    mDNS: probe rate limiting if more then 15 conflicts occur in 10s
    According to RFC6762 section 8.1:
    If fifteen conflicts occur within any ten-second period, then the
    host MUST wait at least five seconds before each successive
    additional probe attempt.
    If the host restarts mDNS, instead of a probe wait timeout randomly
    chosen between 0 and 250ms, we wait 5s if more then 15 conflicts
    occured in 10seconds. This flag is reset from the moment probing

    mDNS: probe tiebreaking added
    mDNS: first version probe tiebreaking added
    This first version works for our MCU boards but does only compare
    the first question and answer. It does not sort the list of answers
    and it does not search for answers or questions.
    mDNS: improved probe question handling
    For every probe question in our packet, we check the presence
    in the incomming packet until we find a match. then we perform
    the tiebreaking. At the moment we still only look at the first
    mDNS: evaluate all answers in the authoritative section
    The authoritative sections of both messages are evaluated.
    The records that answer the probe question are sorted in to lists.
    Then the lists are compared pairwise. A winner and a loser are
    chosen and the host reacts on the outcome (ignore or stop probing).
    mDNS: add support for name decompression in rdata when comparing.
    For probe tiebreaking we need to compare RR's. It is possible that
    the rdata of an RR contains compessed names (SRV record). We need
    to decompress it first before we do the comparison.
