Type fixes:

- Renaming or changing the schema for a shell type should not be allowed.

- I'm allowed to try to add ACL entries or security labels to an
existing shell type. This should be disallowed.

- Changing the schema on a (non-shell) type doesn't work - the type
name is omitted, e.g.

ALTER TYPE pem
    SET SCHEMA pemhistory;

Which should be:

ALTER TYPE pem.foo
    SET SCHEMA pemhistory;
