* sockopt.c (getsockopt_ipv4_ifindex): Document calling convention. Beef up comments. Handle the case where the cmsghdr has a zero controllen, or more specifically when the wanted option is not present. This is needed for Solaris 8, and in general for any platform for which configure finds a method and it can fail. Mark some changes with XXX to be cleaned up post 0.98.
