added. If this option is enabled, dhcpd will perform normal DHCID
conflict resolution (the default). If this option is disabled, it will
instead trust the assigned name implicitly (removing any other bindings

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.

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.
