Added workable QScreen API on top of QPlatformScreen.
QPlatformIntegration::screens() no longer has to be implemented, implementations should call QPlatformIntegration::screenAdded() for each screen instead. This is for being able to support adding screens at run-time later on, by connecting it to a signal in QGuiApplication. The QGuiGLContext API has changed a bit, by not sending in all the parameters in the constructor but instead having a create() function. The createPlatformGLContext() factory in QPlatformIntegration takes a QGuiGLContext * instead of a QSurfaceFormat and a share context, similar to how the window and backing store factory functions work. The XCB plugin has experimental support for connecting to multiple X displays simultaneously, creating one or more QScreen for each.
