96672825d5 gnloperation: Totally clear operations when removing emptying current_bin 
Removing linked childre leads to weird behaviour, we want to make sure
that all elements are totally clean when they are out the current bin.

054569cce7 composition: Implement the logic to PAUSE the task while executing actions 
We need to wait for the pipeline update to be actually finished before we can start another
action. That means that we pause the task until one buffer from the new stack is
outputed.

7de8b9c16c composition: Rework the seqnum logic to avoid races when setting the new stack seqnum 
When we were seeking the same stack without a logic that gurantees that we actually
saw the seek with the new seqnum set, we could have ended up with an EOS set with
the right seqnum even if it was actually not the case.

f0c5f87284 compositition: Check last stack in the children thread 
Avoiding to take the OBJECT_LOCK when recieving EOS. The computation is
based on the GstEvent.seqnum to make sure that the EOS we receive
corresponds to the right sequence.

In that patch we tweak seqnums so that they are correctly computed
avoiding to depend on all elements to do it properly as it might pretty
much not be the case!
