dcc557db27 - Some time value size fixes in 3.0.4 brought on from FreeBSD /usr/ports were 
misapplied to server values rather than client values.  The server no longer
  advertises 8-byte lease-time options when on 64-bit platforms.

25b988c68f - The IO system now tracks all local IP addresses, so that the DHCP 
applications (particularly the dhcrelay) can discern between what frames
  were tranmsitted to it, and what frames are being carried through it which
  it should not intercept. [ISC-Bugs #15573]

15c24b882b Changed supersede_lease() to return 1, even if the commit option is 
not specified.  (Before, it would always return 0 if commit was not
given.)  Fixed up the one call to supersede_lease() which expected
the old behavior.

Added a check to supersede_lease() to return an error if the pimmediate
flag is given, and commit is not.  (You should never be sending information
on an uncommitted lease to a peer.)

Separated the failover queue update (the propogate flag) test from
the commit test in supersede_lease(), so that you can now enqueue an
update on an uncommitted lease.

b992d7e23d DDNS implementation rewrite. DDNS should now operate according to 
<draft-ietf-dhc-dhcp-dns-12.txt>.

common/options.c, common/tables.c, includes/dhcp.h:
  Split the fqdn.name option into fqdn.hostname and fqdn.domainname.

includes/dhcpd.h, server/Makefile.dist, server/ddns.c, server/dhcp.c,
server/mdb.c, server/stables.c:
  Added a new file (server/ddns.c) containing the DDNS updates code.
  This file exports two functions: ddns_updates() and ddns_removals().
  ddns_updates() is called when a lease is granted, and ddns_removals()
  is called when the lease expires or is released.

server/dhcpd.c:
  Remove the previous DDNS update code, and add default code for the
  ddns-hostname, ddns-domainname, ddns-ttl, and ddns-rev-domainname
  server options.
