for some time now mandoc has not required MLINKS to function
correctly - logically complete that now by removing MLINKS from base;

authors need only to ensure there is an entry in NAME for any function/
util being added. MLINKS will still work, and remain for perl to ease
upgrades;

Use absolute paths in pathnames.h. There is no longer a need to
chdir(2) to the cron dir and cron(8) now changes to / via daemon(3).
We no longer try to create/chmod the spool directories as they
should be set correctly at install time. The setegid(crontab)
has been moved to open_socket() so it is closer to the chmod(2)
call that needs it. OK deraadt@ tedu@

Split client-only (at, crontab) functions out of misc.c and into
client.c. Move truly common functions into common.c. This avoids
dead code in the at and crontab commands.

don't need to define debugging 0 anymore

Sync with ISC cron-current + my at(1) integration.
The at(1) code is now more tightly integrated into the cron codebase.

Move atrun(8) functionality into cron(8) proper. This fixes the
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

Major changes:

Job names are now "runtime.queue" where runtime is when the job will run
in Unix time format. This is what SysV at does and allows us to nuke
the .SEQ file.

Historic BSD options for atq and atrm are now implemented;
atq and atrm get their own man pages.

At no longer does anything with the -v flag. We print the execution
time when jobs are submitted so there is no need.

Most *scanf() usage is gone (one remains in atrun).

Better sanity checks in atrun.

Random style/cleanup.

With these changes we have the best of both worlds; POSIX compliance with
the traditional BSD features.

at(1) is no longer setuid root, it is setgid crontab.
This means that /var/at/at.{allow,deny} must be readable by group
crontab, /var/at/jobs is mode 01770, and /var/at/.SEQ is mode 0660.
