This introduces basic mptcp sockets diag support.
As IPPROTO_MPTCP excedes 8 bits, we need some changes at the inet_diag level:
a new attribute is introduced to allow user-space providing u32 protocol
values.

Patch 2 introduces new token APIs to allow traversing the existing msks, while
patch 3 bring in the actual diag implementation.

Paolo Abeni (3):
  inet_diag: support for wider protocol numbers
  mptcp: add msk interations helpers
  mptcp: add MPTCP socket diag interface
