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]
best interpretation of it. The only thing confusing me is that I thought
he'd fixed all the byte order dependencies in an elegant way, but I
still see some rather ugly #ifdefs in this code. Oh well. At least it
works on minbar.
immediately responded to, but are placed on a queue (attached to
the dhcp_failover_state_t structure). Updated leases are committed
only when the queue is drained, giving a significant performance
increase.
The toack queue is drained:
a) when the queue size exceeds half the partner's max-unacked-updates
setting, or
b) two seconds after the last update message is received.
Added 'refcnt' and 'next' fields to the failover_message_t structure,
to allow messages to be placed on the toack queue.
On the sending side, leases are no longer committed immediately after
being acked. Rather, the commit is deferred until no further acks are
pending. This also gives a major gain in performance.

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.
