[FLINK-1775] BarrierBuffer fix to avoid end of stream deadlock
This fixes several corner-cases in the barrier buffer logic.
Still two problems remain:
- If the StreamRecordWriter is active (a thread is running to flush the
ouputs every so many milliseconds)
- On travis the RecordWriters seem to deadlock at the sources for some
reason on broadcastEvent calls. (I cannot reproduce this locally)
