DHCP Forwarder

This program forwards DHCP messages between subnets with different sublayer broadcast domains. It is similarly to the DHCP relay agent dhcrelay of ISC's DHCP, but has the following features which are important for me:

It tries to be RFC 2131/2132 and 3046 compliant. Probably it works with BOOTP (RFC 951) also, but since the handling of the giaddr field is described misleading (see RFC 1542), there may occur problems.
