This adds proper handling of the ciaddr field as well as the "Requested IP Address" option to slirp's DHCP server. If the client requests an invalid or used IP, a NAK reply is sent, if it requests a specific but valid IP, this is now respected. NAK'ing invalid IPs is specifically useful when changing the slirp IP range via '-net user,ip=...' while the client saved its previously used address and tries to reacquire it. Now this will be NAK'ed and the client will start a new discovery round.
