Add selftests for kernel behavior with regard to various classes of unallocated/reserved IPv4 addresses, checking whether or not these addresses can be assigned as unicast addresses on links and used in routing. Expect the current kernel behavior at the time of this patch. That is: * 0/8 and 240/4 may be used as unicast, with the exceptions of 0.0.0.0 and 255.255.255.255; * the lowest address in a subnet may only be used as a broadcast address; * 127/8 may not be used as unicast (the route_localnet option, which is disabled by default, still leaves it treated slightly specially); * 224/4 may not be used as unicast.
