A NSEC record is need to deny any other name that might exist.
Also don't blindly perform the interface conversion when getting
glue for NS records as they now may include RRSIG - also add tests
for that.
Fix the delegation handling in the *file* and *dnssec* middleware.
Refactor tests a bit and show that they are failling.
Add a Tree printer, cleanups and tests.
Fix wildcard test - should get no answer from empty-non-terminal
Return a delegation when seeing one while traversing the tree in
search of an answer.
Put the SOA and NS record in the zone.Apex as these are to be handled
somewhat special.
Lowercase record on insert to make compares easier. This lowercases
all RR that have domain names in their rdata as well.
Drop the use of dns.RR when in fact the only thing we use is the name
and type of the RR. Cleans up a bunch of stuff and also stops the weird
making of dns.RRs just for a lookup. Should safe some memory as well.
Fixes: #66
When looking for a name in tree, return wether we got to a longer one -
if so we had an ent. Add tests + dnssec tests and refactor the tests as
well a bit.
Reply to queries when you have a wildcard in the zone. This works
for DNS and DNSSEC. Thing missing is NODATA responses for that specific
wildcard.
Add wildcard_test.go as well.
