Allocate a new flush start event. The flush start event can be send
upstream and downstream and travels out-of-bounds with the dataflow.
It marks pads as being in a WRONG_STATE to process more data.
Elements unlock and blocking functions and exit their streaming functions
as fast as possible.
This event is typically generated after a seek to minimize the latency
after the seek.
