93a2fe45a6 Allow time offsets to be negative, e.g. at 1530 - 15 minutes. 
This is useful if you have been given some time for some event in some
format and you want your computer to do something to prepare for it.
Without having to do time arithmetic in a shellscript.

The syntax matches what the at(1) usually used on Linux supports.

a35353de88 Partially revert r227233. 
The privs.h header is not only used by at(1), it's also used by
atrun(8). Just let the code the way it used to be (for now).

f64efe8b60 Add missing static keywords to at(1). 
While there, tidy up the privs.h part, where at.c has to #define to
declare some globals. Also group static and non-static global variables
in at.c.

ef636796f6 ANSIfy various tools in usr.bin/. 
Most of these tools properly build at WARNS=6, except for their K&R
function declarations. Fix this, so we can bump WARNS as well.

4ed7018006 While revision 1.26 fixed the code to really subtract 3600 due to 
daylight-saving, this was actually wrong because mktime() already does that for
us.

8b179749d8 #include <sys/time.h> instead of depending on namespace pollution in 
<sys/stat.h> for the declaration of struct timeval (sys/stat.h> only
needs timespecs even when its POSIX support is not turned on, so it
shouldn't declare timevals).

Fixed some #include messes.

9f5b04e925 Style improvements recommended by Bruce as a follow up to some 
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

cda2a9b2f0 Set BINOWN=root explicitly for setuid root binaries. 
This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want
these to be installed setuid root in this case.

9dd887f1a6 SECURITY. 
Fixed macros for temporarily relinquishing and restoring setuid/setgid
privileges so that they never change the real user and group IDs of
the calling process.

The setre[ug]id() calls are still used in the REDUCE_PERM macro (with
the r[ug]id arguments of -1) so that the call changes the saved user
and group IDs of the process to that specified.

Also, the panic() and perr() functions had insufficient privileges to
delete the problematic file under /var/at.

f4510294cb Y2K fix. at(1) would die with 'garbled time' when assign_date() was 
pased a year > 99.  This change fixes the conversion of 2-digit years
into tm_year format.

This change is differs from the OpenBSD fix because of differences
in our assign_date().
