Improve reporting of permission errors for array types
Because permissions are assigned to element types, not array types,complaining about permission denied on an array type would bemisleading to users. So adjust the reporting to refer to the elementtype instead.In order not to duplicate the required logic in two dozen places,refactor the permission denied reporting for types a bit.pointed out by Yeb Havinga during the review of the type privilegefeature
