2fae9ee50d group: Make deep copying actually copy deep
Allowing pasting groups paste exactly what had been copied

And not the new version of the contained objects

This technically breaks the C API but this is a new API and I believe
and hope nobody is using it right now.

b75d9b11c6 Revert "timeline-element: Do not consider not serializable elements when getting top element"
This commit was causing issue where we were reporting the toplevel
element as an element but that element was actually in another
not serialized group. That is very tricky to handle for end users
as they are not guaranteed the toplevel clips were actually not
contained in another element.

This reverts commit ceb82ba302.

fcf8d5382e formatter: Do not serialize top effect priorities
We just need to make sure they are always serialized in the right
order (which is the case) and de serializing them will lead to the
right behaviour.

We should not serialize the priority as the priority of the source
itself depends on the action having been done on the parent clip,
and we do not serialize the source priorities (and should not, GES
should just do the right thing).

Summary: It must only be done when the object is commited.
We can do that in constructed though, as the changes will
anyway be commited when the object is added to a composition.

Also update the tests, as we set properties spearately then
check the stop, we can commit the source at its creation without
removing meaning from the tests.

We were emitting commited when timeline_commit was called, which
wasn't very helpful. This commit makes it so we emit commited once
all the compositions have actually been commited.

We also add a synchronous commit method to spare the user
the need to connect to the signal and wait, and update the

Otherwise if there was still a reference to the layer when it
is removed from the timeline, it fails when the last reference
is released, because timeline_element_set_timeline calls
timeline_remove_element, which tries to remove the element from

20f76fe86f trackelement: Add a lookup_child vmethod
This method can be used for subclass to override the default behaviour
for child lookup. This vmethod can be used for example in the case where
you want the name of a child property to be 'overridden'.

As an example in the GESTitleSource where we have a videotestsrc
which has a 'foreground-color' property that is used in the TitleSource
to set the background color of the title, this vmethod is now used to
tweak the name passed as parameter to rename "background" to
"foreground-backend" making our API understandable.

API:
  GESTrackElement::lookup_child

19ee23cdcc nlecomposition: update base time before seeking current stack.
There could be a race where the new segments were pushed after
a seek on some / all pads before the operation had had its basetime
updated, and thus incoming segments were tweaked wrongly.

Reproducible with 3 clips composited and multiple seeks,
FIXME hard to validate.

50cf1fb5fe nlecomposition: Fix several leaks
* In the action closure invokation we were alway leaking the composition.
* gst_bin_add will actually take an extra ref since we already  gst_object_ref_sink so we
own the object, other call to that method will increase the refcount which means we do
not need to pass an extra ref to the bin.
* We want to ref_sink right when the object is added to the composition, making things
cleaner and simpler to follow in the tests.

"pad: don't accept flush-stop on inactive pads" in -core, the flush_stop event will not be
fowarded downstream in case the pad is not activated. In our case the element is in
READY state, so pads are deactivated. In that commit we simply make sure that the
event can be fowarded downstream
