lws minimal ws client PING

This connects to libwebsockets.org using the lws-mirror-protocol.

It then sends a ws PING every 5s and records any PONG coming back.

build

 $ cmake . && make

Commandline Options

Option	Meaning
-d	Set logging verbosity
--server	Use a specific server instead of libwebsockets.org, eg `--server localhost`. Implies LCCSCF_ALLOW_SELFSIGNED
--port	Use a specific port instead of 443, eg `--port 7681`
-z	Send zero-length pings for testing

usage

Just run it, wait for the connect and then there will be PINGs sent at 5s intervals.
