Add an xpt_rescan function and a thread that will field
rescan requests. The purpose of this is to allow a SIM
(or other entities) to request a bus rescan and have it
then fielded in a different (process) context from the
caller.

There are probably better ways to accomplish this, but
it's a very small change that helps solve a number of
problems.
