Since aggregator introduced queueing in its sinkpads the way we set
properties on the pads is incorrect as it doesn't take it into account.
This fixes the issue by using the newly introduced `samples-selected`
signal in aggregator to set the properties right before the compositing
is done.
Also require the compositor we use to be an aggregator.
And add a validate test for it.

Smart rendering has been broken since, mostly forever, but some code
was there pretending it was supported... let's try to stop pretending.
We now keep track of the smart rendering state in the timeline, track
and sources to be able to:
* tell decodebin to stop plugging more (decoding elements) as soon as
downstream supports the format.
* avoid plugging converters after the source element when smart
rendering.

Stop setting the track 'caps' property. The previous code could
overwrite a users own setting of the caps for video and audio caps.
Moreover, the 'caps' property is listed as construct only, and users
will likely expect it to stay the same after a track has been added to a
timeline.

Stopping to do it at the bin description level but properly
plugging them where they are needed and cleanly ghosting the pads
where it makes most sense.
This introduces support for GES to request pads on the most upstream
element in case no static pad can be ghosted.

ges_uri_clip_asset_get_duration does not tell us what the duration in
the timeline needs to be. Especially when we have time effects, or
effects with finite max-durations. So we should no longer expect the
duration to stay the same when replacing assets. Instead, we just check
that the new max-duration would be compatible with the current in-point
(which was not checked before), and the clip would not be totally
overlapped if its duration-limit changes.
This is based on the assumption that each source is replaced one-to-one
in its track. If a source is replaced with nothing in the same track,
this check may be a little too strong (but still mostly weaker than
before). However, problems could occur if track selection does
something unexpected, such as placing the new source in a track not
previously occupied.

The out-point, which is an internal time, is used instead of the
duration for determining the control binding value at the end of the
element.
Also, allow the user to switch off the auto-clamping of control sources
if they are not desired. And allow them to clamp specific control sources
individually.
Also, fix a lot of memory leaks related to control sources. In
particular, releasing the extra ref gained by source in
g_object_get (binding, "control-source", &source, NULL);

If a layer priority sits between the priorities of two layers in the
timeline, i.e. it references a gap in the timeline's layers, then
ges_timeline_append_layer will never fill this gap and create the
desired layer, so the edit in timeline-tree would loop forever. So a
check was added to avoid this.
This would be a usage error, but a user can reasonably end up with a gap
in their layers if they remove a layer from the timeline.

Unlike ges_container_add, this lets you set the index and will check
that track selection did not fail. This is useful for time effects whose
addition would create an unsupported timeline configuration.
Also can use the clip add error in ges_timeline_add_clip to let the user
know when adding a clip to a layer that its in-point is set larger than
the max-duration of its core children.
