I've added in the inet/cidr types to the regression test, using mostly
the tests that D'Arcy sent. Just changed the layout a bit to conform to
the other tests and added a test or two to do equality comparisons.
D'Arcy et al, could you follow up and augment those tests, either now if
it's easy or for v6.5? Probably better to wait a bit as we learn more
about the types and their expected behaviors.
All regression tests pass on my Linux/i686 machine.
