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.
