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. Reviewed by: luigi, pjd
