Do client classification. If user supplies a dhcp-lease-time or related option, print a warning when issuing a lease.

Don't respond to requests that are newer than a configured number of seconds. Enforce a minimum lease time, if specified. If a dhcp-server-identifier option has been specified, use that instead of coming up with one from the shared_network structure. Allow the routers option to be set to the client's address. Be more clever about dealing with duplicate leases.

If we happen across an abandoned lease when trying to find a lease to allocate, try using the abandoned lease. If the client asks for a lease on one address, but we find another lease that's also assigned to it, make every effort to free the duplicate lease, since a client can't have two leases on the same network at the same time.

Move a ton of bits from the lease structure into the lease_state structure. The lease structure is permanent, whereas the state structure is ephemeral, which means that leases now consume less memory (memory consumption is now about the same as in Beta 5 Patchlevel 14). Allocate and free the lease_state structure. If ack_lease is called on a lease that already has a state structure, we're already acking something, so we don't try to ack it again.
