Getaddrinfo result for remote server is stored in net_t structure. This allows
to query each resolved address via net_t.srv. It is important for example if
the server has associated AAAA and A records, but listens on IPv4 address only.

General idea is regular search with keeping node stack.
If node is found, then return current node.
If node is htable, search for suffixes in htable.
If anything fails, walk up the visited nodes and check if
any visited node has value. If yes, then it is a prefix.

f.e. searching for 'abcd'
visited nodes: root -a-> {1:trie} -b-> {2:htable}
1. search htable for 'cd', 'c'
2. retrace to node {1}, does it have value?
3. yes, node1 is prefix 'ab' for 'abcd'

Previous with full dname copy and chopping was really inefficient.
Yields approx. 20% lower relative cost, 6% throughput increase.

every time when a new signature is needed.

Handler destructor was called only if handler was brought down
while the server was running. Also it didn't free the context struct.

Previously it was set to maximum size and msg_namelen was never
reset, which could cause problems with mixed IPv6/IPv4.

Fixed missing RCU unlock in early exit.
Expire event synchronized RCU before marking event as finished,
this could result in deadlocking threads holding RCU read lock while
waiting for event cancellation.
Transfer requests usually hold zone reference, so no RCU locking is
required.

- New parser does not report empty file as an error (and nor should it, I guess), so an extra check had to be added.

- It makes no sense to move compression offset for RDLENGTH bytes for each type, the value was totally wrong.
- It would work fine for single RRs, but if there were more than one, and if a comprimable DNAME appeared for the first time in the packet, later references to this DNAME would be broken.
