b769f02261 gldisplay: Prefer wayland over X11
As most Wayland compositors supports XWayland, X11 backend get
selected. This also realign better GStreamer decision to what
happens with GTK and other stack out there.

697cd40ee4 gldisplay: fix list leak
Windows aren't always removed in time, and it turns out to be
very, very hard to remove a window in a way that's not racy and
not deadlocky. Since the window itself doesn't leak, freeing
the list on object destruction is enough.

ecfe5b0801 gl: implement GstGLMemoryEGL
Because current GstEGLImageMemory does not inherit GstGLMemory, GLUpload
allocates additional GLMemory and upload the decoded contents from the decoder
which uses EGLImage (e.g. gst-omx in RPi).

This work adds GstGLMemoryEGL to avoid this overhead. Decoders allocate
GstGLMemoryEGL and decode its contents to the EGLImage of GstGLMemoryEGL.  And
GLUpload uses this memory without allocation of additional textures and blit
operations.

[Matthew Waters]: gst-indent the sources and fix a critical retreiving the egl
display from the memory.

eb1a9bb9b0 gldisplay: make readding the same context a no-op
With e38af23044 returning the correct contexts,
gst_gl_display_add_context() was susceptible to causing infinte loops when
adding the same GstGLContext more than once.  Fix and add a test for
gst_gl_display_add_context().

Fixes glvideomixer gst-validate tests.

However, when requesting current glcontext on a specific thread, it could

76a38dd66a glmemory: base classify and add the pbo memory on top
The base class is useful for having multiple backing memory types other
than the default.  e.g. IOSurface, EGLImage, dmabuf?

The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.

This also moves the format utility functions into their own file.

9f704d7c2d gl/wayland: add GstGLDisplayWayland
Simple implementation split from GstGLWindowWayland

Can now have multiple glimagesink elements all displaying output
linked via GL or otherwise (barring GL platform limitations).

The intel driver is racy and can crash setting up the two glimagesink contexts.

e.g.
videotestsrc ! tee name=t ! queue ! glupload ! glimagesinkelement
  t. ! queue ! gleffects_blur ! glimagesinkelement

videotestsrc ! glupload ! glfiltercube ! tee name=t ! queue ! glimagesinkelement
  t. ! queue ! gleffects_blur ! glimagesinkelement

bcce615263 gl: add a scary note about initializing thread support for the winsys
We cannot do it as the winsys may crash if we initialize too late.

Example, GLX contexts with Intel drivers:
Intel requires the X Display to be the same in order to share GL
resources across GL contexts.  These GL contexts are generally
accessed from different threads.  Without winsys support it is
nearly impossible to guarentee that concurrent access will not
occur.  This concurrent access could result in crashes or abortion
by the winsys (xcb).

5433010ab5 gl/wayland: create a dummy display instead of an EGLDisplay
Currently, GstGLWindowWaylandEGL holds the wayland display connection
If we create the EGLDisplay at the GstDisplay creation time, then
libEGL will internally open another connection to the wayland server.
These two display connections are unable to communicate resulting in
no window output/display and hangs inside libEGL.

Eventually we will move the wl_display from GstGLWindow to GstGLDisplay.
