When direct rendering is enabled, use hostdata blits to transfer data from

    system memory to video RAM, which should reduce CPU usage especially
    with larger videos. Can be disabled via Option "DMAForXv" if there
    should be any stability issues, but it's been stable for me during a
    week of testing. Based on a patch by Nikolaus Meine
    <meine@tnt.uni-hannover.de>. Probably fix endianness issues in some
    newer XVideo code, untested.
Also use hostdata blits to transfer RENDER image data to video RAM to avoid
    idling the accelerator engine. Increases RENDER performance
    significantly for me.
These changes were only tested on an M9 in a Titanium PowerBook but should
    work with all Radeons where direct rendering is supported.
