Jan de Visser 7ea54db430 LibSQL: Add 'schema' and 'table' to TupleElementDescriptor
These are needed to distinguish columns from different tables with the
same column name in one and the same (joined) Tuple. Not quite happy
yet with this API; I think some sort of hierarchical structure would be
better but we'll burn that bridge when we get there :^)
