  This contains a number of things:

  1) Improve the documentation of the SSL module, with a fuller
     explanation of certificate usage, another reference, proper
     formatting of this and that.

  2) Fix Windows bug in ssl.py, and general bug in sslsocket.close().
     Remove some unused code from ssl.py.  Allow accept() to be called on
     sslsocket sockets.

  3) Use try-except-else in import of ssl in socket.py.  Deprecate use of
     socket.ssl().

  4) Remove use of socket.ssl() in every library module, except for
     test_socket_ssl.py and test_ssl.py.

  Somewhat-preliminary slice-object and extended slicing support for ctypes.
  The exact behaviour of omitted and negative indices for the Pointer type may
  need a closer look (especially as it's subtly different from simple slices)
  but there's time yet before 2.6, and not enough before 3.0a1 :-)
