From: Geliang Tang <geliang.tang@xxxxxxxx>
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]
