gst_vaapi_display_egl_new_with_native_display() has been broken since
it wasn't used.
Currently it's needed to call this API to create a display providing
the EGL display, so it could avoid duplicated calls to the native
display (eg. eglTerminate).

eglGetDisplay() is currently broken in Mesa for Wayland. Also using
eglGetDisplay() is rather fragile, and it is recommended to use
eglGetPlatformDisplay() when possible.
In order to do that, this patch uses the helper in GstGL. If
gstreamer-vaapi is not compiled with GstGL support, eglGetDisplay()
will be used.

Adds a new function that changes the internal EGL display to the
current one (eglGetCurrentDisplay()) and sets the current context
too (eglGetCurrentContext()).
This new function is called by gst_vaapi_texture_egl_create() updating
the GstVaapiDisplayEGL with the current EGL display.

GstVaapiDisplayEGL is a wrapper of another GstVaapiDisplay, either X11
or Wayland. Nonetheless it created another vaDisplay for it, instead
of using the wrapped one.
This patch enables the reuse of the wrapped vaDisplay avoiding
instantiating two.

This patch is to change the inheritance of GstVaapiDisplay to GstObject,
instead of GstVaapiMiniObject. In this way we can use all the available
infrastructure for GObject/GstObject such as GstTracer, GIR, etc.
In addition, a new debug category for GstVaapiDisplay is created to make it
easier to trace debug messages. It is named "vaapidisplay" and it transverse
all the VA display backends (DRM, GLX, EGL, Wayland, ...)
This patch is a step forward to expose GstVaapiDisplay for users in a future
library.

instances when created and reuse
This patch improves performance when glimagesink uploads a GL texture.
It caches the GStVaapiTexture instances in GstVaapiDisplay{GLX,EGL}, using an
instance of GstVaapiTextureMap, so our internal texture structure can be found
by matching the GL texture id for each frame upload process, avoiding the
internal texture structure creation and its following destruction.

Since the upstream of gstreamer-vaapi, the library is not a public shared
object anymore. But the EGL support depended on this dynamic library, so the
EGL support was broken.
This patch removes the dynamic library loading code and instantiates the
EGL display using either X11 or Wayland if available.

As gst-indent generated ugly code in these cases, this patch changes the used
idiomatic into other one.
No functional changes were introduced.

Add GstVaapiTextureEGL abstraction that can create its own GL texture,
or import a foreign allocated one, while still allowing updates from a
VA surface.
Add initial support for EGL to libgstvaapi core library. The target
display server and the desired OpenGL API can be programmatically
selected at run-time.
A comprehensive set of EGL utilities are provided to support those
dynamic selection needs, but also most importantly to ensure that
the GL command stream is executed from within a single thread.
