7066c849e4 glcontext: add support for influencing the backing configuration
New API:
- gst_gl_context_get_config()
- gst_gl_context_request_config()

A GL context configuration is a GstStructure that has some well-known
names for common values that can also be extended in platform-specific
ways if necessary.

Wrapped OpenGL contexts may be able to retrieve the GL context
configuration depending on the platform.  If that information is
available, GstGLContext will attempt to create an context that matches
the shared OpenGL context config unless gst_gl_context_request_config()
has been called.

A new environment variable 'GST_GL_CONFIG' will be read to influence the
configuration chosen.  The environment variable will only be used as a
fallback if gst_gl_context_request_config() has not been called.

e762f1b376 Revert "gstgldisplay: Add public foreign_display property"
This introduced a possible regression where the EGL display connection
could be leaked when a foreign native display (x11, wayland, etc) could
create a non-foreign EGL display that would never be destroyed.

The underlying problem needed to be solved in a different way.  See
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/640
for more details.

This reverts commit 2e686b0dad.

b4bdb75a80 gstglwindow_x11: fix resize
This patch was taken from #629#note_178766, the comment made
at the time was:

The root issue is a mismatch between the initialization of render_rect
in GstGLWindowX11Private and what's expected in the draw_cb function.
Because render_rect is not explicitly initialized to a width and height
of -1 (unlike gstglwindow_wayland_egl.c which does initialize to -1),
the less-than check for explicitly-set render_rect at gstglwindow_x11.c:453-454
always fails, even when the parent_win has been set and the render rectangle
has never been set.

Maybe this came from copying the similar check in the wayland code? Regardless,
I think the correct inequality should be '<= 0' (on both lines).

Alternatively initialization could be changed, but other sinks, e.g.
xvimagesink don't appear to use -1 to mean "unset" render_rect this way.

The issue can be reproduced by running the example in
tests/examples/gl/qt/videooverlay/ on X11, and resizing the output
window

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.

dc29bc4e13 libs: fix API export/import and 'inconsistent linkage' on MSVC
For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.

What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.

While we're at it, add new GST_API_EXPORT in config.h and use
that for GST_*_API decorators instead of GST_EXPORT.

The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.

We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.

The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h

Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.

This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

c5b5ef16d3 gl: GST_EXPORT -> GST_GL_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

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

4be04f8315 gl: don't export symbols that are not supposed to be public
Make a bunch of symbols private that are currently leaked
accidentally because they have a gst_* prefix and are used
internally. We mark those we can't make static with
G_GNUC_INTERNAL so that they get hidden with the autotools
build as well (although we could just pass -fvisibility=hidden
there too).

0e56bead42 gl/x11: use xcb instead of libX11
- xcb is supposedly thread-safe!

videotestsrc ! glimagesink now doesn't spuriously result in a
'call XInitThreads()' error however if anybody else is using X11,
then XInitThreads() still needs to be called and multiple glimagesink's
still need XInitThreads().

Everything still takes libX11 handles as they are compatible with the xcb
variants.  Unfortunately we cannot move fully over to xcb due to GLX being
entirely based on Xlib.  It's also impossible to transform a xcb_connection
to a Display which means we require X11 handles.

63bbe9406a glwindow: add API to request a resize event on the next draw
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.
