TODO

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

go test; only works correct on my machine
Add handy zone data structure (r/b tree)? Or not...
Use the Exchange structure to deal with errors when resolving, esp. Timeout
Add tsig check in 'q'?
Tsig is handled in the library, api for querying tsig status
Query source address?
NSECx bitmap length array of 256 block lens set to 0. scan RRs, save highest RR / 8 in each block. len is 2 * # non-0 blocks + sum block len
