Make a ": " suffix a fixed part of the release info tag

This results in correct updates to /etc/motd even when the value of
motd_release_tag is changed (a likely event).

Add safe quoting to outputting the read kernel version.

Thanks to kre@ for the feedback.

Add an _rc_subr_loaded variable, set to ":" by rc.subr. Scripts can use this
for a speedup by doing:
$_rc_subr_loaded . /etc/rc.subr

Correct the "direction" of the barrier dependencies (DAEMON, LOGIN,
NETWORKING, and SERVERS) by specifying that certain things should
come BEFORE a given barrier, rather than having the barrier REQUIRE
a service. This allows scripts to be removed without having to
edit the barrier dependencies.

As discussed on tech-userlevel, and approved by Luke.

wrap file creation operation in: ( umask 022 ; <command...> )

- Remove extra 'rm -f' since file redirect safely clobbers existing files.
- Remove one sed invocation replacing it with shell internal construct.

- only perform the checkyesno on the variable named in $rcvar (rather than
implicitly using $name if $rcvar isn't set), and always perform this check,
even when using start_cmd (et al).

- only perform the checkyesno on the variable named in $rcvar (rather than
implicitly using $name if $rcvar isn't set), and always perform this check,
even when using start_cmd (et al).
this check is performed before the pidcmd
is run, speeding up scripts that weren't going to be run anyway.
this should speed up booting slow systems.

- take advantage of the above and remove
start_precmd="checkyesno foo"
in scripts that use start_cmd.

- explicitly set rcvar=foo in the rc.d/foo scripts which have an equivalent
rc.conf entry

- fix `rcvar' and `restart' when $rcvar isn't set.
these above changes fix PR [bin/11027].

- when doing `force*', ignore the return value of *_precmd.
this fixes PR [bin/10781].

- rename what sysdb provides from `databases' to `sysdb', to reflect
the name of the script.

- improve the comments in rc.subr

* add new dummy dependancy `NETWORK' to be REQUIREd by services which need
networking to be operational before starting, and use as appropriate.
NETWORK depends upon network and dhclient.
* move the guts of systemfs into mountcritlocal
* replace the dependancy on systemfs with mountcritremote, and remove the
former.
* SERVERS now also depends upon ppp

Notes:
* dhclient (and others) needs /var to be a $critical_filesystem_beforenet
* dhclient now starts before syslogd (because the latter needs /usr, and
/usr might need dhclient to be mounted)
