b00c01ded7 timeline-tree: also trim non-core track elements
Also trim the in-point of non-core children of clips to ensure that
their content will appear in the timeline at the same position.

1cd72ed771 tests: add tests for new editing behaviour
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

cda1cfa0df timeline: emit snapping-started with new valid time
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.

39097f5574 timeline-tree: simplify and fix editing
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.

e41a6b6fac ges: Rework the way we ensure core elements are not wrongly moved between clips
Instead of focusing on the instances of the clips and their children,
we relax the check to allow moving track element clip between clips
that share a common asset. This makes it as correct conceptually but
more flexible, and the code becomes simpler.

278a5fd796 track-element: change owner to creator
Rename the private "owners" to "creators" to avoid confusing this with
the owner of the track element's memory.

Also made the ungroup method for GESClip symmetric by making all the
children of the resulting clips share their creators, which allows them
to be added to any of the other ungrouped clips. Once the clips are
grouped back together, the tracks loose these extra creators.

6b7c658b6a ges: Make setting start/duration move or trim generic
We were implementing the logic for moving/trimming elements specific
to SourceClip but this was not correct ass the new timeline tree allows
us to handle that for all element types in a generic and nice way.

This make us need to have groups trimming properly implemented in the
timeline tree, leading to some fixes in the group tests.

This adds tests for the various cases known to not be handled properly
by the previous code.

c750345c75 timeline: Better handle loading inconsistent timelines
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.

bd142e285d clip: Make sure to create transition after a clip is splitted
In the (now tested) scenario where we have a transition on the right

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.

1b5c3cb865 timeline: Avoid creating extra transition when rippling clips
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...
