Copy stable/9 to releng/9.3 as part of the 9.3-RELEASE cycle.

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.

Remove trailing white space. No functional changes.

Let rc and periodic infrastructure and newsyslog use the utmpx files.

As previously discussed, add the svn:executable property to all scripts

Remove two superfluous trailing semicolons.

Add a dummy script, FILESYSTEMS, which depends on root and mountcritlocal
and takes over mountcritlocal's role as the early / late divider. This
makes it far easier to add rc scripts which need to run early, such as a
startup script for zfs, which is right around the corner.

This change should be a no-op; I have verified that the only change in
rcorder's output is the insertion of FILESYSTEMS immediately after
mountcritlocal.

Clear up problems with /etc/rc.d/{abi|cleanvar|cleartmp} brought
to light by the PR. Specifically, convert these three scripts
into good rc.d citizens, making sure that their functionality
is preserved, but the rc.d framework rules are not broken.

Add support for cleanvar as a regular rc.d script in the
default rc.conf, and document this in the man page.

Add a descriptive comment to rc.conf that regarding the
three emulation/compatibility services provided by abi
so users will not be confused by these services not having
their own startup scripts.

Back-out previous commit - we need to skip logging socket when we start a
jail and external syslogd is listening in jail's chroot.

Pointed out by: csjp

While here, skip also "logpriv" socket.

We don't need to skip /var/run/log socket, as syslogd is always started
after rc.d/cleanvar. And if we wanted to skip /var/run/log we still needed
to skip /var/run/logpriv, which wasn't implemented.

Do not remove logging sockets. This fixes an issue where logging
sockets placed into prisons from the host environment get clobbered
by the prison's instance of cleanvar. (assuming /etc/rc is run in
the prison).

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

Overhaul the /etc/rc.d/diskless script by splitting it out into
hostname, resolve, tmp, and var scripts. The latter three are new and
were repo copied. These scripts no longer depend on being booted with
and NFS root instead attempt to automaticly create mfs /tmp and /var
volumes if the they are not writable. This behavior can be overridden
in /etc/rc.conf.

Make sure ipmon is run after cleaning up in /var. Otherwise,
we would lose it's pid file. Also, cleanup the depencies in
rc.d/cleanvar

o Hook the new files up to the build.
o Make sure all the scripts reference rc.d/netif and not rc.d/network1

When cleaning /var/run make sure the control files are not removed
unconditionally when the script is being rerun (when it is called
with the reload argument).

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.
