  MFC r212155:

      In protosw we define pr_protocol as short, while on the wire
      it is an uint8_t.  That way we can have "internal" protocols
      like DIVERT, SEND or gaps for modules (PROTO_SPACER).
      Switch ipproto_{un,}register to accept a short protocol number(*)
      and do an upfront check for valid boundries. With this we
      also consistently report EPROTONOSUPPORT for out of bounds
      protocols, as we did for proto == 0.  This allows a caller
      to not error for this case, which is especially important
      if we want to automatically call these from domain handling.
  
      (*) the functions have been without any in-tree consumer
      since the initial introducation, so this is considered save.
  
      Implement ip6proto_{un,}register() similarly to their legacy IP
      counter parts to allow modules to hook up dynamically.
