    XQuartz: xpr: Use a serial queue rather than pthread mutexes for window_hash
    
    Additionally removes some dead code and fixes double-locking in
    xprIsX11Window.  xprIsX11Window doesn't need to do any locking because
    those resources are protected by the called functions themselves.

    XQuartz: Use a lighter spinlock instead of a pthread_mutex_t in QuartzScreenSaver
    
    Currently, we only end up here through a call to QuartzShowFullscreen, and
    this is always on the same thread.  Future changes (such as further
    incorporating libdispatch) may allow this to change, but contention will
    remain minimal since the call is infrequent and it is short held.

    XQuartz: Remove the threadSafety dead-ish code
    
    It's been a few years now since we've needed this to debug thread
    boundaries, so punt it out to clean up the namespace polution.

    xorg_backtrace() has been in os for two years now, we might as well
