add SIOCGIFDATA ioctl 

For interfaces that do not support SIOCGIFMEDIA (for which there are
quite a few) the only fallback is to query the interface for
if_data->ifi_link_state.  While it's possible to get at if_data for an
interface via getifaddrs(3) or sysctl, both are heavy weight mechanisms.

SIOCGIFDATA is a simple ioctl to retrieve this fast with very little
resource use in comparison.  This implementation mirrors that of other
similar ioctls in FreeBSD.
