Code review for range-types catalog entries.

Fix assorted infelicities, such as dependency on OIDs that aren't
hardwired, as well as outright misdeclaration of daterange_canonical(),
which resulted in crashes if you invoked it directly.  Add some more
regression tests to try to catch similar mistakes in future.
