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.

aggregator: Remove klass->sinkpads_type
...
This posed problems for the python bindings (and possibly others).
Instead, subclasses now use add_pad_template_with_gtype.

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

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.
