deraadt and millert ok

long-standing annoyance that atrun's granularity is 10 minutes.
Most at jobs run with a 1 minute granularity.  Jobs submitted via
"at now" or "batch" will run immediately.  Includes a rewritten
cron(8) man page.  at(1) will be integrated more closely into
cron at a future date.
Upgrading notes:
the atrun job in root's crontab should be removed.
the /var/at/spool directory is no longer used

ok henning@, deraadt@

hi mom, i'm in jail!

that the first char in the line is not NUL after killing comments.

ok frantzen@

field separators as empty field.  This is not what we want for
whitespace-delimited fields.

o make first arg const since we don't modify it
o use strsep() instead of strtok() as strtok() changes internal state
o add some bounds checking and use strlcat() instead of pointer arithmetic
o ANSI function headers
Originally based on a patch from Lars J. Buitinck but much modified.

generic as /dev/smartcard or similar.
deraadt@ ok.
