Aaron Schulz 5c8ef13306 Add WRITE_SYNC flag to BagOStuff::set()/merge()
* This blocks on writing to all replicas
  and returns false if any failed.
* This is useful if ChronologyProtector is to work across
  domains by having the writes go everywhere so that later
  reads will see them (and be local at the same time).
* Redundant doc comments were also removed.
