a3e12550ea savefile changes - part 1
This is the first of several savefile-related changes to
follow later. This one is groundwork for those later changes.

Remove internal compression schemes (RLECOMP and ZEROCOMP)
and discard the savefile_info struct that was primarily used to
convey which internal compression schemes had been in use.

Relocate some struct definitions into appropriate header files
for use by code to come in later changes.

Remove the two struct size-related fields from version_info and
from the nmakedefs_s. Instead, include a series of bytes near the
beginning of the savefile, representing the size of each
struct or base data type that impacts the historical savefile
content. Those are referred to as the "critical bytes".
(Related note: the "you" struct required two bytes, low and high,
due to its size).

Compare those critical bytes in a savefile against the NetHack
build that is reading the savefile. This allows mismatch detection
early in the savefile-reading process, and a clean exit, rather than
proceeding to read nonsensical values from the file. Include some
feedback on what the first mismatch was when encountering
one.

For arrays stored in the savefile, use loop-logic in the core
to write/read the array elements one at a time, rather than in
a single blob. This will be required for changes to follow later.
(impacts artiexist[], artidisco[], svd.dungeons[], svl.level_info[],
svl.level.locations[][], msrooms[] field of mapseen, svb.bases[],
svb.disco[] objects[], svm.mvitals[], svs.spl_book[], svd.doors[],
go.oracle_loc[], utrack[], wgrowtime[])

This also adds data model to the long version information.

This invalidates existing save and bones files due to the changes in
the information at the start of the file.

3cb7819c81 Split monster goal coordinate out of mstrategy field
Instead of packing a coordinate into unsigned long, store the goal in

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.

11a4fe42de 'selectsaved' again - update EDITLEVEL again
The role, race, gender, and alignment string values are 3 letters
preceded by a dash.  I was looking at "name-race-role-gend-algn"
and mistakenly treated them as 4 letters preceded by a dash.

Fixing that changes PL_NSIZ_PLUS and there is one item of that size
written into save files, so the fix invalidates existing save files.

1f36b98b8f 'selectsaved' extension
Instead of a menu listing

 q - Quit
show
 a - hero1-role1-race1-gend1-algn1
 b - hero2-role2-race2-gend2-algn2

 a - - hero1-role1-race1-gend1-algn1
 b - X hero2-role2-race2-gend2-algn2
 c - D wizard-role3-race3-gend3-algn3
 n - New game
 q - Quit
when any game in the list wasn't saved during normal play.  (Those
are sorted by character name; the playmode is just coincidence.)

The dash for 'normal' doesn't look great but -/X/D are codes used in
entries written to paniclog.  The whole playmode prefix doesn't look
particularly good but I suspect that most players relying on restore
via menu won't see it.

It should work when the character name has dashes in it but that
hasn't been properly tested.

The gender and alignment suffices reflect their value at the time of
save rather than at the start of the game.  That might be considered
a bug but it was easiest.

Increments EDITLEVEL; existing save and bones files are invalidated.

cf6509dde9 some reformatting (5 of 4)
Take care of most of include/*.h.  I punted on extern.h.

For both src/*.c and include/*.h, I used mismatched checks of
width > 79 to decide which files to look at and then width > 78
to decide which lines to maybe revise, so I didn't look at a bunch
of the files.

I don't plan to go back and do it right.  Shortening lines that are
80 or wider to less than 80 is the significant part.  Otherwise
emacs puts a backslash in column 80 and the rest of the line of text
on the next line of the screen, making things harder to read.

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.

    gb.bbubbles         -> svb.bbubbles

    gy.ymax             -> svy.ymax
    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

0e4083153c another EDITLEVEL increment
Since save and bones files just got clobbered, make another clobbering
change.  The 'queuedpay' field added to shop's ESHK(shkp)->bill[] was
replaced last week by a similar field in the transient itemizing bill.
At the time, the old field was left in place to avoid incrementing
EDITLEVEL.

shkp->mextra->bill[] is saved and restored, so its queuedpay field was
too.  Eliminate that no longer used field.

Unrelated:  bill[]->useup is declared as boolean but being assigned 1
or 0.  Change the assignments to use TRUE or FALSE.

41a5565403 new 'showvers' option
Add options 'showvers' (boolean) and 'versinfo' (numeric mask) to
show nethack's version on the status lines during play.  It won't be
particularly interesting to ordinary players but should be useful
when making screenshots or video to be streamed, or for someone who
switches between git branches or between nethack and variants.

I worked on this several months back but it was combined with
unfinished changes to 'hitpointbar'.  I've separated it out so that
it can be put into use.  When enabled, one or more components of
"<name> <branch> <version>" will be shown right justified after
status conditions.  At present the default is "<branch>" if that is
available and overall status isn't 'released', or "<version>" if
'released' or if branch isn't available.  That might need some
refinement.

It works as intended for tty and curses, although some abbreviation
mechanism would be useful if/when the program resorts to abbreviating
status conditions to make things narrow enough to fit.

For X11, it works ok for fancy_status:True (the default, controlled
via NetHack.ad settings) but is messed up for tty-style status.  The
text is positioned correctly but there are gaps in it, making it
appear garbled, similar to what I saw when I tried and failed to
implement statuslines:3 for X11.  [It might be due to having empty
condition widgets be 1 pixel wide instead of being totally removed
but I don't think the situation is that simple.]

For Qt, if the text needs to be truncated in order to fit, the center
portion of the string will be shown, discarding parts from the left
and right.  That ought to discard from left and retain rightmost
portion instead.

For win32|mswin|Win GUI, no attempt to support it has been included.
Things should be ok when 'showvers' is left as False (the default)
but I don't know what will happen if that gets toggled to True.  At a
minimum, the version info won't be right justified.  The information,
or at least some of it, is displayed in the game window's title bar
so there isn't any pressing need to add it to status, but toggling
the option will need to behave sensibly if it doesn't already.

Four kinds of timers are defined but only two have ever been used.
Have sanity checking complain if the other two occur or if 'kind'

Also, replacing a perfectly normal use of isok() with an inline test

0d508cc936 Implement the spellbook of chain lightning
Prior to this commit, there was no good way to deal with swarms of
weak, good-AC enemies using magic; trying to play a wizard as a
pure spellcaster would make bees and ants very difficult to deal
with (because they would usually dodge force bolts).

This commit adds a new spell designed to be very good against
swarms of weak enemies: "chain lightning", which does 2d6 lightning
damage to every monster around you. It has an initially short range,
but can chain from monster to monster to cover potentially large
distances (as long as none of the monsters en route are shock
resistant or tame/peaceful; the spell can't chain past shock
resistant monsters and avoids peacefuls). Monsters within one
space of the visible lightning bolts are affected. Unlike other
lightning effects, this one does only 2d6 damage, not enough to
blind affected monsters.

This commit breaks existing save and bones files (thus the
EDITLEVEL increase).

fb0509a6b3 fix #3841 - steed and engulfer on same map spot
Reported five months ago, a save was performed while a mounted hero
was engulfed.  Restore issued a warning about the engulfer being
placed on top of the steed (who shouldn't have been on the map).

The report arrived at about the same time as engulfing a riding
hero was changed to force a dismount instead of engulfing both hero
and steed so nothing further was done about it.  This changes
restore to not put a steed on the map and then take it off again.
It also attempts to simplify usteed and ustuck handling during save
and restore.

Testing so far indicates that things are still working correctly.

f9a35132d6 crystal helmet
Discussed a long time ago, change helm of brilliance from iron to
crystal so that it doesn't need to be a special case for metallic
armor's affect on spell casting.  It now has a fixed description of
"crystal helmet" but is not pre-discovered.

Add new helm of caution to retain the "etched helmet" description
among the shuffled helms.  Wearing it confers the Warning attribute.
That's fairly lame but not necessarily useless.  It's iron and gets
half the former probability for a random piece of armor being helm
of brilliance so is not likely to be popular.

Helm of caution keeps the old helm of brilliance tile and new helm
of brilliance is basically the same image with different color and
pointed on the top.

Not changed:  the etched helmet was marked as green and is drawn
that way for text but the tile doesn't actually use green for it.
Crystal helmet started as hi_glass (rendered as 'bright cyan') but
has been changed to clr_white to match crystal plate mail.
