Auto transition when having 3 overlapping clips in a same point in the
timeline is not supported as we can't handle it in a nice way. Before we
to avoid creating 2 overlapping transitions (which is plain broken in
NLE) were completely disabling `auto-transition` and removing all
auto-transitions in the timeline but this is pretty weird for the end
user. This commit changes and now makes sure 2 transitions are not
created in the same place.
Also cleanup previous test case.
And start handling relocated assets.
Also expose the discoverer callback as a vmethod so that we can
overridde the discoverer when necessary (to handle discovering of
timeline through gesdemux for example)
When removing an effect from a clip, first the notify::priority signals
were being emitted for the remaining effects which changed priority, and only
at the end the child-removed signal. Now the child-removed signal is emitted
first.
Marking them as children properties and properly allow serializing
clips children properties.
This doesn't handle several TrackElement of a same type with
different property values but this require more worked already
marked as fixme to allow specifying full path of elements in the
children properties API.

Implementing it in the overrides as PyGObject won't be able to properly
convert python values to GValues in some cases. Using
g_object_set_property works as some logic is implemented inside
PyGObject for that particular case. This is a "regression" due
to https://bugzilla.gnome.org/review?bug=769789&attachment=348766 were
we end up with an OverflowError while setting G_TYPE_UINT children
properties.
In the (now tested) scenario where we have a transition on the right
side of a clip we are splitting, auto transitions can't be created
because we resize the clip after adding the new one, meaning that
there are 3 elements in the "transition zone", we need to force
auto transition creation after the splitting.

In some cases when rippling clip we could get the algo lost because
a transition existed between two clips (for example at the end of c1
and at the begining of c2) but while rippling it would have required
a transition at the end of c2 and beginning of c1, and we were properly
not destroying the old one (as the two clips were in the moving context)
but we were still creating the other transition in the end...

Computation was not taking into account the fact that the start of
the element being moved could be at the middle of a group and not
necessarily at the start!

We were only concidering that we should let the group handle moving
transitions when changing transitions but in fact as soon as a
transition is happenning between two clips that are in a same group
the group properly handles moving the transition, so let the
group do its job.

Fix all tests as we now have 1 priority inside the layer
dedicated to transitions (basically no source clip will
ever have a priority of 0 inside a layer).

Had to separate timeline_emit_group_added from timeline_add_group
to avoid emitting group-added when the project is being loaded.

And reuse the same previously created element when adding the clip
back to a layer, avoiding losing all setting done on clip children
in that situation
This is a behaviour change but previous behaviour was actually totally
unexpected and people working around that weird behaviour will moste
probably not care about that change

In get_property we should return the default values if
we have not created any GESTitleSource yet
(instead of segfaulting).
And fix GESTitleSource default values!

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.
