  Issue 2408: remove the _types module
  It was only used as a helper in types.py to access types (GetSetDescriptorType and MemberDescriptorType),
  when they can easily be obtained with python code.
  These expressions even work with Jython.

  I don't know what the future of the types module is; (cf. discussion in http://bugs.python.org/issue1605 )
  at least this change makes it simpler.

  - Issue #2550: The approach used by client/server code for obtaining ports
    to listen on in network-oriented tests has been refined in an effort to
    facilitate running multiple instances of the entire regression test suite
    in parallel without issue.  test_support.bind_port() has been fixed such
    that it will always return a unique port -- which wasn't always the case
    with the previous implementation, especially if socket options had been
    set that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT).  The
    new implementation of bind_port() will actually raise an exception if it
    is passed an AF_INET/SOCK_STREAM socket with either the SO_REUSEADDR or
    SO_REUSEPORT socket option set.  Furthermore, if available, bind_port()
    will set the SO_EXCLUSIVEADDRUSE option on the socket it's been passed.
    This currently only applies to Windows.  This option prevents any other
    sockets from binding to the host/port we've bound to, thus removing the
    possibility of the 'non-deterministic' behaviour, as Microsoft puts it,
    that occurs when a second SOCK_STREAM socket binds and accepts to a
    host/port that's already been bound by another socket.  The optional
    preferred port parameter to bind_port() has been removed.  Under no
    circumstances should tests be hard coding ports!

    test_support.find_unused_port() has also been introduced, which will pass
    a temporary socket object to bind_port() in order to obtain an unused port.
    The temporary socket object is then closed and deleted, and the port is
    returned.  This method should only be used for obtaining an unused port
    in order to pass to an external program (i.e. the -accept [port] argument
    to openssl's s_server mode) or as a parameter to a server-oriented class
    that doesn't give you direct access to the underlying socket used.

    Finally, test_support.HOST has been introduced, which should be used for
    the host argument of any relevant socket calls (i.e. bind and connect).

    The following tests were updated to following the new conventions:
      test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
      test_poplib, test_ftplib, test_telnetlib, test_socketserver,
      test_asynchat and test_socket_ssl.

    It is now possible for multiple instances of the regression test suite to
    run in parallel without issue.
