Integrate TLDK with NGINX
Created a clone of nginx (from https://github.com/nginx/nginx) to demonstrate and benchmark TLDK library integrated with real world application. A new nginx module is created and and BSD socket-like API is implemented on top of native TLDK API. Note, that right now only minimalistic subset of socket-like API is provided: - accept - close - readv - recv - writev so only limited nginx functionality is available for a moment.
