queue: add unit test Make a downstream element return an error after upstream has already put all data into queue (including EOS). As such, upstream will not be around to pick up the error, so it is up to queue to act appropriately. See #589991. Note there may be downstream fatal errors (e.g. negotiation) that do not warrant an error message already having been posted.

pad: further improve probes and pad blocking Keep track of installed number of probes to shortcut emission. Allow NULL callbacks, this is useful for blocking probes. Improve probe selection based on the mask, an empty mask for the data or the scheduling flags equals that all probes match. Add some more debug info. Don't check the flushing flag in the probe callback handler, this needs to be done before calling the handler. Fix blocking probes. Fix unit tests

pad: rework pad probes Make a separate cookie to detect chancges in the list of probes and keeping track of what hooks have been invoked yet. Remove the requirement to have probes on srcpads in push mode and sinkpads in pull mode. Add some more debug. Keep track of what callbacks got executed. If no callback is called and we are a blocking pad, let the item pass. This allows you to block pads on selected items only. Explicitly have an UPSTREAM and DOWNSTREAM PadProbeType. This allows you to only block the pad on upstream or downstream items. Add convenience macros to only block on downstream/upstream items.
