Prepare for the removal of set_rcvar() by changing the rcvar=
assignments to the literal values it would have returned.

The concept of set_rcvar() was nice in theory, but the forks
it creates are a drag on the startup process, which is especially
noticeable on slower systems, such as embedded ones.

During the discussion on freebsd-rc@ a preference was expressed for
using ${name}_enable instead of the literal values. However the
code portability concept doesn't really apply since there are so
many other places where the literal name has to be searched for
and replaced. Also, using the literal value is also a tiny bit
faster than dereferencing the variables, and every little bit helps.

Run load_rc_config before stop_cmd definition, so that ${quotaoff_flags}
is correctly expanded inside stop_cmd instead of getting nothing.

Substitute ypset for ypbind in REQUIRE lines. If you use ypset it has to
happen right after ypbind, and before anything that uses NIS. The only
change in rcorder accomplished by this patch is make that happen.

Make quota knob conform to other rc(8) knobs. Keep older knob for
compatibility.

Requested by: Volker <volker@vwsoft.com>

Remove spurious # marks to be more consistent with existing style.

Add the following knobs for quotas if they are enabled:

quotaon_flags - flags for the quotaon command
quotaoff_flags - flags for the quotaoff command
quotacheck_flags - flags for the quotacheck command

Remove the requirement for the FreeBSD keyword as it no longer
makes any sense.

This commit was generated by cvs2svn to compensate for changes in r78344,
which included commits to RCS files with non-trunk default branches.

Import the NetBSD 1.5 RC system.

Note that `rc' and `rc.shutdown' could not be imported because we already
have files with those names.
