Merge pull request #55 from rlane/barrier-after-delete

testutils: send barrier after deleting all flows
update pyloxi to 46b7804026447644fec44c0ad517b41844eeb91b
testutils: support of13 in delete_all_flows
testutils: remove incompatible wildcard check for OF 1.3

This needs to be replaced with code that uses the table features reply to
determine the fields that cannot be matched.
testutils: update port_config_get/set for OF 1.3
testutils: update verify_packet_in for OF 1.3
testutils: update get_stats to support OF 1.3
add basic OF 1.3 tests

Many of these tests were ported from the CPqD fork of oftest.

I've been running them against ofsoftswitch13. All pass except for
PacketInMiss.
