    Rewrite WaitQueue and WaitIdle accell macros
    
      WaitQueue() did receive an unused parameter, that was removed. The
    parameter was unused since version 1.0 in XFree86 CVS, so probably
    nobody knows for what it was used.
      WaitIdle() now also replaces WaitIdleEmpty(), as an idle engine
    should also have an empty fifo.
      SMI_SubsequentScreenToScreenCopy() was changed to use WaitIdle()
    instead of WaitQueue() before submitting the commands to the engine.
    This fixes a nasty lockup when using XaaOffscreenPixmaps (what is
    desired/wanted to help improve performance), and the lockup in the
    MSOC was clearly due to an engine overrun, when sending commands
    faster then the engine could process.
