Switch buffer -> client connection to client -> buffer

We now connect to buffers from the client, instead of connecting
buffers to the client. This has the following advantages:

* Simplifies the client event loop.
* Makes the client a real client (no more serversocket dependency).
* Slightly more secure, as we no longer have to trust buffers not
  lying about their process ids.
* Facilitates the potential future addition of connections from
  several clients to a single buffer.
