5d47b8e232 gl: fix application context querying between elements 
Fixes error introduced by:
a4e49ba8c9
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/642

Using the application GL context as the local GL context is not going to
work very well.

a4e49ba8c9 gl: avoid deadlock querying for OpenGL context 
If there are two elements and threads attempting to query each other for
an OpenGL context. The locking may result in a deadlock.

We need to unlock each element's context_lock when querying another
element for the OpenGL context in order to allow any other element to
take the lock when the other element is querying for an OpenGL context.

33a8e28207 videoaggregator: Switch to a GstVideoAggregatorConvertPad subclass 
This moves all the conversion related code to a single place, allows
less code-duplication inside compositor and makes the glmixer code less
awkward. It's also the same pattern as used by GstAudioAggregator.

14f886b7b0 aggregator: Remove klass->sinkpads_type 
This posed problems for the python bindings (and possibly others).

Instead, subclasses now use add_pad_template_with_gtype.

11bb4454a8 glvideomixer: fix race retrieving the GL context from the display 
_get_gl_context() can be called concurrently from either propose_allocation() or
decide_allocation().  If it so happens that this happens at the same time,
the check for whether we already had a GL context was outside the lock.  Inside
the lock and loop, the first thing that happens is that we unref the current GL
context (if valid) as if there was a conflict adding it to the display.  If the
timing was unlucky, subsequent use of the GL context would be referencing an
already unreffed GL context object resulting in a critical:

g_object_ref: assertion 'object->ref_count > 0' failed

96682c41d4 glbasemixer: actually attempt to propose an allocation upstream 
We were always failing the allocation query as a flag was never being set to
signal a successful negotiation.  Fix by setting the required flag on a
successful caps event from upstream.
