Bring in some kernel bootp support. This removes the need for netboot
to fill in the nfs_diskless structure, at the cost of some kernel bloat. The advantage is that this code works on a wider range of network adapters than netboot. Several new kernel options are documented in LINT. Obtained from: parts of the code comes from NetBSD.
