proposed patch

When setcaps is called on gsttee's sinkpad, it will make an iterator over all
the srcpads. While it is iterating, the padlist might change with requestpads
being requested or released, which again will make the iteration abort, and
setcaps fail.

This solution proposes a separate lock to serialize the sinkpad setcaps and the
adding and removing of pads to the element.
