lws minimal http Server Side Events + ringbuffer

This demonstates serving both normal content and content over Server Side Events, where all clients see the same data via a ringbuffer.

Two separate threads generate content into the ringbuffer at random intervals.

build

 $ cmake . && make

usage

 $ ./lws-minimal-http-server-sse

Visit http://localhost:7681, which connects back to the server using SSE and displays the incoming data. Connecting from multiple browsers shows the same content from the server ringbuffer.
