cfd4a9a6d9 qt: always update the sink_retrieved flag when the sink retrieves 
Fixes a case where adding a qmlgloverlay element after an existing
qmlglsink elements was already in the pipeline would create an entirely
separate GstGLDisplay pointing to the same underlying display resource.

c7181bedac qt: return a different GstGLDisplay object when the first sink requests 
This allows the 'replace-gstreamer-opengl-context' context machinery to
correctly replace the OpenGL context used by the pipeline when the first
qmlglsink is added to the pipeline.

612102fdbc 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.

099712338f qt: Rework how we find the Qt QPA header 
Instead of querying the Qt include path from the dependency or from
qmake, rely on the qt5qml_dep to set the include path to QtGui
correctly, and look for the header inside the private includedir.

Then we can use that path to include the header directly.

4359684dd2 Revert "gl: Use GstGLDisplayEGL directly instead of creating a GstGLDisplayVIVFb subclass" 
This reverts commit 47fd4d391e.

This patch is incorrect. It doesn't actually compile, and causes a crash
because the viv-fb window implementation needs a native EGL handle
to pass to fbCreateWindow, but the GstGLDisplayEGL handleis actually
an EGLDisplay now (and gets cast to the wrong type)

43827a05f9 gl: Use GstGLDisplayEGL directly instead of creating a GstGLDisplayVIVFb subclass 
This simplifies the code a lot without any functional changes apart from
not closing the display connection. Closing the display connection is
not safe to do as it is shared between all other code in the same
process and no reference counting or anything happens at the platform
layer.

Sometimes wglCreateContextAttribsARB() exists, but
isn't functional (some Intel drivers), so it's
easiest to do the workaround unconditionally.
