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 not be used as unicast.

ip: Treat IPv4 segment's lowest address as unicast
selftests: Lowest IPv4 address in a subnet is valid
net/ipv4/fib_frontend.c
Expect the lowest IPv4 address in a subnet to be assignable
and addressable as a unicast (non-broadcast) address on a
local network segment.
