We were only concidering that we should let the group handle moving
transitions when changing transitions but in fact as soon as a
transition is happenning between two clips that are in a same group
the group properly handles moving the transition, so let the
group do its job.

GESLayer is now responsible for setting clips priorites. Also
GESClip top effects priorities are now set by the
ges_clip_set_top_effect_index method, the user should never call
ges_timeline_element_set_priority as it will anyway be overriden
by GES itself.

All operations should have higher priorites and sources should be
on top of those. We now first set the operations priorities in
a first pass and then stack sources on top of those.

In case effects have been added priorites might become wrong,
but until the timeline is not commited, it does not matter.

Those are implemented with the exact same API at the GESTimelineElement
level now, and user of those APIs with high level languages will get the
exact same API.
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.
This is the only header which shall be included by user. Otherwise some
language using gir to generate binding, e.g Vala, will includes all
headers files in alphabetical order which causes compilation errors due
to incomplete type.

Debugging must be configuring first (before any parsing), and then

Fixes issues with debugging categories not being available at the

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.
