Make pad block call the callback as soon as the pad is not in use. This makes it possible to make sure that when the callback is called, no activity is happening on the pad and that no activity will ever happen until the pad is unblocked again. This makes pad blocking work when there is no dataflow or after EOS and greatly helps dynamic pipelines. Move the probe handling right where we wait on the pad block. The two are related but not the same and the probe can eventually influence the pad blocking as we'll se later. Fix up some broken unit tests or tests that fail with the new behaviour.
