This is another step in the gobjectification of the internal library of gstreamer-vaapi. Now it is the turn of GstVaapiWindow and its derivates. The idea is to minimize the changeset keeping the same design as much as possible. GstVaapiWindow is defined as an abstract class with two properties: the GstVaapiDisplay and the native ID. Thus, many of the GstVaapiObject macros were copied as GstVaapiWindow macros. The function gst_vaapi_window_new_internal() is kept as a decorator of for calling gst_vaapi_window_create() and the possibility of failure. The descendant classes, such as glx, still use the private structures, but through the gobject mechanism.
