usage

 $ ./lws-minimal-ws-server-timer
[2018/03/04 09:30:02:7986] USER: LWS minimal ws server | visit http://localhost:7681
[2018/03/04 09:30:02:7986] NOTICE: Creating Vhost 'default' port 7681, 1 protocols, IPv6 on

Visit http://localhost:7681 and the browser will connect back to the test server, you'll see ESTABLISHED logged. That triggers a TIMER event at 20s intervals which sets the wsi timeout to 60s. It should just stay like that forever doing the TIMER events at 20s intervals and not sending any traffic either way.
