Add gst_vaapi_window_reconfigure() interface to force an update of
the GstVaapiWindow "soft" size, based on the current geometry of the
underlying native window.
This can be useful for instance to synchronize the window size when
the user changed it.
Thanks to Fabrice Bellet for rebasing the patch.

Add API to transfer VA urfaces to native pixmaps. Also add an API to
render a native pixmap, for completeness. In general, rendering to
pixmap would only be useful to certain VA drivers and use cases on
X11 display servers. e.g. GLX_EXT_texture_from_pixmap (TFP) handled
in an upper layer.
Drop obsolete GST_VAAPI_IS_xxx() helper macros since we are no longer
deriving from GObject and so those were only checking for whether the
argument was NULL or not. This is now irrelevant, and even confusing
to some extent, because we no longer have type checking.
Note: this incurs more type checking (review) but the libgstvaapi is
rather small, so this is manageable.
