[SCTP]: Implement the Supported Extensions Parameter
SCTP Supported Extenions parameter is specified in Section 4.2.7
of the ADD-IP draft (soon to be RFC). The parameter is
encoded as:
0 1 2 3
0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

It contains a list of chunks that a particular SCTP extension
uses. Current extensions supported are Partial Reliability
(FWD-TSN) and ADD-IP (ASCONF and ASCONF-ACK).
When implementing new extensions (AUTH, PKT-DROP, etc..), new
chunks need to be added to this parameter. Parameter processing
would be modified to negotiate support for these new features.
