Currently MTU handling is spread over SCTP stack. There are multiple
places doing same/similar calculations and updating them is error prone
as one spot can easily be left out.
This patchset converges it into a more concise and consistent code. In
general, it moves MTU handling from functions with bigger objectives,
such as sctp_assoc_add_peer(), to specific functions.
It's also a preparation for the next patchset, which removes the
duplication between sctp_make_op_error_space and
sctp_make_op_error_fixed and relies on sctp_mtu_payload introduced here.
More details on each patch.
