Replace TupleTableSlot convention for whole-row variables and function

Browse Source 
results with tuples as ordinary varlena Datums.  This commit does not

groundwork for allowing composite types as table columns, and perhaps
some other useful features as well.  Per my proposal of a few days ago.
