      Description

      This will make it simpler to port Qt4/Xlib based
      applications to Qt5 when Qt4 based application
      uses Xlib's event handling APIs directly such as:
      XNextEvent+XPutBackEvent and XPeekEvent. It
      is not possible to use those with Qt5 because
      we set XCB to be the owner of X event queue with:

      XSetEventQueueOwner(dpy, XCBOwnsEventQueue);

      Which means that only xcb event handling functions
      can be used to read events from X server. XCB does
      not have equivalents for the above mentioned Xlib APIs.
      peekEventQueue() adds this behavior to QX11Info.
