Make less assumptions about the priority of effects and core elements so
that the code would still work if the priority of an element was set
directly. In particular, the index of a top effect will always be its
position in the effect ordering.

We first change the duration of the splitted clip, then we add the new
clip to the layer and assign the tracks for its children. Normally, when
a clip is added to a layer it will have its track elements created, if
needed, and then assigned to their tracks. This will fail if any sources
would fully or triple overlap existing sources in the same track.
However, here we were adding the clip to the layer *and* avoiding the
track assignment process and instead setting the tracks explicitly. In
particular, the order was:
+ add new clip to layer with no tracks assigned
+ shrink the split clip
+ assign the tracks for the new clip
This has been changed to:
+ shrink the split clip
+ add new clip to layer with no tracks assigned
+ assign the tracks for the new clip
Thus, the order of events for any users connecting to object signals
will be close to that of adding another clip to the layer.

Any time a track element is added to a track, we need to check whether
we need to create a new corresponding auto-transition. This simply moves
the code from ges-clip.c to ges-timeline.c, where it is more appropriate.
Moreover, it technically opens the possibility for creating
auto-transitions for track elements in the timeline that have no
corresponding clip.

Make sure that the priority of an appended layer is the lowest (highest
in value) when appending a layer to the timeline. This change is
important when appending a layer to a timeline, which can easily have a
gap in priorities if a layer has been removed.

These tests expose some of the new editing behaviour in timeline
tree. In particular, we test:
+ edits for clips within groups within a group
+ that an edit can succeed if a snap allows it to
+ that snapping occurs at a specific point, and that we alternate
between one call to snapping-started and one call to snapping-ended
with corresponding values
+ that an edit can fail if a snap causes it to
+ no snapping is released when an edit fails
+ We tests for the expected changes, and otherwise check that the
configuration of the timeline has remained unchanged
+ The timeline configuration remains the same when an edit fails
+ That each clip overlap has a corresponding auto-transition
+ That particular auto-transitions are created when a new overlap is
formed
+ That particular auto-transitions are destroyed when an overlap ends
+ That auto-transitions are not replaced when two clips move but
maintain their overlap
+ That the timeline does not contain any unaccounted for clips
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/169>
Since a group can only have its priority set whilst it is part of a
timeline, we can simply let the timeline-tree handle the move, which it
can already do, whilst checking that the move would be legal (not break
the timeline configuration). All the group has to do now if update its
priority value if the priority of any of its children changes. It
doesn't even need to keep track of the layer priority offsets.
Also, added a check to ensure added children belong to the same
timeline.
Also moved the sigids from the GObject data to a g_hash_table, which is
clearer.

It should be sufficient to set the edit flag only on the toplevel, which
allows all of its children to know they are being edited and should not
move in response.
Also, removed some unnecessary setting/checking of this.
Also, supplied the ges_timeline_element_peak_toplevel, which unlike
ges_timeline_element_get_toplevel_parent, does not add a reference to
the toplevel. Some corresponding leaks in auto-transition have been
fixed by using this instead.

Only emit snapping-ended if we have a valid snap time. Moreover, we
should emit a new snapping-started even if we are snapping at the same
location. This is because a new snap will always correspond to a new edit,
possibly involving different snapping elements, which a user would want
to know about.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/169>
Editing has been simplified by breaking down each edit into a
combination of three basic single-element edits: MOVE, TRIM_START, and
TRIM_END.
Each edit follows these steps:
+ Determine which elements are to be edited and under which basic mode
+ Determine which track elements will move as a result
+ Snap the edit position to one of the edges of the main edited element,
(or the edge of one of its descendants, in the case of MOVE), avoiding
moving elements.
NOTE: in particular, we can *not* snap to the edge of a neighbouring
element in a roll edit. This was previously possible, even though the
neighbour was moving!
+ Determine the edit positions for clips (or track elements with no
parent) using the snapped value. In addition, we replace any edits of
a group with an edit of its descendant clips. If any value would be
out of bounds (e.g. negative start) we do not edit.
NOTE: this is now done *after* checking the snapping. This allows the
edit to succeed if snapping would cause it to go from being invalid to
valid!
+ Determine whether the collection of edits would result in a valid
timeline-configuration which does not break the rules for sources
overlapping.
+ If all this succeeds, we emit snapping-started on the timeline.
+ We then perform all the edits. At this point they should all succeed.
The simplification/unification should make it easier to make other
changes.

Simplified keeping the start and the duration of a container/group up to
date with the earliest start of the children and the last end of the
children. The previous logic was spread between ges-group and
ges-container, now all the position handling is in ges-container.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/169>
The duration-limit is the maximum duration that can be set for the clip
given its current children and their properties. If a change in the
children properties causes this to drop below the current duration, it
is automatically capped by this limit.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-editing-services/-/merge_requests/169>
If `add_child` and `set_parent` succeed we want to return TRUE, even if
the added element is no longer a child by the end of the method. This is
because some users may call ges_container_remove during `child-added`.
This shouldn't be considered an error.
The case was that the timeline state was being changed from the parent
composition's action thread before the timeline was committed, leading
to the SELECT_STREAM event to be pushed from the track to the nested
timeline from the wrong composition thread.

Made sure that adding a new track only uses select-tracks-for-object for
core children to determine whether a track elements should be added to the
new track or not, and *not* any other track. In particular, there should
be *no* change in the existing tracks of the timeline when adding another
track. Moreover, a new track should not invoke the creation of track
elements for other tracks.

The property had been deprecated and is unused.
This property is not needed. Any internal time effect that an nleoperation
wraps is itself responsible for converting seek/segment timestamps.
Previously, the ghostpads were performing a rate conversion after the
rate element had already done so, essentially doubling their effect on
seeks and segment times. This was always unnecessary, but went unnoticed
by the tempochange test because it was using an identity element rather
than an actual rate-changing element.

Avoid loosing (too much) precision when rescaling back and forth by
storing values in gdoubles.
Handle the fact that position values can be negative
Also fix debug category static variable
as it clashes with the instance variable name in a few methods.
