Defines Cross Paths mode.

In comparison with Cross to Primary Paths Blocking, Cross Paths modes 1 and 2 have some differences:
- SCTP defines straight and cross paths differently.
- SCTP does not allow user requested HB to be sent through disabled cross path.
- SCTP disables "Use Cross Paths" when the number of IP paths exceeds 16.
