Update xorg to 6.8.2.

Changes:

    * Render implementation fixes
    * Updated x86emu and resynced with upstream at Scitech
    * Updated SiS driver
    * Updated Nvidia driver (opensource version)
    * Render acceleration for ATI's R100 and R200-series cards
    * Substantial speedups in the software implementation of the render
      extensions when compiled with gcc 3.4 on the i386 architecture.
    * Infrastructure for rotation support in drivers
    * New Trapezoid specification for the Render extension

      "XpExtension")can now be enabled/disabled from the configuration
      file and from the command line.
