Subject: [Net/2] Simple patch to sbin/route/route.c for inet_aton()

The Net/2 route.c uses inet_addr() instead of inet_aton(). This makes
it impossible to specify an IP address of 255.255.255.255 to the route
program. This came up when I was trying to figure out how cloning
worked, and was wondering why
$ route change UVM-NET -cloning -genmask 255.255.255.255
wasn't working, but
$ route change UVM-NET -cloning -genmask 255.255.255.0
did indeed have the expected effect. This patch fixes this. (Now if
only the Net/2 TCP would take advantage of it...)
