- Fixed check in RDATA adjusting.
- Fixed searching for wildcard covering RDATA dname.
- Fixed zone_contents_find_dname().

TODO: Leaks memory from some nodes created during load, but only
      when there are some RDATA dnames covered by a wildcard in
      the zone.

TODO: Use the new functions in all possible cases, there are more
      possible, mostly where ns_error_response() is now used.

This code was disabled long ago in a temporary commit dealing with
something totally different (f97bde66). Reenabled it, but I'm not
sure this won't break something else.

Also replaced the closest encloser being saved to the RDATA dname
by the wildcard child. It should prevent possible problems with
query processing. Although it is worth checking out if they are not
accustomed to this (closest encloser in the dname.node field).

- Now should be finally correct. If there is less or more data
  than expected, the packet is treated as malformed.

- If there is no such RRSet in the node, do not try to copy it.

- Changed check to decide whether to parse rest or not.
  Hopefully this does not break other cases.

- Not finished yet!
