Update x11vnc to 0.9.8.

New in the 0.9.8 x11vnc release:

        Better reliability for the Java Viewer applet when connecting
                through a Web Proxy via HTTPS.  A proxy hostname
                and port can be specified via applet parameters.
                Proxy Authentication via Auth-Basic is supported.
                More x11vnc printout in -ssl is provided to help
                troubleshoot this mode and other ssl connections.

        Stability improvements to -threads mode. Running x11vnc this
                way is more reliable now. Threaded operation sometimes
                gives better interactive response and faster updates. The
                threaded mode now supports multiple VNC viewers using
                the same VNC encoding (some only on Linux or enabled
                at build time.)  The threaded mode can also yield
                a performance enhancement in the many client case
                (e.g. class-room broadcast.) We have tested with 30 to
                50 simultaneous clients.  See also -reflect.

  miscellaneous new features and changes:

        x11vnc automatically tries to work around an Xorg server bug
                involving infinitely repeating keys when turning off key
                repeating. Use -repeat if the automatic workaround fails.
                Also, the environment variable X11VNC_IDLE_TIMEOUT
                (seconds) is provided.

        In -reflect mode the environment variable X11VNC_REFLECT_PASSWORD
                is provided.

        The -clip mode works under -rawfb.

        The -nounixpw option can disable unixpw mode if an earlier option
                enables it (e.g. -svc).

        Scroll detection is skipped for windows with 'OpenOffice' in
                their name.
