With the advent of elf and mmaping malloc, assumptions that the code made
before about location and contents of the data segment broke. We supplied
an sbrk() only malloc, and recorded the break point at the beginning of
the program, so now save and restore works, in the traditional monop style.
macro). Add new fwrite_be_offt() function which writes out a big-endian
64bit number regards of the size of off_t on the host machine.
Also fix ``bug'' in previous - even though the off_t pointers were
stored big-endian, the individual card lenghs were in host-order. The
cards.pck files are now identical when make on a big- or little-endian
machine.
Now builds a correct cards.pck file on non-NetBSD machines as well
- tested on Ultrix and Solaris (but Solaris needs -lsocket to get
htonl()).
Games which run setgid from dm, but don't need to, should drop their
privileges at startup.
Games which have a scorefile should open it at startup, then drop all
privileges leaving just the open writable file descriptor. If the
game can invoke subprocesses, this should be made close-on-exec.
Games with scorefiles should make sure they do not get a file
descriptor < 3. (Otherwise, they could get confused and corrupt the
scorefile when using stdin, stdout or stderr.)
Some old setuid revokes from the days of setuid games change into gid
revokes.

This merges in all such remaining changes from the Linux port of the
NetBSD games, except in hunt (where substantial changes from OpenBSD
need to be looked at).
Most noreturn attributes were previously added in bin/6144, with some
others that were missed then in bin/8082. Previous `unused'
attributes were covered in bin/6557, bin/8058 and other PRs (all these
PRs have already been handled and closed).

of the card decks file, just write out the number of cards for each
deck. Also use "off_t" for offsets into the file (that are stored after
the number of cards) instead of "long".
/usr/share/games/cards.pck is now MI.
