Address LinkLocal issues
Generation of TXT records might fail if any of the fields is too long,
so the result is now an optional (pending Expected). Callsites have been

Three potentially uncaught exceptions in the Bonjour implementation have

Test-Information:
Unit tests pass on macOS 10.14 and Debian 9
