40364c2c09 libs: wayland: implement video overlay API
The Wayland sub-surfaces API is used to embed the video into an application
window.

See Appendix A. Wayland Protocol Specification as the following.

"""
The aim of sub-surfaces is to offload some of the compositing work
within a window from clients to the compositor. A prime example is
a video player with decorations and video in separate wl_surface
objects.

This should allow the compositor to pass YUV video buffer processing to
dedicated overlay hardware when possible.
"""

Added new method gst_vaapi_window_wayland_new_with_surface()

6c364cb9a7 libs: window: refactor as gobject
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.

15519ebe3d legal: add per-file authorship information.
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.
