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.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

debugging.)
Point out that a date specification _must_ follow the time of day
spec, in the man page. This clarifies the last point PR # of bin/483:
