701. [func] Root hints are now fully optional. Class IN

Browse Source 
views use compiled-in hints by default, as
                        before.  Non-IN views with no root hints now
                        provide authoritative service but not recursion.
                        A warning is logged if a view has neither root
                        hints nor authoritative data for the root. [RT #696]
