Add flag field to struct gb_operation, and a first flag GB_OPERATION_FLAG_INCOMING to identify incoming operations. Pass an initial set of flags when allocating new operations, and use these to identify incoming operations rather than overloading the meaning of GB_OPERATION_TYPE_INVALID. This also allows us to set the type for all operations during allocation. Also add convenience helper to identify incoming operations.
