dns/TODO

Guidelines for the API:
o symmetrical, client side should be mirrored in the server
o clean, small API
o api-use should be self documenting
o zone structure -- only as rb-tree 
o fast data structures (rb-tree, when they come available)

o build simple: just query function, built on the cool stuff
o Key2DS, also for offline keys -- need to parse them ofcourse

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??

Issues:
* FunkenSturm is kaput.
* 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
* Config from /etc/resolv.conf
* d.Dial() and redialing those that work

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