Use 'load_rc_config_var CMD VAR' to set VAR for "foreign" rc.conf(5)
variables that may be set in /etc/rc.conf.d/CMD instead of /etc/rc.conf.
Fixes PR 20768 from Pavel Cahyna.

Use new style command substitution.

Explicitly REQUIRE: rpcbind since these services directly use RPC...

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.

- 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: 1.4.2;
* Portmap is now called rpcbind.
* Add IPv6 RPC entries to inetd.conf (commented out by default, as the others)
* Add netconfig file, needed for TI-RPC code.

branches: 1.3.2;
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.

fix check for domainname since it can come from /etc/defaultdomain as well as $domainname

branches: 1.1.1;
Initial revision

rc.d scripts derived from /etc/rc

Sync w/ netbsd-1-5-base.

pull up rev 1.5 (approved by thorpej):
- always use $rcvar to determine the name of the var to checkyesno
- fix force*

Pull up revision 1.10 (requested by lukem in ticket #1269):
Use 'load_rc_config_var CMD VAR' to set VAR for "foreign" rc.conf(5)
variables that may be set in /etc/rc.conf.d/CMD instead of /etc/rc.conf.
