NFD

For test_tcp_udp_tunnel, the test appears to be failing either because nfdc could not create the face or because no Interests were received. test_localhop is failing because of nfdc. test_hub_discovery failed on nfd-status. test_interest_aggregation appears to be failing because it's receiving twice as many interests as it should be (either that or an error parsing the input). test_broadcast is failing because it's not receiving any interests when it should be.
