----------------------------------------+-----------------------------------
 DNS serials wrap around 2^32, with the previous 2^31 values being "before"
 and the next 2^31 being "after". The serial calculation code needs to
 handle this properly when comparing two serials to determine which one is
 >= the other, and also when incrementing it.

 The "unixtime" serial just needs to be calculated MOD 2^32, and
 "datecounter" requires no change.
