If we panic again shortly after boot (say, within 30 seconds), any core
dump we wrote out may be lost on reboot. In this situation, we really
want to keep that core file, as it may be the only way to have the issue
resolved. Call sync(8) after writing out the core file and running
crashinfo(8), in the hope that these will not be lost if we panic
again. sync(8) is only called in the case where there is a core dump
to be written out, so won't be called during normal boots.

space configured for rc.d/dumpon to designate for dumping -- then exit
silently rather than with a
> realpath: /dev/dumpdev: No such file or directory
error message.
An argument could be made that we should print a (more informative) warning
message; but given that under the same conditions the rc.d/dumpon script will
already print a
> No suitable dump device was found
warning, it seems that printing an additional
> Dump device does not exist. Savecore not run.
warning would be superfluous.

provide dump directory. Eliminate this redundant argument. This changes
the usage, but the only risk here is that a warning will be printed
about directory given as device.
- Update usage of -C option.
- When clearing dump header from the given device there is also no need to
provide dump directory, although additional arguments for -c were not
documented.
- Document that -v can be used with -c and that list of devices can be given.

FILESYSTEMS (the default early_late_divider):
1. Move sysctl to run first
2. Move as many BEFOREs to REQUIREs as possible.
3. Minor effect, move hostid_save from right before mdconfig to right
after.
A lot of the early scripts make use of sysctl one way or another so
running this first makes a lot of sense given that system-critical
values are often placed in sysctl.conf.
My original purpose for working on this was that while doing some
debugging on other stuff I noticed that the order of execution was
different in the first pass through the early scripts and the second.
In practice that doesn't matter because the scripts are not executed the
second time. However this _can_ result in problems if the difference in
the rcorder moves a script from the late section to the early section in
the second pass (which would mean the script would not get executed).
So, I wanted to make the order of execution of the scripts in the early
section more deterministic.
In the course of debugging the ordering problems I noticed that moving
the BEFOREs to REQUIREs prevented the changes in order from the first
pass to the second pass without having to make any substantial changes.
(Of course it's no secret that I think BEFORE should be avoided as much
as possible, but this is a good example of why.)

employ a more generic solution, and use it in the individual rc.d scripts
that also have an $rc_quiet test:
1. Add check_startmsgs() to rc.subr.
2. In the rc.d scripts that use rc_quiet (and rc.subr) substitute
variations of [ -z "$rc_quiet" ] with check_startmsgs
3. In savecore add a trailing '.' to the end of the message to make it
more consistent with other scripts.
4. In newsyslog remove a : before the terminal '.' since we do not expect
there to be anything printed out in between to make it more consistent.
5. In the following scripts change "quotes" to 'quotes' where no variables
exist in the message: savecore pf newsyslog
6. In the following scripts substitute if/then/fi for the simpler (and
more consistent) check_startmsgs &&: faith stf
7. In the following scripts separate the "Starting foo:" from the terminal
'.' to make them more consistent: moused hostname pf
8. In nfsclient move the message to its own line to avoid a style bug
9. In pf rc_quiet does not apply to the _stop method, so remove the
test there.
10. In motd add 'quotes' around the terminal '.' for consistency

The NetBSD ident string will be left intact, both for history and
