Unfortunately, the existing networking API (common/network_utils.h)
lacks the UNIX domain socket support, and it turned to be easier
to implement a simple, single client server using Boost.Asio.
The server runs in its own thread with a blocking Tx queue, and
calls a user definted callback on receipt of any data from client.
Multiple client connections are not supported and will be rejected.
