This patch adds test coverage for listening sockets created by userspace processes.
It adds a new test named test_listener() and a new verifying helper verify_listener_events(). The new output looks like this:
CREATE_SUBFLOW 10.0.2.2 (ns2) => 10.0.2.1 (ns1) [OK] DESTROY_SUBFLOW 10.0.2.2 (ns2) => 10.0.2.1 (ns1) [OK] MP_PRIO TX [OK] MP_PRIO RX [OK] CREATE_LISTENER 10.0.2.2:37106 [OK] CLOSE_LISTENER 10.0.2.2:37106 [OK]
