    Authenticates an XmlStream against a Jabber server as a Client.

    This only implements non-SASL authentication, per
    U{JEP-0078<http://www.jabber.org/jeps/jep-0078.html>}. Additionally, this
    authenticator provides the ability to perform inline registration, per
    U{JEP-0077<http://www.jabber.org/jeps/jep-0077.html>}.

    Under normal circumstances, the BasicAuthenticator generates the
    L{xmlstream.STREAM_AUTHD_EVENT} once the stream has authenticated. However,
    it can also generate other events, such as:
      - L{INVALID_USER_EVENT} : Authentication failed, due to invalid username
      - L{AUTH_FAILED_EVENT} : Authentication failed, due to invalid password
      - L{REGISTER_FAILED_EVENT} : Registration failed

    If authentication fails for any reason, you can attempt to register by
    calling the L{registerAccount} method. If the registration succeeds, a
    L{xmlstream.STREAM_AUTHD_EVENT} will be fired. Otherwise, one of the above
    errors will be generated (again).


    @cvar INVALID_USER_EVENT: See L{IQAuthInitializer.INVALID_USER_EVENT}.
    @type INVALID_USER_EVENT: L{str}

    @cvar AUTH_FAILED_EVENT: See L{IQAuthInitializer.AUTH_FAILED_EVENT}.
    @type AUTH_FAILED_EVENT: L{str}

    @cvar REGISTER_FAILED_EVENT: Token to signal that registration failed.
    @type REGISTER_FAILED_EVENT: L{str}

    This returns a L{xmlstream.XmlStreamFactory} with an L{XMPPAuthenticator}

    Initializes an XmlStream connecting to an XMPP server as a Client.

    This authenticator performs the initialization steps needed to start
    exchanging XML stanzas with an XMPP server as an XMPP client. It checks if
    the server advertises XML stream version 1.0, negotiates TLS (when
    available), performs SASL authentication, binds a resource and establishes
    a session.

    Upon successful stream initialization, the L{xmlstream.STREAM_AUTHD_EVENT}
    event will be dispatched through the XML stream object. Otherwise, the
    L{xmlstream.INIT_FAILED_EVENT} event will be dispatched with a failure
    object.

    After inspection of the failure, initialization can then be restarted by
    calling L{ConnectAuthenticator.initializeStream}. For example, in case of
    authentication failure, a user may be given the opportunity to input the
    correct password.  By setting the L{password} instance variable and restarting
    initialization, the stream authentication step is then retried, and subsequent
    steps are performed if successful.

    @ivar jid: Jabber ID to authenticate with. This may contain a resource
               part, as a suggestion to the server for resource binding. A
               server may override this, though. If the resource part is left
               off, the server will generate a unique resource identifier.
               The server will always return the full Jabber ID in the
               resource binding step, and this is stored in this instance
               variable.
    @type jid: L{jid.JID}
