Well, this breaks API.

Please rename old options, say:

  IPV6_PKTINFO => IPV6_2292PKTINFO
  IPV6_HOPLIMIT => IPV6_2292HOPLIMI
  IPV6_RTHDR => IPV6_2292RTHDR
  IPV6_DSTOPTS => IPV6_2292DSTOPTS

And, add allocate new values for 2292bis options like:

#define IPV6_RECVPKTINFO               48      /* RFC2292bis */
#define IPV6_PKTINFO                   49      /* RFC2292bis */
#define IPV6_RECVHOPLIMIT              50      /* RFC2292bis */
#define IPV6_HOPLIMIT                  51      /* RFC2292bis */
#define IPV6_RECVRTHDR                 52      /* RFC2292bis */
#define IPV6_RTHDR                     53      /* RFC2292bis */
#define IPV6_RECVHOPOPTS               54      /* RFC2292bis */
#define IPV6_HOPOPTS                   55      /* RFC2292bis */
#define IPV6_RECVDSTOPTS               56      /* RFC2292bis */
#define IPV6_DSTOPTS                   57      /* RFC2292bis */
#define IPV6_RECVRTHDRDSTOPTS          58      /* RFC2292bis */
#define IPV6_RTHDRDSTOPTS              59      /* RFC2292bis */

(This is what KAME people did, and I believe that it is the best way to keep
backward compatibility.)
