persist_data: drop SQLData indirection

The common case (if not the only case) is to only use a single domain.  The
only reason SQLData exists is to make it easier to delete a domain.  Yet,
there's no need for us to delete a domain if SQLTable knows how to clear
itself out.  So, add clear() to the table and pass the domain to persist().
