Primarly fix the trace code. This was broken during the modfictions of the
DDNS code to use the bind libraries. This patch fixes that breakage and
includes support for the new DDNS code. This patch also deletes some dead
code and neatens up some log messages.

- An optimization described in the failover protocol draft is now included,
which permits a DHCP server operating in communications-interrupted state
to 'rewind' a lease to the state most recently transmitted to its peer,
greatly increasing a server's endurance in communications-interrupted.
This is supported using a new 'rewind state' record on the dhcpd.leases
entry for each lease. [ISC-Bugs #19601]

over-riding vlaues were not present in a matching fixed-address6 host
