Delegation Point.
For a domain name, the NS rrset, and the A and AAAA records for those.
| struct delegpt_addr* delegpt::usable_list |
the list of usable targets; subset of target_list the items in this list are not part of the result list.

| int delegpt::bogus |
if true, the NS RRset was bogus.
All info is bad.

| uint8_t delegpt::has_parent_side_NS |
if true, the parent-side NS record has been applied: its names have been added and their addresses can follow later.
Also true if the delegationpoint was created from a delegation message and thus contains the parent-side-info already.

| uint8_t delegpt::fallback_to_parent_side_NS |
if true, the delegation point has reached last resort processing and the parent side information has been possibly added to the delegation point.
For now this signals that further target lookups will ignore the configured target-fetch-policy and only resolve on demand to try and avoid triggering limits at this stage (.i.e, it is very likely that the A/AAAA queries for the newly added name servers will not yield new IP addresses and trigger NXNS countermeasures.
