- New removal of obsolete RRSIGs
- Adding RRSIGs with RRSet to changeset
- Signature shallow copy rewritten
- Bad assumptions about RRSet count in node rewritten

- Not complete: Empty non-terminal's RRSIGs are deleted, but NSEC3 are created. (already fixed in 'master' branch, will fix during merge)
- Fails nsec->nsec3 transition test

- TTLs might get mixed up if we added RRSIG just as any other record

- Structures need to be renamed a bit, missing doxygen
- Optimization pending, but that's okay, since future zone API should take care of those

- RRSIGs from node are added to rrinfo section.
- When putting RRSIGs for each section, proper RRSIGs for each RRSet are syntesized and later freed.

- Added new public alloc helper functions to mempattern.h.
- RRSet owners are not allocated using memctx, because they might be dropped later and because DNAME has no memctx API.
- Only packet had its own memctx at the time of writing. Later, most RRSet operations should use custom allocators, for now, no allocator is used.

Dnstests Valgrind Check

Extra 32B is allowed for reachable, as dlopen() may cause this,
but it shouldn't be treated as an error.
