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.

Currently the .la path is provided which requires to use libtool as
mentioned in the GStreamer manual section-helloworld-compilerun.html.
It is fine as long as the application is built using libtool.
So currently it is not possible to compile a GStreamer application
within gst-uninstalled with CMake or other build system different
than autotools.
This patch allows to do the following in gst-uninstalled env:
gcc test.c -o test $(pkg-config --cflags --libs gstreamer-1.0 \
gst-editing-services-1.0)
Previously it required to prepend libtool --mode=link

Read only properties will throw a GLib warning like this
when accessed with "set_child_property":
Warning: g_object_set_property: property 'text-x' of object class 'GstTextOverlay' is not writable
Those error are really critical and we are then enable to keep
working. Just post an ERROR message on the bus and let the
application deal with it.

Avoiding all the pending_xx dance and making the code simpler.
This is now possible thanks to the various recent refactoring.
Thanks to that the user is able to set_child_property on objects
that are not in GESTrack yet, as expected.

In get_property we should return the default values if
we have not created any GESTitleSource yet
(instead of segfaulting).
And fix GESTitleSource default values!

This way we have informations about the content of the

Most code paths where already ready to handle that as we use it for
copying clips.
Fix framepositionner to properly handle that (it would have broke
with copied clips before).

This technically breaks the C API but this is a new API and I believe
and hope nobody is using it right now.

This commit was causing issue where we were reporting the toplevel
element as an element but that element was actually in another
not serialized group. That is very tricky to handle for end users
as they are not guaranteed the toplevel clips were actually not
contained in another element.
This reverts commit ceb82ba302.
