MFC: r240336:
Simply things so that "#REQUIRE: FILESYSTEMS" means the file
systems are fully "ready to go".

'FILESYSTEMS' states: "This is a dummy dependency, for services which
require file systems to be mounted before starting." However, we have
'var' which is was run after 'FILESYSTEMS' and can mount /var if it
already isn't mounted. Furthermore, several scripts cannot use /var
until 'cleanvar' has done its thing. Thus "FILESYSTEMS" hasn't really
meant all critical file systems are fully usable.

MFC r230099:

Change rcvar= assignments to the literal values set_rcvar
would have returned. This will slightly reduce boot time,
and help in diff reduction to HEAD.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

In regards to the "Starting foo:" type messages at boot time, create and
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

Move a lot of diagnostic output behind $rc_quiet in scripts that
implement their own start command.

Remove $NetBSD$ CVS tags. We no longer attempt to synch our rc.d files
with theirs, so this information doesn't need to be in the live file.
Having it in our CVS history is enough.

syslogd should REQUIRE newsyslog, rather than newsyslog using
BEFORE: syslogd. This does not produce any change in the
ordering at the moment, but is cleaner style for the long term.

Use ${name} in pathnames where appropriate.
The sendmail script already was on this way,
but it didn't reach the end of it yet.

- Update etc/rc.d/newsyslog to FreeBSD standards and install it.
- Enable it by default, running newsyslog with -CN which creates files
that have the C flag specified in /etc/newsyslog.conf.
- Remove the "newsyslog -CC" call from etc/rc.d/var and the check for
newsyslog.
- Add the C flag to entries in /etc/newsyslog.conf that are currently
installed as part of the base system.

There are two effects from this change:
- Users who delete default syslog files to stop logging to them
will need to set newsyslog_enable=NO in rc.conf or remove the C
flag from those file in /etc/newsyslog.conf or they will come back
on the next boot.
- Diskless systems now create the same set of files that ordinary
systems have by default instead of every file in newsyslog.conf.

Merge in all the changes that Mike Makonnen has been maintaining for a
while. This is only the script pieces, the glue for the build comes next.

Import the NetBSD 1.5 RC system.

Note that `rc' and `rc.shutdown' could not be imported because we already
have files with those names.
