478028e7ec - Fix the DDNS update code to correctly send a client FQDN option, to not 
do the update if it seems unnecessary, and to handle client updates if
  configured to do so.

bdad826feb - Don't save the IP address as an ASCII string variable.Don't update 
the PTR if the update of the A failed.
- Don't do the delete with the 'interim/rfc' code if we didn't do the
  add with the 'interim/rfc' code.
- Don't delete the dhcid RR if there is still a valid A RR, and don't
  just delete all A RRs when installing a new one - the client may
  legitimately have IP addresses on more than one subnet.

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.
