  Modified files:
    sys/kern             uipc_socket.c 
  Log:
  Add additional annotations to soreceive(), documenting the effects of
  locking on 'nextrecord' and concerns regarding potentially inconsistent
  or stale use of socket buffer or stack fields if they aren't carefully
  synchronized whenever the socket buffer mutex is released.  Document
  that the high-level sblock() prevents races against other readers on
  the socket.
  
  Also document the 'type' logic as to how soreceive() guarantees that
  it will only return one of normal data or inline out-of-band data.
