XAA PixmapOps: Sync before accessing unwrapped callbacks.
    
    When using any XAAPixmapOps, we call into unknown but freshly
    unwrapped callbacks (like fb ones). Unlike the XAA*Fallback calls,
    we did so without syncing first, exposing us to all kinds of
    synchronisation issues.
    
    I believe that the rendering errors appeared now because *PaintWindow
    vanished (e4d11e58), and we just use miPaintWindow instead. This
    takes a less direct route to the hw and ends up at
    PolyFillRectPixmap, which very often left drawing artifacts.
    
    We now sync accordingly, and no longer get the rendering artifacts i
    was methodically reproducing on radeonhd, radeon, unichrome...
    
    Also, in order to allow driver authors to remove extensive syncing
    or flushing to hide this issue, create XAA_VERSION_ defines, put
    them in xaa.h and bump the patchlevel.
    
    (novell bug #435791)
