Allow empty domain names to be decoded
...
This is a rather long standing issue. LibDNS didn't allow to decode empty domain names. Empty domain names were previously only observed with PTR records, but were now also observed in regular queries in authoritative records that include the root nameservers.
LibDNS 2.0 mainly adds scalar types has just a few breaking changes. We don't expose it anywhere, so an upgrade is perfectly fine.
Fixes #53 .

Fix BasicResolver::resolve to break redirect loop
...
Previously we queried domains usually five times (max redirects). It didn't have much impact, because these records were usually cached and immediately returned again, but this resulted in the TTL always being NULL due to cached records being returned.

Use random IDs and different UDP ports for each request
...
This is another countermeasure as outlined in https://tools.ietf.org/html/rfc5452 . Request IDs have 16 bits of entropy now. The port will change during requests, but is usually not random. However, there are systems that use a random port for :0 port requests.
