Mathieu Duponchelle 25383eaa5c aggregator: refactor flushing logic 
Instead of tracking "pending_flush_*" on the pads and the
aggregator, we now simply track the last seqnum for flush start
and flush stop events on the pads, and use it to determine whether
we should enter or exit our flushing state.
