[SCTP] More typedef removals. 

Continue typedef removal.  Also, change sctp_chunk.num_times_sent
counter to a resent flag.  There was a rather obscure, unlikely,
and in the end fairly benign bug sitting there if num_times_sent 
wrapped.  However, there's no need to keep this counter, as its
use was really just to know if we'd ever resent this chunk.
