Should enable _BSD_SOURCE, _SVID_SOURCE, _ATFILE_SOURCE,
_LARGEFILE64_SOURCE, _ISOC99_SOURCE, _XOPEN_SOURCE_EXTENDED,
_POSIX_SOURCE, _POSIX_C_SOURCE, and _XOPEN_SOURCE.

We already require features exposed by some of these defines. Lets
enable them globally to avoid problems caused by the ordering of
includes.

- Discovered because empty RRSet conversion was added
- Code was disabled for some (imho wrong) reason

- Adding such RRSIG did not work - no way to differentiate between empty and non-existent records.

Change-Id: I7d6089497cbcee4c26c1f3c3e7059d8b1ff3ffe0

- Added private function that creates a node and an RRSet for given RRSIG and inserts everything in the zone.
- Orphan RRSIG is no longer an error.

- Enabled saving of empty RRs - only header and 0 RDLENGTH are saved if there are no RDATA in RRSet
- Moved code saving header to wire to an extra function.
