Fix format string warning in robots/score.c

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

high scores printed too far to the right, move it left a little

More cleanup and sorting on header section

OK tb@ and he also pointed out that for consistency with rest of the tree we
should include termios.h instead of sys/ttydefaults.h, where applicable

Drop pledge("getpw") and pwd.h and use the now usual
LOGNAME -> USER -> getlogin() -> ??? fallback
in the score file, as requested by tedu@

Man page bits adapted from jmc@'s tweaks to snake.6

Move scorefile to $HOME. The nice implementation of the score file
depends on getpwuid(), so add "getpw" to the rest of the required
pledges: "stdio rpath wpath cpath tty".

Eliminate pointless use of <sys/param.h>, <sys/file.h>, <sys/sockio.h>,
and <sys/ttydefaults.h>
Replace MAXPATHLEN with PATH_MAX and MAXLOGNAME with LOGIN_NAME_MAX
Pull in <limits.h> where needed
Prefer sizeof(var) over MAXFOO or FOO_MAX

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

ansi. ok deraadt@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

de-register

Enable realtime mode, use native curses functions when available, tidy man
page, and use MAXLOGNAME for scorefile (this makes new scorefiles incompatible
with old ones). Realtime idea and some code from d@.

More largely NetBSD-inspired code cleanup

Scorefile bugfix and minor code cleaning, some from NetBSD

add tags to changed files

fix highscore without breaking security
