  Implement UDP control block support.

  Add udpcb support with own fields and flags for UDP instead
  of further sticking things into in_pcb and flags fields.
  Attach the udpcb to the inp_ppcb in the kernel.

  Note: the udp tunneling parts are not (yet) existing in 7
  and thus were not merged.
