Implement TCP support in the `ans11` Python-based DNS server. Implement a control command channel in `ans11` to support an optional silent mode of operation, which, when enabled, will ignore incoming queries. In the added check, make the `ans11` the NS server of "a.root-servers.nil." for `ns3`, so it uses `ans11` (in silent mode) for the regular (non-forwarded) name resolutions. This will trigger the "hung fetch" scenario, which was causing `named` to crash.
