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!
