The IPC pipes are now file objects, not file descriptors:
* mandos (ClientDBus.CheckedOK): Reorder to group methods, signals and
                                 properties together.
  (ClientHandler.handle,
  ForkingMixInWithPipes.process_request,
  ForkingMixInWithPipes.add_pipe_fds,
  MandosServer.add_pipe_fds): IPC pipes are now file objects, not FDs.
  (MandosServer.handle_ipc): - '' -  Take additional argument "sender"
                             containing the client IPC file object;
                             all callers changed.
