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.

77956158d4 - Make option spaces stored as linked lists first-class objects. 
- Use these spaces for the agent option space, fqdn option space and
  nwip option space.
- Make encapsulator and decoder for fqdn option space.
- Support the agent option space the way all option spaces are supported
  to the extent possibol, rather than special-casing it.
- Add an enumerator function for defined options in an option space.
- Support encapsulated options directly with a format string, rather than
  as another special case.

4038ec529e - Regularize expression evaluation calls so that they are all passed a pointer 
to the incoming packet, if any, the current lease, if any, the parsed
  incoming options, and the in-scope configuration file options.
- Incoming packets are now reference counted, so that the callee can save
  them for later expression evaluation (e.g., in dhcp_reply).
