o Tsig will probably become an interface which has all configuration
  stuff, but this will come later. Config which has Tsig function

Todo:
* Parsing from strings, going with goyacc and .cz lexer?
* encoding NSEC3/NSEC bitmaps, DEcoding works
* HIP RR (needs list of domain names, need slice stuff for that)
* Is subdomain, is glue helper functions for this kind of stuff
* Make QuerySimple even simpler??
* Think about who closes who d.Close() and where
* Cleanups

Issues:
* FunkenSturm is kaput.
* Check closing of sockets d.Close()
* Check the network order, it works now, but this is on Intel??
* Make the testsuite work with public DNS servers
* pack/Unpack smaller. EDNS 'n stuff can be folded in
* Compression. Take stuff from Jan Mercl

Examples:
* Test impl of nameserver, with a small zone, 1 KSK and online  signing
