DHCP Implementation is too minimal

[PherricOxide]

Honeyd's DHCP currently ignores the lease time (and a bunch of other DHCP params...), which means after the lease expires it'll keep hanging on to the IP even though it'll likely be assigned to someone else as well.

Things to do

Parse lease time and any other useful stuff out of DHCP ack packets
Attempt to renew address if the lease time is coming up soon (1/2 lease time is standard for a renew attempt)
Try and release/lease if the renew fails

Basically, implement all the lease parts of the protocol that are currently being ignored.

This was mostly fixed, but never closed. Honeyd attempts to renew the addresses now.
