  Log:
  Lock down rawcb_list, a global list of control blocks for raw sockets,
  using rawcb_mtx.  Hold this mutex while modifying or iterating over
  the control list; this means that the mutex is held over calls into
  socket delivery code, which no longer causes a lock order reversal as
  the routing socket code uses a netisr to avoid recursing socket ->
  routing -> socket.
  
  Note: Locking of IPsec consumers of rawcb_list is not included in this
  commit.
