Fixes from Kazushi Sugyo:

	1) print the payload length in AH headers correctly (the field's
	   value is length of the payload, minus 2, divided by 2, so we
	   have to add 2 before multiplying by 2);

	2) correctly handle, in an SIOCGIFCONF list, entries whose
	   address has an "sa_len" field less than the size of a "struct
	   sockaddr" (the length of the address in an entry is the
	   maximum of the real length and the size of a "struct
	   sockaddr").
