4a006d6951 glcontext/egl: Fix build with upstream ANGLE
ANGLE_surface_d3d_render_to_back_buffer extension is only available
with Microsoft fork of ANGLE. Note that Microsoft's ANGLE repository
has been deprecated.

564ab3031b gstgl: Add a new window type for WinRT
This is needed for using GstGL with ANGLE as the GLES implementation
in Universal Windows Platform apps that use the Windows Runtime
(WinRT) instead of Win32, which is deprecated and not allowed in
Windows Store apps.

This has been tested with Servo on the Microsoft HoloLens 2, and seems
to work quite well.

5f70adf667 gl/egl/display: Add support EGLDevice display type
Simple addition for supporting EXT_platform_device typed display.
It's a kind of special display type (part of EGL specification)
which has no window at all.
To use EGLDevice explicitly, set environment "GST_GL_WINDOW=egl-device"

2e686b0dad gstgldisplay: Add public foreign_display property
We use this property in gst_gl_display_egl_from_gl_display, to set
foreign_display for the new GstGLDisplayEGL instance. This fixes a
problem where gst_gl_display_egl_finalize calls EglTerminate on a
pre-existing EGL connection.

574607702b Add GBM_CFLAGS and define EGL_PLATFORM_GBM_MESA
Building an image with yocto for an 'am335x' processor will fail,
because 'gbm.h' can not be found and 'EGL_PLATFORM_GBM_MESA' is not defined.

So simply adding define of 'EGL_PLATFORM_GBM_MESA' in 'gstgldisplay_egl.c'
and adding 'GBM_CFLAGS' in 'gst-gl.m4' to get rid of this errors and complete
a full build process.

ERRORs were:
-----------

54701ceb40 gl/display/egl: Fix precondition in display_egl_get_from_native
We don't really want type=NONE as input and it was already impossible
for that to occur with the other condtions.

4952fdd956 gl: do not include GL headers in public gstgl headers
Except for gst/gl/gstglfuncs.h

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

5efc2e8705 gl/egl: replace gsteglimagememory with an EGLImage wrapper
That can be passed to GstGLMemoryEGL.

This also ports the dmabuf uploader to GstEGLImage and GstGLMemoryEGL.

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.

c2471aec81 gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream
