At sockets layer we touch only per-socket data, which is solock()
protected().
At protocol layer, unix(4) and key management sockets have no
(*pr_ctloutput)() handlers. route_ctloutput() touches only per socket
data, which is solock() protected. inet{,6} globals are protected by
netlock, which is solock() backend for corresponding sockets.
