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

move ipmon's "-D" argument from "command_args" to "ipmon_flags" so that
passing an (optional) filename argument (that must come last) works fine
from $ipmon_flags. from PR#25006.

Revert previous:
+ it was not discussed first
+ it is not consistent with the rest of the rc.d system. everything else:
- has defaults & example configuration in /etc/defaults/rc.conf
- uses lower-case variable names, including ipmon itself

Similar functionality added by the change I'm backing out may be
reintroduced in the future once it's been changed to meet our de-facto
rc.d standards, as opposed to something that appears to have been
lifted from a non-NetBSD source (HP/UX ?) ...

load_rc_config needs to be called earlier to pickup the variables from the
config file so they can be used in the rc script itself.

Modify the script to use variable names provided by the ipmon conf file to
enable/disable "key" features.

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.

ipmon: set -D via command_args rather than the default ipmon_flags.
resolves [install/15753]

Start "ipmon" with option "D" for daemon mode instead of starting it
in a subshell.

- 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

branches: 1.2.4;
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.
