suggested NOTIFY logging improvement (with patch for 8.2.2-P5)

[Scott Bertilson]

  We are running QIP and allowing it to do dynamic DNS updates
when administrators make changes (not using it with DHCP at
this time).  We have been having some problems with serial
number synchronization.  In the process of debugging it,
it seemed helpful to modify the "Sent NOTIFY" log message
to include the zone serial number.  It is a very simple
change (hope this is also true in BIND 9), so hope it
can be included.
