TODO

Must of the stuff is working, but there is a list of smaller things that need to be fixed.

Parsing
Speed, we can always go faster. A simple reflect server now hits 30/40K qps
Add handy zone data structure (r/b tree)? Or not...
Use the Exchange structure to deal with errors when resolving, esp. Timeout
IsSubdomain, IsGlue helper functions;
SaltLength in NSEC3 is ugly to set, should be automatically done. There are prolly a few more settings just like that -- need to look at them. -edns NSID is another
Add tsig check in 'q'?
Unknown RR parsing
\DDD in zonefiles
