This change adds constant IP_PKTINFO to GNAT.Sockets.Constants to support
obtaining additional, ancillary information about received IP datagrams on
systems that support this option.

Further changes are expected from Sam Tardieu on this PR, as per a
previous discussion between Thomas and Sam off-list.
