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

- 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 '# KEYWORD: shutdown' so that these scripts get run at shutdown time.
now, only scripts with the keyword `shutdown' will be run by /etc/rc.shutdown,
which speeds up shutdown and makes it more robust.

Use load_rc_config() (from rc.subr) instead of sourcing /etc/rc.conf.
This allows us or a user to change the configuration file method in
one place - rc.subr - without having to edit all of the rc.d/* files.

use extra_commands= instead of using 2nd argument to run_rc_command

* replace daemon, login, servers with DAEMON, LOGIN, SERVERS
* remove sshd (it was from my private system)

summary:

* reword descriptions
* add '# KEYWORD: shutdown' to some of these scripts so that only they get run
at shutdown time. now, only scripts with the keyword `shutdown' will be
run by /etc/rc.shutdown, which speeds up shutdown and makes it more robust
* 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
* move recreating /var/run/utmp from mountcritlocal (where /var/run is
purged but /usr/bin/install is not available) to sysdb.
problem noted by Matthias Drochner.
* share the same load_rc_config between the lkm* scripts
* network: Don't warn that $hostname isn't set if the hostname is already set.
* network: reenable stop_cmd now that network doesn't get run at shutdown
* add sshd startup script
* use "load_rc_config swap" for swap1 and swap2
* syslog requires databases from sysdb which creates /var/run/utmp.
