Due to the documented bug in inet_aton(3), it wasn't possible

Browse Source 
to use 0xffffffff (INADDR_NONE) as a netmask value.  The fix
is to use inet_addr(3) which doesn't suffer from this problem.

PR:		bin/28873

Also, while here, fixed the bug when netmask value was ignored
(RTF_HOST flag was set) if the "destination gateway netmask"
syntax is used, e.g. ``route add 1.2.3.4 127.1 255.255.255.255''.
