 This is a subtask of #802. It should add the ability to keep bunch of unix
 domain sockets for sending the sockets from socket creator to components.

 It should consist of these parts:
  * A listening unix-domain socket is created somewhere in filesystem. The
 name is stored in self._socket_path (as other parts will need the path,
 and we want to be able to choose the path randomly in future).
  * When anything connects to the listening socket, it is accepted and
 kept.
  * When a line comes over one of the kept sockets, the newline is stripped
 and socket_request_handler is called with this string and the socket it
 came from.
  * When the remote closes one of the kept sockets, socket_consumer_dead is
 called.

 These functions are introduced in trac802 in boss (as stubs). They form
 interface to the other subtasks.
