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.
Report states that the dungeon overview menu doesn't honor the
'menu_headings' option. However, dungeon overview is not a menu.
Despite that, switch its hardcoded use of bold and inverse to use
the option value instead. It doesn't really need two different
highlights and this allows user to control which video attribute
gets used. If someone wants different highlighting for overview
than for menus, they're out of luck.
Fixes#481
Implement a better fix for commit 2f4f7d22d ("Fix align type
mixup wth align mask") which was reverted in commit 4e35e8b5a
("Revert "Fix align type mixup wth align mask"").
In the present code, the field align in both struct altar and
struct monster is not an aligntyp, but an align mask with extra flags.
Change the type to match its actual use and improve the naming.
Consolidate duplicated code into a single routine.
Change the return type of induced_align() to be unsigned to match
amask usage.
Change the special level align mask values to be separate from
the normal align mask values.

Fix two cases of missed conversion of an alignment to an align mask.
Change induced_align()'s return type to unsigned int since it returns
an align mask (unsigned), not an align type (signed).
Gcc 9 has become more vocal with sprintf buffer overflow
checking. Remove these sprintf warnings by changing the
offending calls to a snprintf wrapper that will explicitly
check the result.
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.
Using 'ladder' as a variable conflicts with 'struct flag flags'
because of a macro in rm.h. Also remove or hide a couple of
unused variables.
The hack.c diff is unrelated; just a reformatting bit that I had
laying around.
Use a linked list to store stair and ladder information, instead
of having fixed up/down stairs/ladders and a single "special" (branch)
stair.
Breaks saves and bones.
Adds information to migrating objects and monsters for the dungeon
and level where they are migrating from.
The overview code could reveal the true alignment of an altar
if hero saw a mimic pretending to be an altar on that spot, or
reveal junk for the alignment when mimicking at altar on some
other spot.
Avoid passing macros that might evaluate their arguments more
than once to other macros which might also do that. The hidden
code expansion can easily get out of hand (although in this case
it was modest).
Also, get rid of the unused MSA_foo alignment values since two
of them had the values swapped. Lastly, make Amask2align() more
robust in case a value with the shrine bit set gets passed to it.
and out of save files so restore doesn't need to clear stale data.
Behavior should be the same as before, except that when entering
the endgame branch and discarding the main dungeon and its other
branches, lua theme context is now discarded for those too.
Allows creating shaped or themed rooms for the Dungeons of Doom
via lua script.
Invalidates bones and saves.
Makefiles updated for unix/linux by adding themerms.lua, but other
OSes need to have that added.
Instead of forgetting maps and objects, make amnesia forget skills.
Forgetting maps and objects could be circumvented with taking notes,
or by using an external tool to remember the forgotten levels.
Forgetting skills allows the player to optionally go down another
skill path, if they trained the wrong weapon in the early game.
Amnesia still forgets spells.
As a replacement for the deja vu messages when entering a forgotten
level, those messages will now indicate a ghost with your own name
existing on the level, given only when the level is entered for
the first time.
These changes based on fiqhack, with some adjustments.
Provide a way to communicate additional behaviors and/or appearances
desired from NetHack window port menus.
This is foundation work for changes to follow at a future date.
Some cleanup when chasing a memory leak. get_table_str() and
get_table_str_opt() return a value from dupstr() and it wasn't always
being freed. I'm not sure that I found the problem--maybe it involved
pointers turned over to Lua garbage collection--but did find a couple
of suspicious things in dungeon setup.
groundwork only - window port interface change
This changes the last parameter for add_menu() from a boolean
to an unsigned int, to allow additional itemflags in future
beyond just the "preselected" that the original boolean offered.
There shouldn't be any functionality changes with this groundwork-only
change, and if there are it is unintentional and should be reported.
