"AAAA response" is ambiguous

[ericorth]

In the context of this draft "AAAA response" seems it could be interpreted as just the DNS response to the AAAA query. But for most of the usage/discussion, I think we want AAAA records received in response to the AAAA query or AAAA records received in the Additional section of the response to the HTTPS query, whichever is received first.

Maybe we should rephrase all those references to "received AAAA records" or something like that. Maybe we even need an explicit mention that those records could come in the response to the HTTPS query and that clients should use those if received first instead of waiting for a response to the AAAA query.
