* sysdeps/mach/hurd/if_index.c: Redone to use new interfaces in the Hurd pfinet server, using equivalent code from the Linux version in sysdeps/unix/sysv/linux/if_index.c. In detail: Include <unistd.h>, <error.h>, <sys/ioctl.h>, <hurd/ioctl.h> and <hurd/pfinet.h>.  Don't include <sys/mman.h> and <hurd/fsys.h> anymore. (if_nametoindex): New implementation using SIOCGIFINDEX. (if_freenameindex): Straight copy of the Linux version. (if_nameindex): New implementation based on pfinet_siocgifconf and SIOCGIFINDEX. (if_indextoname): New implementation using SIOCGIFNAME. (map_interfaces): Function removed. From Marcus Brinkmann <marcus@gnu.org>.
