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.

7b5f655c9a ges-source-clip: fixed return of duration setter
In general, brought the behaviour of the `start`, `duration` and
`inpoint` setters in line with each other. In particular:
1. fixed return value the GESSourceClip `duration` setter
2. changed the GESClip `start` setter
3. fixed the inpoint callback for GESContainer
4. changed the type of `res` in GESTimelineElement to be gint to
   emphasise that the GES library is using the hack that a return of -1
   from klass->set_duration means no notify signal should be sent out.

Also added a new test for clips to ensure that the setters work for
clips within and outside of timelines, and that the `start`, `inpoint`
and `duration` of a clip will match its children.

d87578c843 element: Make return value of setters mean something
Setters return values should return %FALSE **only** when the value
could not be set, not when unchanged or when the subclass handled
it itself!

This patches makes it so the return value is meaningul by allowing
subclasses return anything different than `TRUE` or `FALSE` (convention
is -1) to let the subclass now that it took care of everything and
no signal should be emited.

a46390ff56 Reimplement the timeline editing API
This is implemented on top of a Tree that represents the whole timeline.

SourceClips can not fully overlap anymore and the tests have been
updated to take that into account. Some new tests were added to verify
that behaviour in greater details

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

a66e674649 Include class related section documentation in the gir file.
g-ir-scanner includes section docs as class/interface docs if the section name is equal to the lowercase type name.
Since all the documentation is in section blocks, rename them to match the type names.
