- Tack parameter request list on to lease state structure so that it will

still be available when we call cons_options.
- Pass parameter request list to cons_options where needed, and in any case
pass the extra argument.
- Free parameter request list before freeing lease state structures.

- Pull up recent 2.0 changes.
...
- Fix some problems in DHCPREQUEST code regarding client identity.
- Update references to lease's shared network to use subnet pointer.
- If there's more than one lease matching a particular hardware address,
examine them all for possible applicability in find_lease().
- Only recover abandoned leases on DHCPREQUEST if the request was for
the specific abandoned lease. Push all other abandoned lease
recovery code out into DHCPDISCOVER/allocate_lease processing.

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.
