[mach64] RENDER support (bug #6877).

RENDER accleration is disabled by default. It is strongly recommended that the
patch from bug #6772 and the 'exa-damagetrack branch' are merged in the xserver
before enabling RENDER acceleration. To enable RENDER acceleration, add the
following in xorg.conf:

Section "Device"
        [...]

        Option          "AccelMethod"           "exa"
        Option          "RenderAccel"           "true"
EndSection
