    DRI2: Make setTexBuffer take a __DRIdrawable instead of a BO handle.
    
    This fixes a problem where texturing from the same Pixmap more than
    once per batchbuffer would hang the DRI driver.  We just use the region
    associated with the front left renderbuffer of the __DRIdrawable for
    texturing, which avoids creating different regions for the same BO.
    
    This change also make GLX_EXT_texture_from_pixmap work for direct
    rendering, since tracking the __DRIdrawable -> BO handle now uses
    the standard DRI2 event buffer.  Of course, DRI2 direct rendering
    doesn't exist yet.
    
    Finally, this commit bumps the DRI interface version again, accounting
    for the change in the DRI_TEX_BUFFER extension and the change in
    commit 0bba0e5be7a4a7275dad1edc34bdcc134ea1f424 to pass in the
    event buffer head index on drawable creation.

    DRI2: Drop DriverAPI.UpdateBuffer.
    
    __dri2ParseEvents() would determine the kind of event, but then call
    UpdateBuffer() in either case, and UpdateBuffer() would then have to
    figure that out again to dispatch to HandleBufferAttach() or
    HandleDrawableConfig().  Pretty pointless.

    DRI2: Pass the context instead of the screen to __dri2ParseEvents().
    
    Makes a lot more sense, since the screen is always implicit in the
    DRI drawable, but it may not be possible to track down a context from
    just a drawable.

    DRI2: Add event buffer head as an argument to driCreateNewDrawable().
    
    The DRI driver needs to know where in the buffer to start reading.
