Closes #725 @35m

Commit refs #583.

Changed parameter checks in dnslib_rrset_merge. Now calls dnslib_dname_compare instead of just comparing pointers.

- Added zones.c/h to Knot.files (again, there is some problem with
  the repo probably).
- Added some debug output.
- Removed zone database from server completely - allocation,
  initialization and destroying is done in the nameserver only.

Chaned parameter checking in dnslib_rrset_merge. Calls dnslib_dname_compare if owner's dnames are not the same.
