* sockopt.h: Add SOPT_SIZE_CMSG_PKTINFO{_IPV{4,6}} define, for
sizeof pktinfo as appropriate, to be used when allocating msg
buffers. export setsockopt_pktinfo() and
getsockopt_pktinfo_ifindex()
* sockopt.c: (setsockopt_pktinfo_ifindex) new function to portably
set received ifindex sock option.
(getsockopt_pktinfo_ifindex) portably retrieve ifindex.
(getsockopt_cmsg_data) retrieve indicated control info from
message header.
(getsockopt_ipv6_pktinfo_ifindex) ipv6 version of above.
(setsockopt_ipv4_pktinfo) v4 version
(setsockopt_pktinfo) the exported version
(getsockopt_ipv4_pktinfo_ifindex) v4 specific version
(getsockopt_pktinfo_ifindex) the exported version
