Don't cross mount boundaries when cleaning tmp files.

Mounting something in /tmp such as a build jail with nullfs mounts for
some directories can result in very surprising results the next day.

Don't remove empty dirs if their names are in $daily_clean_tmps_ignore

When considering temporary files for deletion, don't examine the mtime
and atime only, but also the ctime. Otherwise, files extracted from
tar or zip archives will immediately be declared stale since they've
got their mtime reset to the original mtime.

Another overhaul of the periodic stuff.

All periodic sub-scripts <larf> now have their return codes interpreted
by periodic(8). Output may be masked based on variable values in
periodic.conf.

It's also now possible to email periodic output to arbitrary addresses,
or to send it to a log file, examples of which can be found in
newsyslog.conf.

The upshot of it all should be no discernable changes to the default
behaviour of periodic(8).

PR: 21250

Introduce /etc/defaults/periodic.conf, similar in concept to rc.conf.
The only change in the default functionality should be that
the output reports are slightly more verbose WRT files deleted.

Not objected to by: freebsd-arch

Use $clear_daily_* from rc.conf to decide what should be deleted

Don't delete quota files when clean-tmps is enabled.

Finally remove the ancient `-exec rm -f {} ;' cruft that used to be
used to cleanup old files, and replace it by -delete which has been
present in our find(1) for ages now.

Copy /etc/cron.d to /etc/periodic per-request of many.
This wasn't done with a repository copy because there was no
history of any consequence. Flames to me.
