Use load_rc_config `basename chrootdirscript` in a subshell to determine
the rc.conf(5) setting for chrootdirscript, incase the configuration
for that is in /etc/rc.conf.d/chrootdirscript.
Fixes PR 26478 from Jukka Salmi.

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

Build the list of names to check for $XXX_chrootdir support from
`rcorder -k chrootdir` rather than hardcoding "named ntpd".

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.

- Rename a bunch of "internal" run_rc_command() variables and officially
make them "externally" available:
Previous Current Purpose
-------- ------- -------
_arg rc_arg Argument to command, after fast/force
processing performed (and prefix
removed)

_flags rc_flags Flags to start the default command
with. Defaults to ${name}_flags,
unless overridden by $flags from the
environment. This variable may be
changed by the precmd method.

_pid rc_pid PID of command (if appropriate).

_rc_run_fast rc_fast Not empty is "fast" was provided.

_rc_run_force rc_force Not empty is "force" was provided.

- Use rc_flags instead of _flags or ${name}_flags in various rc.d scripts,
so that $flags from the environment overrides ${name}_flags from rc.conf(5).
Fixes [bin/15800].

oops; forgot to retain previous setting of $_flags (aka $syslogd_flags)
which adding "-P /var/run/syslogd.sockets"...

* build /var/run/syslogd.sockets to contain list of sockets in chrooted cages
that we know about, and start syslogd with -P /var/run/syslogd.sockets
if necessary.
* add ${ntpd_chrootdir}/var/run/log to known sockets

if $named_chrootdir is defined, add ${named_chrootdir}/var/run/log to
the list of sockets listened to.

- 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

syslog requires databases from sysdb which creates /var/run/utmp.

* 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)

Add "wscons" to requirement list so that a tty used for syslog output
will be created before starting the syslog daemon.

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

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.
