- plug memory leak.
- fixed a length of the sadb extension in the case of pfkey_send_x5(). - used getprotobynumber() for printing a upper layer protocol name. - modified the output format against the change of the setkey syntax about a icmp6 type/code. - don't enumerate reserved fields. use memset. Obtained from: KAME
