Made a theorical libgstplay which refs/unrefs elements before putting them in AsyncQueue.
Original commit message from CVS: Made a theorical libgstplay which refs/unrefs elements before putting them in AsyncQueue. Added a "pipeline_error" signal which will later allow the player and apps to detect that pipeline was unable to play and why... This version is NOT STABLE AT ALL. it will need fixes in core but i commit it as is so that we fix those problems
