Overhaul the /etc/rc.d/diskless script by splitting it out into

hostname, resolve, tmp, and var scripts.  The latter three are new and
were repo copied.  These scripts no longer depend on being booted with
and NFS root instead attempt to automaticly create mfs /tmp and /var
volumes if the they are not writable.  This behavior can be overridden
in /etc/rc.conf.
