Doug Barton 57e561c083 Remove rcconf.sh from /etc/rc.d, and instead load the configuration
as part of rc. Doing this, and the sourcing of rc.subr after we have
determined if we are booting diskless (and correspondingly run
rc.initdiskless if necessary) are safe, and actually allow fewer files
to be needed on the diskless box. This also allows variables from
the configuration to be available to rc itself, such as ...

Add a variable to rc.conf, early_late_divider, which designates the
script which separates the early and late stages of the boot process.
Default this to mountcritlocal, and add text to etc/defaults/rc.conf,
rc.conf(5) and diskless(8) which describes how and why one might want
to change this.
