[SCTP]: Beginning of sin_port fixes.

Browse Source 
That's going to be a long series.  Introduced temporary helpers
doing copy-and-convert for sctp_addr; they are used to kill
flip-in-place in global data structures and will be used
to gradually push host-endian uses of sctp_addr out of existence.
