Bugfix: when matching RR entries, sometimes the name and type are not sufficiently unique.
...
- Added rr_entry_match() to search for an exact RR entry. For most RRs,
matching its name is sufficient but for PTRs, its target needs to be
matched as well.
- Rewrote populate_answers() logic to make sure all matching RRs (by
name and type) are added.
- When responding, populate our answers first, then check them against
the Known-Answer list.
