Previously, the GESContainer ->paste method and GESGroup ->paste methods
were unnecessarily setting the timeline of groups, even though this is
handled by the GESGroup ->child_added method. This could result in the
group being added multiple times.
And deprecate all GESTrackElement constructors, but the GESEffect one.
Those should **never** be created by users and should become internal
in the future.
Stop having docstring for the constructors that were internal.
As such, they only emit a signal if their value changes, either through
their _set_inpoint or _set_max_duration methods, or through
g_object_set, etc.
Also, we now require the ->set_max_duration method to be implemented.
This was added to GESGroup, which will only allow the max-duration to be
set to GST_CLOCK_TIME_NONE.
Hold the notify signals for the container and the children until after
the child has been fully added or removed.
After the previous commit, this was used to ensure that the
notify::priority signal was sent for children of a clip *after* the
child-removed signal. This stopped being the case when the code in
->child_removed was moved to ->remove_child (the latter is called before
the child-removed signal is emitted, whilst the former is called
afterwards). Rather than undo this move of code, which was necessary to
ensure that ->add_child was always reversed, the notify::priority signal
is now simply delayed until after removing the child has completed. This
was done for all notify signals, as well as in the add method, to ensure
consistency.
This allows the test_clips.py test_signal_order_when_removing_effect to
pass.
Also make subclasses take a copy of the list of the children before
setting the start and duration, since this can potentially re-order the
children (if they have the SET_SIMPLE flag set).
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.
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
Each timeline element is in a layer (potentially spanning
over several), it is very often useful to retrieve an element
layer priority (from an app perspective more than the element
priority itself as that is a bit of an implementation detail
in the end).
Port tests to it
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

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

This is formally an API break but I am sure no one ever used that and
we should make sure the method is removed as soon as possible because
it has no reason to be exposed.
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.

This means we need to properly track the layer a clip was in. We now
keep track of the various signal IDs in a dedicated structure and
keep a ref on the layer an object is in.

They were not serialized until now.
That implies several changes:
* Override GESTimelineElement [start, inpoint, duration] properties in
GESGroup to ensure that those properties are not serialized as they
should not be.
* Rename GESBaseXmlContainer->clips field to
GESBaseXmlContainer->containers as the hashtable now contains Groups

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.
