don't ignore errors from read(); found by lint

Assorted minor cleanups, no functional change:
- u_int* -> uint*
- don't make private typedefs of system structures
- use curses TRUE and FALSE only with curses booleans, otherwise
true and false;
- includes cleanup
- group globals in extern.c by functionality

Object file diffs inspected.

Whitespace.

ANSIfy. Use __dead. Object diffs checked.

If getpwuid() returns null, its not usually a good idea to dereference
that to try to assign a default value. Just copy the default value into
the final destination.
Addresses Coverty CID 925

Remove uses of __P.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22269, verified by myself.

Cast pointer diffs to long for printing with %ld.

Fix arguments to *printw().

Don't insert leading 0s in the score display. (HI CHRISTOS!)

Report scores as auto-bot or not correctly.

Bug report and fix from Malcolm Parsons <malcolm@bits.bris.ac.uk>.

Fix -Wsign-compare warnings.

Security improvements for games (largely from or inspired by OpenBSD).

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.

Use the symbolic names `SEEK_SET' and `O_RDONLY' where appropriate in
the games.

Add use of `const' where appropriate to the games.

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).

Some such changes were previously covered in PRs bin/6041, bin/6146,
bin/6148, bin/6150, bin/6151, bin/6580, bin/6660, bin/7993, bin/7994,
bin/8039, bin/8057 and bin/8093.
