The underlying integer type for enums are implementation defined and may

In some cases when rippling clip we could get the algo lost because
a transition existed between two clips (for example at the end of c1
and at the begining of c2) but while rippling it would have required
a transition at the end of c2 and beginning of c1, and we were properly
not destroying the old one (as the two clips were in the moving context)
but we were still creating the other transition in the end...

Debugging must be configuring first (before any parsing), and then
the types are initialized at the end.
Fixes issues with debugging categories not being available at the
start
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.

We should never let 3 objects to overlap at a same position, for that
we introduce a "rollback" feature and whenever such an editing happens,
we rollback object position to whatever it was before the move.
In case of groups, we can have track elements that do not belong
directly to the moved_trackelements but will be moved as others. Never
create transition to all object that have a start > moving group start.
Instead of trying to compute it ourself which might lead to wrong
behaviour when moving between layer.
+ Make sure that when we reset clip children priority (to make space
for effects,) we update the container knowledge of priority offsets
We were computing the priority offset taking the global MIN_NLE_PRIO
(which is a constant == 2 to make space for the mixing elements) instead
of the layer 'track element' relative priority, leading to very big
offsets on layer with a prio > 0. In the end it leaded to effects having
the same priority as the sources which leads to an undefined behaviour
in NLE.
