Graham Campbell 820c014578 cfilters: fix event-based connection shutdown
- Adjust pollset during connection shutdown.

- Separate the FIRSTSOCKET and SECONDSOCKET check so that one being in
  connect or shutdown no longer adds poll events for the other.

- Fix shutdown state evaluation (as detailed below).

- Add a unit test for Curl_conn_adjust_pollset.

- Add a client for event testing.

- Test that shutdown sockets stay with the socket callback until done.

The pollset predicate now reads the connection's own shutdown state
rather than going through data->conn, and the EXPIRE_SHUTDOWN arming in
cshutdn_perform() works again: next_expire_ms started at 0 and could
never be set, so a peer that never sends a close_notify would still park
its connection forever, timeout or not.
