lws minimal http server eventlib demos

This demonstrates a slightly more complex demo that can use any of the event loops (it defaults to poll)

It uses statically included plugins to provide the lws test server functions

Commandline option	Meaning
-d <loglevel>	Debug verbosity in decimal, eg, -d15
--uv	Use the libuv event library (lws must have been configured with `-DLWS_WITH_LIBUV=1`)
--event	Use the libevent library (lws must have been configured with `-DLWS_WITH_LIBEVENT=1`)
--ev	Use the libev event library (lws must have been configured with `-DLWS_WITH_LIBEV=1`)

build

 $ cmake . && make

usage

 $ ./lws-minimal-http-server-eventlib-demos
