Bill Paul b1d8279802 Hm... wonder how long this has been here. 
The logic in get_myaddress() is broken: it always returns the loopback
address due to the following rule:

                if ((ifreq.ifr_flags & IFF_UP) &&
                    ifr->ifr_addr.sa_family == AF_INET &&
                    (loopback == 1 && (ifreq.ifr_flags & IFF_LOOPBACK))) {

The idea is that we want to select the interface address only if it's
up and it's in the AF_INET family. If it turns uout we don't have
such an interface available, we make a second pass through the loop,
this time settling for the loopback interface. But the logic inadvertently
locks out all cases when loopback == 0, so nothing is ever selected until
the second pass (when loopback == 1).

This is changed to:

                if (((ifreq.ifr_flags & IFF_UP) &&
                    ifr->ifr_addr.sa_family == AF_INET) ||
                    (loopback == 1 && (ifreq.ifr_flags & IFF_LOOPBACK))) {

which I think does the right thing.

This is yet another bogon I discovered during NIS+ testing; I need
get_myaddress() to work correctly so that the callback code in the
client library will work.
