timeline: re-handle clip children track selection
The way a clip's track elements are added to tracks was re-handled. This
doesn't affect the normal usage of a simple audio-video timeline, where
the tracks are added before any clips, but usage for multi-track
timelines has improved. The main changes are:
+ We can now handle a track being selected for more than one track,
including a full copy of their children properties and bindings.
(Previously broken.)
+ When a clip is split, we copy the new elements directly into the same
track, avoiding select-tracks-for-object.
+ When a clip is grouped or ungrouped, we avoid moving the elements to
or from tracks.
+ Added API to allow users to copy the core elements of a clip directly
into a track, complementing select-tracks-for-object.
+ Enforced the rule that a clip can only contain one core child in a
track, and all the non-core children must be added to tracks that
already contains a core child. This extends the previous condition
that two sources from the same clip should not be added to the same
track.
+ Made ges_track_add_element check that the newly added track element
does not break the configuration rules of the timeline.
+ When adding a track to a timeline, we only use
select-tracks-for-object to check whether track elements should be
added to the new track, not existing ones.
+ When removing a track from a timeline, we empty it of all the track
elements that are controlled by a clip. Thus, we ensure that a clip
only contains elements that are in the tracks of the same timeline, or
no track. Similarly, when removing a clip from a timeline.
+ We can now avoid unsupported timeline configurations when a layer is
added to a timeline, and already contains clips.
+ We can now avoid unsupported timeline configurations when a track is
added to a timeline, and the timeline already contains clips.

timeline: re-handle clip children track selection
The way a clip's track elements are added to tracks was re-handled. This
doesn't affect the normal usage of a simple audio-video timeline, where
the tracks are added before any clips, but usage for multi-track
timelines has improved. The main changes are:
+ We can now handle a track being selected for more than one track,
including a full copy of their children properties and bindings.
(Previously broken.)
+ When a clip is split, we copy the new elements directly into the same
track, avoiding select-tracks-for-object.
+ When a clip is grouped or ungrouped, we avoid moving the elements to
or from tracks.
+ Added API to allow users to copy the core elements of a clip directly
into a track, complementing select-tracks-for-object.
+ Enforced the rule that a clip can only contain one core child in a
track, and all the non-core children must be added to tracks that
already contains a core child. This extends the previous condition
that two sources from the same clip should not be added to the same
track.
+ Made ges_track_add_element check that the newly added track element
does not break the configuration rules of the timeline.
+ When adding a track to a timeline, we only use
select-tracks-for-object to check whether track elements should be
added to the new track, not existing ones.
+ When removing a track from a timeline, we empty it of all the track
elements that are controlled by a clip. Thus, we ensure that a clip
only contains elements that are in the tracks of the same timeline, or
no track. Similarly, when removing a clip from a timeline.
+ We can now avoid unsupported timeline configurations when a layer is
added to a timeline, and already contains clips.
+ We can now avoid unsupported timeline configurations when a track is
added to a timeline, and the timeline already contains clips.

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.
