Named returns associated

* A/AAAA records with MX lookups if available
* A/AAAA records with SRV lookups if available
* SRV/A/AAAA records with NAPTR lookups if available
* A/AAAA records with NAPTR lookups if available

As of 9.11 named returns associated

* A/AAAA/TLSA records with MX lookups if available
* A/AAAA/TLSA records with SRV lookups if available
* SRV/A/AAAA/TLSA records with NAPTR lookups if available
* A/AAAA records with NAPTR lookups if available

Now for all of these the original lookup could be stalled for cache
misses and the related data fetched if the server is offering
recursive service to the clients.

It would also be possible when offering recursive service to perform
prefetching on cache misses.

It would also be possible to return A on AAAA and AAAA on A.

It's up to the client to accept or ignore the records.
