Song Bing 9f81931716 streamsynchronizer: Send GAP event to finish preroll when change state from PLAYING to PAUSED
Wait in the event function when EOS is received until all pads are EOS
and then forward the EOS event from each pads own event function.

Also send a new GAP event for EOS pads from the event function whenever
going from PLAYING->PAUSED by shortly waking up the GCond. This is needed
to allow sinks to pre-roll again, as they did not receive EOS yet because
we blocked that, but also will never get data again.
