Add sys/unix/sysconf, a sample sysconf file.
Move defines from topten.c to config.h so they can be seen globally.
Add persmax, pers_is_uid, entrymax, and pointsmin to struct sysopt, use
in topten.c, populate in files.c
Warning cleanup in files.c.
BUGFIX: don't crash in unixmain.c if WIZARDS left unspecified.
hints/macosx10.5: don't hardcode "keni"; install sample sysconf; install
sample ~/nethackrc
makedefs: add "system configuration" to compiled-with options list.
BUGFIX: if a game doesn't meet the criteria for making the record file it's
shown to the user as having zero points because t1->points is set to zero
to indicate that it doesn't get written back; display u.urexp instead.
Add SHELLERS - people allowed to use ! command with same syntax as WIZARDS.
Add new hints file for 10.5, since the rules and commands for groups changed
(new commands introduced in 10.4, old ones removed in 10.5; creating a new
user under 10.4 gave you a matching group, in 10.5 it doesn't). Also move
shared build into roughly right place in file system when being installed
for root - don't use ~root.
Makefile.top - don't remove ./-p unless it exists (that's always annoyed me).
fix error invoking macosx.sh
Add MAXPLAYERS to SYSCF config file; deprecate (but continue to support)
MAX_NR_OF_PLAYERS in nethack.sh since it is trivially overridden in many
(all?) cases and isn't useful for ports that don't use nethack.sh.
infrastructure for "system options" - things currently specified at build
time that should be changeable at install time or run time but not really
under user control
generalize contact info so it can be localized and it doesn't have to be
an email address
move recently introduced WIZARDS into sysopt
drop bogus OPTIONS=wizards possibility
new function build_english_list() to comma-ize and add 'or' from a whitespace separated list: A. A or B. A, B, or C.
syscf file now handles: WIZARDS SUPPORT RECOVER
SUPPORT specifies local support information
RECOVER will eventually supply port-specific and/or localized info on how
to run recover (or get it run for you).
Note: in sys/msdos I changed sys.o (generated from pcsys.c) to pcsys.o
Note: sys/msdos/Makefile.GCC has 2 rules for sys.o (now pcsys.o)
