Almost complete by now, only dhclient-script.hurd and
dhclient-script.hurd.udeb remains to finalize. The tests in common/tests
passes. When run-testing a new problem came up, see below.

Almost ready for review.

When trying to run the client, the interface scan fails. In face the
function getifaddrs returns a non-zero value. The same problem can
easily be tested with the code given at the manpage for getifaddrs.
Below is a stripped down version of that code: Why does it fail?

/* File: fails_on_hurd.c */

      #include <arpa/inet.h>
       #include <sys/socket.h>
       #include <netdb.h>
       #include <ifaddrs.h>
       #include <stdio.h>
       #include <stdlib.h>
       #include <unistd.h>

       int
       main(int argc, char *argv[])
       {
           struct ifaddrs *ifaddr, *ifa;
           int family, s;
           char host[NI_MAXHOST];

           if (getifaddrs(&ifaddr) == -1) {
               perror("getifaddrs");
               exit(EXIT_FAILURE);
          }
}

gcc -g fails_on_hurd.c
