- IPSECKEY rdata were being parsed in wrong way - two items were stored in one. This caused no problems during responding.
- Changed storing of APL rdata so that it is the same as TXT, currently, it might have caused undesired behaviour with transfered rdata or with rdata loaded from binary.

Closes #2002 @3h

Updated log messages for denied outgoing transfers.

fixes #2007 @3h

- Reorganized groups.
- Updated main page.

refs #1996 @30m

- If node was empty no action was taken, but all RRs from node in the other tree
  have to be added to ADD section of changeset in such a case.
- Renamed and moved functions for clarity.

Divided into two parts. In first part the 'prev' pointers are
set. The second does the rest of the work. It's necessary because
the 'prev' pointers are used in search for domain names in RDATA
and may not be yet set well. This caused some rare problems.

This allows to clear any existing requests in the queue,
preventing potential memory leaks on shutdown.

- If a node contains a CNAME RRSet or just a RRSIG covering a
  CNAME, the server will not try to resolve the CNAE chain.

This option allows binding to the same port using separate
IPv6 and IPv4 socket.
