Implement a BSD-licensed Multicast DNS responder and an accompanied
NSS (Name-Service Switch) module which provides integration with the
name resolver library.

Multicast DNS (mDNS) [1] is a part of Zero Configuration Networking (Zeroconf) and provides the ability to address hosts using DNS-like names without the need of an existing (unicast), managed DNS server.
