98249a57db gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics
should be used instead.  GCC 11 has started warning about using volatile
with atomic operations.

21bc1040d4 glframebuffer: Don't do expensive checks with low gst debug levels
Framebuffer checks can be very expensive, taking up to 3-5% of the
total CPU consumed by the application.

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

1377a0a4f9 gldebug: make sure debug is initialized when calling gst_gl_insert_debug_marker
Usually gl debug is initialized in gst_gl_context_create_thread.
But this function is not used when using the GstGLContextGPUProcess
from ChromiumGStreamerBackend.

Received signal 11 SEGV_MAPERR 000000000000

a41f91253e gldebug: implement a delayed debug system
The messages are stored by gst_gl_async_debug_store_log_msg() and output later
by a corresponding store(), output() or an unset()/free().

Some wrapper macros are provided to avoid callers explicitly using __FILE__,
GST_FUNCTION and __LINE__

The string allocated by g_vasprintf() was leaked.

Reproduced using the
