This keeps everything in a more consistent order and makes sure that the
base class is already set up completely before we start doing anything.
It also prevents from doing any setup if the base class fails, and
possibly not shutting things down again then.

Otherwise we could set the state of the children to PAUSED already (i.e.
start dataflow) from the composition's task, while the composition
itself is currently chaining up to the parent class' change state
function and did not activate the pads yet. This causes buffers and
events to be discarded, and everything to stop with a not-negotiated
error.

The seek action might currently be handled (in which case it is not in
the actions list and the action lock is not locked), but not actually
handled completely yet (the seqnum is not stored yet).
To prevent this, we remember what the current action is that is being
handled, and also compare to that.

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...

We set TrackElement track type very early when creating effects
so it now uses that information to find TrackElement in clips
by track type.

Computation was not taking into account the fact that the start of
the element being moved could be at the middle of a group and not
necessarily at the start!

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.
Differential Revision: https://phabricator.freedesktop.org/D1280
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.
Differential Revision: https://phabricator.freedesktop.org/D1279
In case effects have been added priorites might become wrong,
but until the timeline is not commited, it does not matter.
Make sure all priorities are correct before commiting compositions
Differential Revision: https://phabricator.freedesktop.org/D1277
Fix all tests as we now have 1 priority inside the layer
dedicated to transitions (basically no source clip will
ever have a priority of 0 inside a layer).
Differential Revision: https://phabricator.freedesktop.org/D1276
And simplify the way we start computing children priority
making min_priority already relative to the clip itself.

By putting uridecodebin into a bin with a ghostpad. Without this,
nlesource tries to get a srcpad too early (before uridecodebin added
one) and everything fails miserably.
This has to be fixed properly in nlesource at some point, by properly
handling dynamically added pads. Currently they can only work if they
are added in states <= READY, which is not the usual case.
