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.

c12b84788d asset: move set_proxy (NULL, proxy) behaviour to new method
We should not be accepting ges_asset_set_proxy (NULL, proxy) as part of
the API! This behaviour was used internally in combination with
ges_asset_try_proxy, which is called on a still loading asset, so it was
moved to ges_asset_finish_proxy.

7b3ac927dc ges: Add a method to retrieve the 'natural' size of VideoSource
This way the user can easily know how the clip would look like
if no scaling was applied to the clip, this is useful to be able
to properly position the clips with the framepositionner element.

c802a40a96 ges: Call the right ->set_child_property vmethod
We used to always call the `->set_child_property` virtual method
of the object that `ges_timeline_element_set_child_property` was called
from, but that means that, in the case of referencing GESContainer
children properties from its children, the children wouldn't know
what child property have been set, and the children override wouldn't
be takent into account, in turns, it means that the behaviour could be
different in the setter depending on parent the method was called,
which is totally unexpected.

We now make sure that the vmethod from the element that introduced the
child property is called whatever parent method is called, making the
behaviour more uniform.

Fix the python override to make sure that new behaviour is respected.

82159882d7 ges: Ignore deprecation of GParameter
GParameter is part of our API, and for GLib < 2.54 we do not even have

We should stop using GParameter once we depend on GLib 2.54.

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.

84f7f04a64 Handle changing playback rate
Before this patch, NLE and GES did not support NleOperations (respectively
GESEffects) that changed the speed/tempo/rate at which the source plays. For
example, the 'pitch' element can make audio play faster or slower. In GES 1.5.90
and before, an NleOperation containing the pitch element to change the rate (or
tempo) would cause a pipeline state change to PAUSED after that stack; that has
been fixed in 1.5.91 (see #755012 [0]). But even then, in 1.5.91 and later,
NleComposition would send segment events to its NleSources assuming that one
source second is equal to one pipeline second. The resulting early EOS event
(in the case of a source rate higher than 1.0) would cause it to switch stacks
too early, causing confusion in the timeline and spectacularly messed up
output.

This patch fixes that by searching for rate-changing elements in
GESTrackElements such as GESEffects. If such rate-changing elements are found,
their final effect on the playing rate is stored in the corresponding NleObject
as the 'media duration factor', named like this because the 'media duration',
or source duration, of an NleObject can be computed by multiplying the duration
with the media duration factor of that object and its parents (this is called
the 'recursive media duration factor'). For example, a 4-second NleSource with
an NleOperation with a media duration factor of 2.0 will have an 8-second media
duration, which means that for playing 4 seconds in the pipeline, the seek
event sent to it must span 8 seconds of media. (So, the 'duration' of an
NleObject or GES object always refers to its duration in the timeline, not the
media duration.)

To summarize:

* Rate-changing elements are registered in the GESEffectClass (pitch::tempo and
  pitch::rate are registered by default);
* GESTimelineElement is responsible for detecting rate-changing elements and
  computing the media_duration_factor;
* GESTrackElement is responsible for storing the media_duration_factor in
  NleObject;
* NleComposition is responsible for the recursive_media_duration_factor;
* The latter property finally fixes media time computations in NleObject.

NLE and GES tests are included.
