Changes done, although with far too many commits on account of finger trouble and git knowing best. I may be wrong, but what Travis and Appveyor caught seem to be not my problem. |

DOH: provision for using additional dedicated DOH probe slots
The function Curl_doh() uses two dedicated “probe slots” for holding
DOH query state independently for each of the DNS QTYPEs, A and AAAA.
In some use cases, additional host attributes, also available from the DNS,
are needed as connection parameters.
This PR simplifies coding for build-time allocation and run-time
management of extra probe slots which may be needed to hold
query state when retrieving such additional host attributes.
Relates to this posting to the curl-library mailing list.
