This adds CONFIG_IP_NF_CT_PROTO_SCTP:
Connection tracking support for SCTP.  Using this, you can track
SCTP connections.  You have to load the following modules
for connection tracking:
	ip_conntrack_proto_sctp

Note that this code currently has limitations
- Multi homing is not supported.
- Cookie Echo Chunk handling for an existing connection not handled (Sec 5.2.4 - RFC 2960).
