Fixed BUG#336: Subselects with tables does not work as values for local SP variables

Browse Source 
and BUG#1654: Stored Procedure Crash if contains subquery and set function

Disallowed subselects in RETURN (for FUNCTIONs) and SET of local variables.
The latter should work, but turned out to be difficult to fix, so we just
disallow it for the time being.
