Log Message:
Update libVNCServer to 0.9.8.

0.9.8
   - Overall changes:
     * Automagically generated API documentation using doxygen.
     * Added support for pkg-config.
     * Fixed Mingw32 cross compilation.
     * Fixed CMake build system.

   - LibVNCServer/LibVNCClient:
     * All files used by _both_ LibVNCServer and LibVNCClient were put into
       a 'common' directory, reducing code duplication.
     * Implemented xvp VNC extension.
     * Updated minilzo library used for Ultra encoding to ver 2.04.
       According to the minilzo README, this brings a significant
       speedup on 64-bit architechtures.

   - LibVNCServer:
     * Thread safety for ZRLE, Zlib, Tight, RRE, CoRRE and Ultra encodings.
       This makes all VNC encodings safe to use with a multithreaded server.
     * A DisplayFinishedHook for LibVNCServer. If set, this hook gets called
       just before rfbSendFrameBufferUpdate() returns.
     * Fix for tight security type for RFB 3.8 in TightVNC file transfer
       (Debian Bug #517422).

   - LibVNCClient:
     * Unix sockets support.
     * Anonymous TLS security type support.
     * VeNCrypt security type support.
     * MSLogon security type support.
     * ARD (Apple Remote Desktop) security type support.
     * UltraVNC Repeater support.
     * A new FinishedFrameBufferUpdate callback that is invoked after each
       complete framebuffer update.
     * A new non-forking listen (reverse VNC) function that works under
       Windows.
     * IPv6 support. LibVNCClient is now able to connect to IPv6 VNC servers.
     * IP QoS support. This enables setting the DSCP/Traffic Class field of
       IP/IPv6 packets sent by a client. For example starting a client with
       -qosdscp 184 marks all outgoing traffic for expedited forwarding.
       Implementation for Win32 is still a TODO, though.
     * Fixed hostname resolution problems under Windows.

   - SDLvncviewer
     * Is now resizable and can do key repeat, mouse wheel scrolling
       and clipboard copy and paste.

   - LinuxVNC:
     * Fix for no input possible because of ctrl key being stuck.
       Issue was reported as Debian bug #555988.
