Clean up handling of tuple descriptors so that result-tuple descriptors
allocated by plan nodes are not leaked at end of query. This doesn't really matter for normal queries, but it sure does for queries invoked repetitively inside SQL functions. Clean up some other grotty code associated with tupdescs, and fix a few other memory leaks exposed by tests with simple SQL functions.
