Title: Fix configuration cache invalidation

Addresses several issues with configuration cache invalidation.
The symptom of these problems was that the cache was not
invalidated when it should have been.

Specifically:

Fixes an inconsistency between bash and other shell in which
the -ot test behaves differently when the left hand file does
not exist.

Fixes an issue with host name change detection on Mac OS.

Fixes an issue detect that dcache.conf was added.
