Adjust to "pool" usage in our standard ntp.conf, pointed out
by Connor McLaughlan.

Explicitly set a BEFORE on ntpd, as this can't run while ntpd is
running.

Apparently it is rare for rcorder to place it after ntpd but there was
previously nothing actually preventing it.

Fixes PR 40707 by Ondrej Tuma

ntpdate can't work without named because a modern ntp.conf has dns
names in it. We therefore now depend on it.

However, this would have then created a circular dependency because named
depended on "SERVERS", and racoon was before SERVERS and required kdc,
and kdc needs the time to be right and thus depended on ntp.

Instead, have named depend on NETWORKING (so that there is a network
there), mountcritremote (so we know that named has a directory to work
from) and syslogd (so that named has some place to spew information).

I'm not sure this is perfect, but it is certainly a big improvement
over constantly failing ntpdate runs during boot.

Explicitly REQUIRE mountcritremote, since this uses awk.

Use new style command substitution.

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

ntpdate to a multicastclient address doesn't work

Make the ntp.conf parsing more specific, and therefore more robust. Closes
PR bin/23305.

Supply the usual default setting of $commmand. Omission pointed out by
Launey Thomas in private mail.

Allow for a syntax extension for "ntp.conf" with ntp 4.2.0.

Use "$command", instead of hard-coded "ntpdate", so that the user can
override the path using the usual mechanisms.

Support "multicastclient" directives in ntp.conf.
Based on [bin/17930] from Stoned Elipot.

Ignore "peer" statements for local clocks too when selecting hosts from
ntp.conf.

- 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].

Rename NETWORK to NETWORKING, to allow rc.d to be on a case insensitive
file system (prevents conflict with 'network'). PROVIDE both NETWORKING
and NETWORK (the latter for compatibility with 3rd party scripts).

- 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

Move options into ntp_flags, to make it possible to add '-u' without
modifying rc.d/ntpdate

* 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)

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.

Add missing checkyesno's.
