Noticed while testing an earlier fix - after your pet consumes a large mimic
corpse don't have it remain leashed once it begins to mimic something

1ef3167ca0 Steed #monster breath feedback
Using #monster to make the steed use the breath weapon often
failed because the steed did not want to breathe at weak or
too strong monsters.
Make #monster force the steed use the breath, and if there is
no targets available, make the steed make some noise as feedback.

aedb24d343 partly fix issue #1336 - pets vs floating eyes
Issue reported by ars3niy:  pets with reflection or ranged attacks
would only attack floating eyes when rolling the 10% random chance
that other pets have even though they could have always safely
attacked.

This fixes the situation for melee attacks by pets who have
reflection.

dog_move() is too complicated for my feeble brain to cope with the
ranged attack aspect.  Pets still won't use ranged attacks against
floating eyes.

With the fix for reflection, I discovered that silver dragons
would be subjected to floating eyes' passive paralysis even when
their breath attack was suppressed.  (It wouldn't impact them, due
to reflection, but the message about the floating eye being hit by
its reflected gaze was being delivered without being preceded by
any message since no attack had taken place yet.)  This fixes that.

\#1336 is still open

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.

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.

6c0ae092c6 distinguish global variables that get written to savefile
The g? structs had a mix of variables that were written to
the savefile, and those that were not.

For better clarity and to distinguish those that end up in
the savefile, relocate some g? variables that get written
directly to the savefile into different structs.

This updates EDITLEVEL, although technically it probably
didn't need to, since savefile contents are not changing.

    gy.ymin             -> svy.ymin

Related note:
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
savefile directly, but the objects/monst/trap/lightsource/timer in the
chains they point to are. That can be changed, if desired.
Examples: gi.invent, gm.migrating_objs, gb.billobjs, gm.migrating_mons,
          gf.ftrap, gl.light_base, gt.timer_base

b662134eba Fix: bill_dummy_obj billed excessively for stacks
Add a way to request that unpaid_cost() produce the cost for a single
item, which is necessary for the price adjustment made in
bill_dummy_object.  Another option would be to simply divide by quan in
bill_dummy_object, but this might be more future-proof in case
unpaid_cost ever involves more than simple multiplication by quan
(e.g. the use of alternate units vs the base price, as are used for
globs).

fe8710532e Fix: latent bug with finish_meating on catchup
Some players of 3.6 recently noticed that sometimes, mimics in shops
seemed to have moved around even before the player had entered the shop
or done anything to uncloak them.  I found that this was because
finish_meating was being called for all non-eating monsters when
restoring a level (monsters that weren't eating anything would have
meating == 0 so always pass the 'imv > meating' check).  This would
uncloak mimics -- but not all the time, because the 'mappearance != 0'
test meant mimics disguised as strange objects weren't uncloaked.  I
think that was meant to be an additional check to confirm the monster
really did have a disguise, but in reality it meant that M_AP_OBJECT
"strange object", M_AP_MONSTER "giant ant", etc disguises wouldn't be
removed by finish_meating.

As it turns out, this was mostly fixed by coincidence in 221e4a7, which
fixed the "exclude actual mimics" check in finish_meating.  So at this
point in 3.7 it's largely a latent bug, but it still had the potential
to improperly uncloak non-mimics who can disguise themselves (like the
Wizard of Yendor, maybe?), and could cause other problems if
finish_meating were updated to have additional effects, or if some
monster types were made to disguise themselves as a strange object when
eating a mimic.

9052bd5099 fix #K3925 - u.ustuck of long worm tail
Don't allow stick/wrap/engulf attacks directed at long worm tails
to succeed.  Achieved by making sure that 'notonhead' is up do date
in a bunch of places and utilizing the fairly recent can't-{stick,wrap,
engulf}-unsolid-monsters code.

Should prevent a 'sanity_check' warning about being too far from
u.ustuck that would happen when holding the tail while the head was
not adjacent to the hero.

Also don't let pet ranged attacks from choosing a long worm's tail
as target.  They'll still be able to target long worms provided that
the head is lined up and not shielded by tail segment(s).

3890491ef0 Fix: message when pet moves from water to eat
The <x,y> params of dog_eat are the pet's starting position that turn,
not necessarily the position of the object being eaten.  If the pet is
doing a combined move-and-eat action, <x,y> will be its original spot,
but it will have already moved to <mtmp->mx,mtmp->my>, where the food
object also is.

The attempt to check whether the eating was happening out-of-sight
underwater (to suppress the message in that case) was checking the pet's
starting location, not its new location/the location of the food object.
So if a pet moved from water to land to eat something, the chowing-down
message would be improperly suppressed (and presumably the message for a
pet moving from land to water to eat would be improperly left
_un_suppressed, though I didn't actually try to reproduce that).

02a48aa8cf split g into multiple structures
The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.

It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.

Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.

To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.

A global variable named 'amulets', would be found in ga.
    ga.amulets
     ^ ^
A global varable named 'move', would be found in gm.
    gm.moves

2b04cc9f5b fix issue #843 - vampire revival sequencing
Reported by Umbire:
|You kill SpaceMannSpiff!  SpaceMannSpiff puts on a dwarvish cloak.
|SpaceMannSpiff puts on a dwarvish iron helm.
|The seemingly dead SpaceMannSpiff suddenly transforms and rises as
| a Vampire.

This was tough to reproduce but I finally managed it.  The issue
text mentions that it was fixed by copperwater in xNetHack with
commit 8c4af50f0aa3e72522f3eb98df039ff25c2a1ea0 to the repository
for that variant.  My attempt to cherry-pick that failed--I'm not
even sure whether it should have been expected to work--and some of
the code has been impinged upon by changes, so I ended up applying
the contents of that commit manually.

The commit changes how/when monsters put on new armor rather than
anything directly related to vampires.  Circumstances similar to
the example above now yield:
|You kill SpaceMannSpiff!
|The seemingly dead SpaceMannSpiff suddenly transforms and rises as
| a Vampire.
on one turn, then on the next turn the revived vampire produces:
|SpaceMannSpiff puts on a dwarvish cloak.

My test case only had one item of interest; I assume that the second
item of armor gets worn on a subsequent turn rather than at the same
time as the first one.

2108abd30d pets eating containers
Apply the patch from entrez that makes pet gelatinous cubes who eat
containers engulf rather than digest the contents, like non-tame
g.cubes.  Unlike the latter, tame ones will immediately drop the
stuff they just engulfed and might subsequently eat it all anyway.

59cf69085a Fix: non-swimming pets eating underwater food
Commit 32234b1d in 2003 mentioned in its commit message that pet dragons
shouldn't be able to eat underwater food items.  This was mostly true:
non-swimming pets wouldn't select underwater food as a goal, and
wouldn't spend an action eating something unreachable on their current
position.  But the "combined eat and move" case in dog_move didn't check
could_reach_item, so if a non-swimming pet happened to move to a spot
with underwater food for some reason, they could eat it on that turn
anyway.  This commit should close this loophole and prevent non-swimming
monsters from eating underwater food (or other unreachable food) even if
they happen to fly over its position.

30b557f7d5 change xchar to other typedefs
One of the drivers of this change was that screen coordinates require a
type that can hold values greater than 127. Parameters to the window
port routines require a large type in order to be able to have values
a fair bit larger than COLNO and ROWNO passed to them, particularly for
their use to the right of the map window.

This splits the uses of xchar into 3 different situations, and adjusts
their type and size:

                        xchar
                          |
               -----------------------
               |          |          |
            coordxy     xint16     xint8

coordxy: Actual x or y coordinates for various things (moved to 16-bits).

xint16:  Same data size as coordxy, but for non-coordinate use (16-bits).

xint8:   There are only a few use cases initially, where it was very
         plain to see that the variable could remain as 8-bits, rather
         than be bumped to 16-bits.  There are probably more such cases
         that could be changed after additional review.

Note: This first changed all xchar variables to coordxy. Some were
reviewed and got changed to xint16 or xint8 when it became apparent that
their usage was not for coordinates.
