  1. upstream: DoT: Add proper handling of out-of-order responses 

    When processing multiple queries through a single DoT upstream, we might get
a DNS ID mismatch if responses are received out of order (cf. PR AdguardTeam#269).

We fix this by storing all responses with unknown IDs in a map from
which they can be retrieved later on.

  2. upstream: DoT: Match QNAME, QCLASS, and QTYPE fields from response to… 

    … query

In order to deal with response reordering, RFC 7766 [1] requires that we
match the QNAME, QCLASS, and QTYPE fields in the response to the query.
