Andy Green b68152e1e5 travis: restrict spam connections 
Travis seems to be restricting the number of outgoing connections
or the rate of them... we have been using 10 concurrent and 100 connections

Reduce to 3 concurrent / 15 see if it helps travis get over the hump

lws minimal ws client SPAM

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

By default is has 10 concurrent connections and connects 100 times.

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
-c Amount of concurrent connections
-l Test limit (total number of connections to make)

usage

Just run it, it will repeatedly connect and reconnect to libwebsockets.org until it hits the test limit.

You can also direct it to use the lws test server in tls mode by running that with libwebsockets-test-server -s and running this using, eg

 $ ./lws-minimal-ws-client-spam -c 20 -l 200 --server localhost --port 7681

 $ ./lws-minimal-ws-client-spam
