0bd5b3d39e teleport feedback for STRAT_APPEARMSG mon
Reported by entrez:  if a monster with the STRAT_APPEARMSG flag is
seen to teleport away from its current position, an arrival message
would always be given too.  If you couldn't see that arrival, you'd
get nonsensical "It suddenly appears!".

Minor fix:  when a monster is seen to vanish at one spot and appear
at another, if it was not close you'd get either "appears closer to
you" or "appears farther from you" even if the new spot was the same
distance as the old spot.

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.

This increments EDITLEVEL in patchlevel.h

bb238b5ef3 avoid becoming stunned due to level teleporting
Reported by entrez:  the code to have a hero become stunned for 1..3
turns when going though a level teleporter trap effectively negated
teleport control (except in wizard mode which is probably why this
slipped through).  Make the effect happen after level_tele instead of
before, change it from being stunned to being confused, and only
happen if hero lacks teleport control.

The association between confusion and level teleportation already
exists and this might be just enough of a hint for someone who isn't
aware of that yet to figure it out.  (Probably just wishing thinking.)

Magic portal traversal hasn't changed; it still causes brief stun.

Switch to using a macro invocation Verbos(n, s) in place of the

Provide the mechanics for individual suppression of any of the
existing messages that were considered verbose.

Mechanics only - this code update does not provide any means of
setting the suppression bits.

iflags.verbose = 0
is still a master suppression of all the verbose messages.

iflags.verbose = 1
turns on the verbose messages only for those whose suppression
bit is 0 (not set).

Add some basic functions to iterate through the monster list,

f0c7394968 git issue #717 - avoid putting monsters on scare \
monster and Elbereth unless there's no other choice.

Suggested by NetSysFire, don't create new monsters on top of scrolls
of scare monster.  Not mentioned in the suggestion:  unless they are
a type of monster that isn't affected by such scrolls.  This extends
it to teleport destination too.

Avoid placing a monster on a scroll of scare monster or on engraved
Elbereth if there are other locations available.  Only performed for
callers of goodpos() who explicitly request it, which at the moment
are makemon(), rloc(), and enexto().

Also, propagate 'mmflags_nht' to a bunch of places that were left
using long or unsigned for makemon() and goodpos() flags.  I didn't
attempt to be systematic about that though.

e3490743e0 divine gift of spell knowledge
Remove the conduct-specific aspect of receiving spells as prayer boon.
Anyone now has a 25% chance of having the spell directly implanted
into their head, not just characters who have maintained illiterate
conduct.  It can now also restore a forgotten spell or refresh one
that is nearly forgotten.  It still tries to choose a spell which
isn't already known (new: or was known but has been forgotten) but if
it picks one that is known and doesn't need refreshing, a redundant
book will be given, same as the behavior in earlier versions.

The chance for receiving a blank spellbook is higher when that item
is undiscovered.  When given as a prayer reward, make it become
discovered even if hero doesn't read it so that it will be less likely
to be given again.  There's a 1% chance for that auto-discovery to
happen with other bestowed books.  Unlike blank boots, having the book
be discovered doesn't lessen their chance of being repeat gifts.

Minor bug fix:  for a spell implanted from scratch, the book remains
unknown.  That's ok; it's actually more interesting than discovering
a book you haven't seen yet.  But after acquiring and reading the book
you could get "you know <spell> quite well already" and the book would
stay undiscovered even though you were just told what spell it's for.

1e951db9bc Fix: monster hurtling and liquid
A monster hurtling over liquid would drown immediately the instant it
touched the first square of water, even if normally it would have kept
moving (e.g. hurtling over a short moat).  Additionally, its placement
on liquid would not take into consideration other monsters, so it could
overwrite an existing monster on that spot and lead to an impossible,
and/or two monsters occupying a single position.

Fix these issues, so that liquid effects like drowning only happen if
the monster ends up in liquid at the end of the hurtle, and so that
other monsters in the way will stop it early even if they're floating
over or swimming on a pool/water/lava square.

Also use canspotmon instead of canseemon for the wiztelekinesis debug
command.

1ada454fbe wizard mode ^T
Noticed while testing the stair labeling, knowing the teleport away
spell (and without innate teleport ability--not sure whether that's
a factor), using ^T always attempted to cast the spell, even if you
used m^T to explicitly request wizard mode telport on demand.  Since
my samurai had no chance to cast such a high level spell, I couldn't
use ^T any more.

With a different character, I ended up with 15(2) energy after a ^T
attempt failed.  I've put in a fix for this but after the other one
I don't think it matters.

8bd08ebb71 level teleporters vs Ft.Ludios
From newsgroup discussion where slash'em changes have revealed a
latent nethack bug:  prevent placing level teleporters in single-
level branches.  The Knox level doesn't have any level teleporters
(or random traps) but wizard mode wishing could create them there.
They wouldn't do anything because the only possible destination
would be the same level.  Pushing a boulder onto one used to trigger
an infinite loop (and still does in slash'em, which has other
single-level branches besides Ft.Ludios) trying to relocate it.

Boulder pushing was changed 15 years ago to prevent the infinite
loop and to avoid giving "the boulder disappears" message when a
level teleporter failed, but rolling boulder traversal lacked that
same change--it wasn't vulnerable to looping but could give an
inaccurate message claiming that the boulder disappeared when it
actually didn't.  Fixing this is a bit late; rolling boulder trap
creation was recently changed to not choose a path that rolls over
teleportation or level tele traps any more.

c9673b3d9e more window port interface adjustments
further adjustments to the window port interface to pass a pointer
to a glyph_info struct which describes not just the glyph number
itself, but also the ttychar, the color, the glyphflags, and the
symset index.

This affects two existing window port calls that get passed glyphs
and does the parameter consistently for both of them using the
glyph_info struct pointer:
	print_glyph()
	add_menu().

The recently added glyphmod parameter is now unnecessary and has been
removed.

0c3b9642e4 pmnames mons gender naming plus a window port interface change
add MALE, FEMALE, and gender-neutral names for individual monster species
to the mons array. The gender-neutral name (NEUTRAL) is mandatory, the
MALE and FEMALE versions are not.

replace code uses of the mname field of permonst with one of the three
potentially-available gender-specific names.

consolidate some separate mons entries that differed only by species into a
single mons entry (caveman, cavewoman and priest,priestess etc.)

consolidate several "* lord" and "* queen/* king" monst entries into
their single species, and allow both genders on some where it makes some
sense (there is probably more work and cleanup to come out of this at some
point, and the chosen gender-neutral name variations are not cast in stone
if someone has better suggestions).

related function or macro additions:
    pmname(pm, gender) to get the gender variation of the permonst name. It
    guards against monsters that haven't got anything except NEUTRAL naming
    and falls back to the NEUTRAL version if FEMALE and MALE versions are
    missing.

    Ugender to obtain the current hero gender.
    Mgender(mtmp) to obtain the gender of a monster

While the code can safely refer directly to pmnames[NEUTRAL] safely in the
code because it always exists, the other two (pmnames[MALE] and
pmnames[FEMALE] may not exist so use:
    pmname(ptr, gidx)
      where -ptr is a permonst *
            -gidx is an index into the pmnames array field of the
             permonst struct
pmname() checks for a valid index and checks for null-pointers for
pmnames[MALE] and pmnames[FEMALE], and will fall back to pmnames[NEUTRAL] if
the pointer requested if the requested variation is unavailable, or if the
gidx is out-of-range.

Allow code to specify makemon flags to request female or male (via MM_MALE
and MM_FEMALE flags respectively)to makedefs, since the species alone doesn't
distinguish male/female anymore. Specifying MM_MALE or MM_FEMALE won't
override the pm M2_MALE and M2_FEMALE flags on a mons[] entry.

male and female tiles have been added to win/share/monsters.txt.
The majority are duplicated placeholders except for those that were
separate mons entries before. Perhaps someone will contribute artwork in the
future to make the male and female variations visually distinguishable.

tilemapping via has the MALE tile indexes in the glyph2tile[]
array produced at build time. If a window port has information that the
FEMALE tile is required, it just has to increment the index returned
from the glyph2tile[] array by 1.

statues already preserved gender of the monster through STATUE_FEMALE
and STATUE_MALE, so ensure that pmnames takes that into consideration.

I expect some refinement will be required after broad play-testing puts it to
the test.

    consolidate caveman,cavewoman and priest,priestess monst.c entries etc

This commit will require a bump of editlevel in patchlevel.h because it alters
the index numbers of the monsters due to the consolidation of some. Those
index numbers are saved in some other structures, even though the mons[] array
itself is not part of the savefile.

Window Port Interface Change

Also add a parameter to print_glyph to convey additional information beyond
the glyph to the window ports. Every single window port was calling back to
mapglyph for the information anyway, so just included it in the interface and
produce the information right in the display core.

The mapglyph() function uses will be eliminated, although there are still some
in the code yet to be dealt with.

win32, tty, x11, Qt, msdos window ports have all had adjustments done to
utilize the new parameter instead of calling mapglyph, but some of those
window ports have not been thoroughly tested since the changes.

Interface change additional info:

    print_glyph(window, x, y, glyph, bkglyph, *glyphmod)
            -- Print the glyph at (x,y) on the given window.  Glyphs are
               integers at the interface, mapped to whatever the window-
               port wants (symbol, font, color, attributes, ...there's
               a 1-1 map between glyphs and distinct things on the map).
            -- bkglyph is a background glyph for potential use by some
               graphical or tiled environments to allow the depiction
               to fall against a background consistent with the grid
               around x,y. If bkglyph is NO_GLYPH, then the parameter
               should be ignored (do nothing with it).
                -- glyphmod provides extended information about the glyph
               that window ports can use to enhance the display in
               various ways.
                    unsigned int glyphmod[NUM_GLYPHMOD]
               where:
                    glyphmod[GM_TTYCHAR]  is the text characters associated
                                          with the original NetHack display.

                    glyphmod[GM_FLAGS]    are the special flags that denote
                                          additional information that window
                                          ports can use.

                    glyphmod[GM_COLOR] is the text character
                                       color associated with the original
                                       NetHack display.

Support for including the glyphmod info in the display glyph buffer
alongside the glyph itself was added and is the default operation.
That can be turned off by defining UNBUFFERED_GLYPHMOD at compile time.
With UNBUFFERED_GLYPHMOD operation, a call will be placed to map_glyphmod()
immediately prior to every print_glyph() call.

81ec2bfa2a pull request #386 - discovering teleport scroll
Since teleporation gives a "you matrialize" message even when
arriving close by, the old behavior of not learning a scroll of

no longer made sense.  Always [almost] discover teleport scroll

Also adds one-shot teleport control when reading a blessed scroll
of teleportation.  I changed that to be prevented when hero is
stunned, same as with full-fledged teleport control.
