    DNS-over-QUIC: RFC implementation
    DoQ is now a standard and our implementation should be up-to-date now.
    The main issue is that we're not using a 2-byte prefix for DNS messages.
    This is resolved in this pull request. Note, that we still support the
    old clients that do not send any prefix.
