Andy Green bce8cca042 refactor: also migrate tls to the ops struct and private.h pattern 
Several new ops are planned for tls... so better to bite the bullet and
clean it out to the same level as roles + event-libs first.

Also adds a new travis target "mbedtls" and all the tests except
autobahn against mbedtls build.

lws minimal ws proxy

Build

 $ cmake . && make

Description

This is the same as minimal-ws-server-ring, but with the inclusion of a ws client connection to https://libwebsockets.org using the dumb-increment protocol feeding the ringbuffer.

Each client that connect to this server receives the content that had arrived on the client connection feeding the ringbuffer proxied to their browser window over a ws connection.

Usage

 $ ./lws-minimal-ws-proxy

Visit http://localhost:7681 on multiple browser windows

Data received on the remote wss connection is copied to all open browser windows.

A ringbuffer holds up to 8 lines of text in the server, and the browser shows the last 20 lines of received text.
