If a negative response has an SOA in the authority section, then
zone_for_name() will now use it to make the search more efficient.

zone_for_name() now has an optional lifetime parameter which limits the
total time that can be spent resolving.

avoid compatibility warnings for python 3.12

The APLItem constructor should make sure that the address field
is not too long for unknown address families.  [#672]

Do some basic xfr checks with an unversioned zone too.
