If a plpgsql function is declared to return a domain type, and the domain's constraints forbid a null value, it was nonetheless possible to return NULL, because we didn't bother to check the constraints for a null result. I'd noticed this while fooling with domains-over-composite, but had not gotten around to fixing it immediately. Add a regression test script exercising this and various other domain cases, largely borrowed from the plpython_types test. Although this is clearly a bug fix, I'm not sure whether anyone would thank us for changing the behavior in stable branches, so I'm inclined not to back-patch.
