remove mhitm.c's 'otmp'
Get rid of a couple of variables that were file scope and then
incorporated into 'g'. This should prevent the situation where
attacking a shade gave bogus feedback about glorkum although I
never did reproduce that.
This eliminates g.otmp and g.dieroll but leaves a couple of others.

mon's glorkum pass harmlessly through the shade
I couldn't reproduce the problem; it appears to depend upon whether
the file-scope variable 'otmp' has a stale value, and that might
happen after a monster has tried to steal mon's saddle. However,
the code pointed out in the report is clearly wrong. This prevents
feedback of "glorkum" (with plural verb since quantity of 0 isn't 1),
but the potential stale value hasn't been dealt with.

fix #H4545 - stack of scrolls of scare monster
Reported 3.5 years ago. Specifying a count for pickup to pick up a
subset of a stack was processed after scrolls of scare monster were
handled, so a whole stack of those got picked up or crumbled to dust
whether you gave a count or not. Also, if you were too encumbered to
pick up the full stack, they still all crumbled or all changed state
to crumble next time, then for the latter case you picked up as big a

fix github issue #302 - divide by 0 crash

would happen if 'bogusmon.txt' is empty. makedefs probably ought to

There is now one hardcoded bogus monster to fall back to: 'bogon'.

panictrace_libc
Try to make the tracebacks generated via PANICTRACE's libc method
be more readable. There tends to be a lot of blank space in the
middle of lines, depending on the length of the program's or
libraries' file names, which can make lines wrap and the whole
thing sometimes be harder to make out. Narrow it by squeezing out
some spaces from each line before writing to reduce the chance of
line wrapping. That isn't guaranteed to make things ledgible but
seems to help quite a bit. Also, force the line number inserted
by nethack to be two digits so when spanning from line 9 to line 10
it doesn't cause the field positions to shift by a column. (Using
'#panic' doesn't have enough stack frames to illustrate that.)
I think the original libc formatting was designed for the address
column to hold a 32-bit value ('0x' prefix and 8 hex digits), and
eventually extending that to handle 64 bits ('0x' prefix and 16 hex
digits) made things wider than intended. But the gradual increase
in the length of function names we use is also a factor.

fix github issue #309 - random role segfault
Role selection is insanely complex. I had to use a debugger to force

The analysis was correct: it could use rn2(14) to pick a role (valid

The terminating element of roles[] passes all the ok_role(), ok_race(),
etc tests. Explicitly exclude that element when collecting the roles

throw-and-return vs !fixinv
Implement the request that a wielded+thrown aklys be given the same
inventory letter when it returns and is caught and rewielded, even for
the !fixinv setting where inventory letters don't stick. Works for
Valkyrie-thrown Mjollnir and returning (ie, didn't hit) boomerangs as
well as for aklys.
I'm not sure how useful this really is, because on the rare occasions
that it either doesn't return or fails to be caught, it won't be given
the same letter when subsequently picked up. So the player who relies
on it will still be vulnerable to using the wrong letter next time a
throw is attempted. But at least picking it up explicitly displays
the new inventory letter, unlike catching it upon return.

February 2020 options.c overhaul
combine boolean and compound options into a single allopt[] array for
processing in options.c.
move the definitions of the options into new include/optlist.h file which
uses a set of macros to define them appropriately.
during compile of options.c each option described in include/optlist.h:
1. automatically results in a function prototype for an optfn called
optfn_xxxx (xxxx is the option name).
2. automatically results in an opt_xxxx enum value for referencing
its index throughout options.c (xxxx is the option name).
3. is used to initialize an element of the allopt[] array at index
opt_xxxx (xxxx is the option name) based on the settings in the
NHOPTB, NHOPTC, NHOPTP macros. Those macros only live during the
compilation of include/optlist.h.
each optfn_xxxx() function can be called with a req id of: do_init, do_set,
get_val or do_handler.
req do_init is called from options_init, and if initialization or memory
allocation or other initialization for that particular option is needed,
it can be done in response to the init req.
req do_set is called from parseoptions() for each option it encounters
and the optfn_xxxx() function is expected to react and set the option
based on the string values that parseoptions() passes to it.
req get_val expects each optfn_xxxx() function to write the current
option value into the buffer it is passed.
req do_handler is called during doset() operations in response to player
selections most likely from the 'O' option-setting menu, but only if the
option is identified as having do_handler support in the allopts[]
'has_handler' boolean flag. Not every optfn_xxxx() does.
function special_handling() is eliminated. It's code has been redistributed
to individual handler functions for the option or purpose that they serve.
