MFC r272886:

  Add context pointer and source address to the UDP tunnel callback

  These are needed for the forthcoming vxlan implementation. The context
  pointer means we do not have to use a spare pointer field in the inpcb,
  and the source address is required to populate vxlan's forwarding table.
