dougb c9292fd995 Clear up problems with /etc/rc.d/{abi|cleanvar|cleartmp} brought
to light by the PR.  Specifically, convert these three scripts
into good rc.d citizens, making sure that their functionality
is preserved, but the rc.d framework rules are not broken.

Add support for cleanvar as a regular rc.d script in the
default rc.conf, and document this in the man page.

Add a descriptive comment to rc.conf that regarding the
three emulation/compatibility services provided by abi
so users will not be confused by these services not having
their own startup scripts.
