Add a new builtin type, "uuid". This implements a UUID type, similar to

that defined in RFC 4122. This patch includes the basic implementation,
plus regression tests. Documentation and perhaps some additional
functionality will come later. Catversion bumped.

Patch from Gevik Babakhani; review from Peter, Tom, and myself.
