
wielded cursed potion of invisibility.

They don't have any concept of temporary invisibility that might let
them remain invisible while losing permanent invisibility, so they
just lose the latter and immediately become visible.

5d7b7b823a Monster-slowing effects work better against faster enemies
Based on the principle that there should always be at least two
solutions to any given problem, this allows monster-slowing magic
to be an effective solution to fast low-monMR monsters (in
particular home-plane air elementals, who after recent commits
could reasonably be dealt with using good AC, but I want a second
good option to be available, in addition to the existing mediocre
options).  This helps to make playing with bad AC (for whatever
reason) more viable.

Adjust restrap() so that a revealed mimic won't disguise itself while
sleeping. This seems to be in keeping with mimic lore.

Also, normal shop sounds (chime of register etc.) will wake a
mimic up from indeterminate sleep.

695c6ef3ac fix issue #1434 - engulfed gas spore explosion
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

5fe746a0d6 fix issue #1435 - vampire leaders as wolves
Issue reported by by vultur-cadens:  a vampire lord or lady might change
to wolf form while flying over water or lava, ending flight and dropping
into that water or lava.  It would then drown or burn up, revert to
vampire leader form and resume flying, then be teleported since it was
past the check for being in flight.

The fix is pretty staightforward.  It is still possible to force wolf
form with the monpolycontrol option, leaving the wolf standing on water
(didn't test for lava) and then drowning on its next move, where it will
revert to vampire form but no longer teleport away.  There's no need for
a wizard mode hack to behave more stringently.

228870706b Balance fixes to monster/monster zombie creation attacks
These were unbalancing the game a) in the Castle and b) if they
woke up unique monsters (most notably the Wizard of Yendor).

I considered adding a difficulty check, but this commit instead
just directly fixes the symptoms. (It doesn't make sense for the
Castle to contain a monster that would kill or be killed by its
inhabitants: they should have died long before the hero arrived.
So for liches/zombies to exist in the Castle at all, there must be
a truce.)

c24786430f 'struct former' -> 'struct ebones'
Some variants were already using a similar approach
using a struct called 'ebones', so adopt the same naming
so NetHack-3.7, hardfought, and some variants are using
the same name.

As before there are fields in the struct that are not
currently used by NetHack-3.7, but the intent is that
hardfought save and bones files can be loaded by
NetHack-3.7 without code modification, for debugging
bug reports.

This invalidates existing save and bones files.

d785f7a649 add two unused fields for hardfought save compatability
There are two hardfought code additions that render save and bones files incompatible
with the upstream NetHack-3.7, and that makes testing with hardfought
save and bones files more challenging than it needs to be, when
investigating and troubleshooting bug reports.

Add some unused fields to advance towards achieving save file parity with
hardfought, which is a significant source of play-testing for NetHack-3.7.

1) the elbereth field addition to u_conduct

This adds an unused placeholder field named 'hf_reserved1', at the appropriate
place in u_conduct to achieve struct field parity with the one in use on
hardfought.

2) hardfought adds a field to struct monst:
    char former_rank[25]; /* for bones' ghost rank in their former life */

Instead of adding that to every monst, this adds a new mextra struct
named 'former', which currently contains the equivalent 25-character
field called 'rank' which can hold the content that was in the
former_rank[25] field. That way, the field will only be added when it
is needed.

A pull request https://github.com/k21971/NetHack37/pull/2 has been
done on hardfought to do it the same way (untested there as of yet).

Even though NetHack-3.7 does not utilize that information presently,
this will be a further step toward allowing hardfought-generated save
and bones files to be used for troubleshooting, without modification,
on a similar architecture running stock NetHack-3.7 code.

That savefile parity won't be achieved until the after the
hardfought pull-request mentioned above (or equivalent) is merged.

As this change will not be compatible with existing save and bones
files, it will be accompanied with an EDITLEVEL increment.

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.

cbc93a0555 github issue #1312 - prot from shape changers
Issue reported by youkan700:  shape change anomalies.  Shapechangers
could change shape despite active protection-from-shape-changers if
hero wore two rings of protection from shape changers and took one
off.  Shapechangers who migrated to a not-yet-visited level that
eventually got visited with protection from shape changers in effect
would be stuck in their current shape, even if the PfSC attribute
got toggled off and back on.

The issue included suggested fixes and those are what I've used.  I
noticed a third case that only applies to wizard mode:  if player
used #wizintrinsic to set a timed value for PfSC, monsters wouldn't
resume changing shape after it timed out, unless/until it got toggled
on and back off via a PfSC ring or hero left the level and returned.

1fe23ff4d9 vampshifters vs closed doors
If a vampire in fog cloud form moves under a closed door and then
before moving further gets killed and revives in vampire form,
destroy the door instead of moving the vampire to a nearby open
spot (which might be a distant spot if the map is crowded).  If the
door is trapped, explode the trap.  That will damage the vampire but
usually not by enough to kill it.

This probably ought to be generalized to be done for any shape change
at a closed location but I ran out of gas.

dcf18b2b69 fix #K4292 - tame hider-under vs cursed object
A pet with the hides-under attribute could hide under cursed objects
if it first moved reluctantly to their location.  Also, the messages
seem contradictory:
| The cobra slithers reluctantly over a scroll labeled DUAM XNAHT.
| You see your cobra slither under a scroll labeled DUAM XNAHT.
First over, then under, but that was actually accurate; the monster
moved, then after it was on the pile it hid underneath.

Change hideunder() to not let pets hide under an object if it is
cursed or any object in its pile is cursed.  Initially I was just
going to check the top item and the item directly beneath it, but
reluctance to move there extends to the whole pile so I made hiding
do so too.

Change the first message to move reluctantly "onto" an object since
"over" suggests that it has continued past the item, unless it is
actually flying or levitating so truly "over" the pile.

for mongone() as well as for mondead().
