fc0333922f ges: Make it so core elements can be re added to their 'owners'
The user might want to add/remove/add core children to clips and be able
to regroup ungrouped clip. This is needed for undo/redo in Pitivi for
example

91b5a5804a clip: only allow core elements as children
Only allow elements that were created by ges_clip_create_track_elements
(or copied from such an element) to be added to a clip. This prevents
users from adding arbitrary elements to a clip.

As an exception, a user can add GESBaseEffects to clips whose class
supports it, i.e. to a GESSourceClip and a GESBaseEffectClip.

This change also introduces a distinction between the core elements of a
clip (created by ges_clip_create_track_elements) and non-core elements
(currently, only GESBaseEffects, for some classes). In particular,
GESBaseEffectClip will now distinguish between its core elements and
effects added by the user. This means that the core elements will always
have the lowest priority, and will not be listed as top effects. This is
desirable because it brings the behaviour of GESBaseEffectClip in line
with other clip types.

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.

a8458d59de timeline: fix layer priority argument in trim
Previously, we tested that the given priority was `>0`, when it seems
that `>=0` was intended. A priority of `-1` means leave the priority
unchanged, whilst a priority of 0, or more, means move to this layer
priority.

615bf9e47a timeline: fix paste ownership
The method steals ownership of `copied_from`, so should be responsible
for unreffing it. Also make sure we fail when `layer != -1`, since this
functionality is not supported.

35d140ad92 Don't pass default GLib marshallers for signals
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.

Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.

31ccb3106f timeline: Do not post upstream translated composition update messages
In the case of nested timeline in the toplevel timeline we ended up
with CompositionUpdate for seeks sent by our own composition to
granchildren composition. This was not causing essential issues
if all tracks where containing nested timelines but in cases
where one of the tracks only had a nested timelines, then we
were waiting forever for a `CompositionUpdateDone`.

CompositionUpdate translated into ASYNC_START/ASYNC_DONE should
be kept inside the GESTimeline and not travel up (possibly to some
parent GESTimeline).

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.

a7347ca8f7 WIP: ges: fix API export/import and 'inconsistent linkage' on MSVC
Export GES library API in headers when we're building the
library itself, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

Fix up some missing config.h includes when building the lib which
is needed to get the export api define from config.h

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
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.

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...
