syncbase/vsync: eager sync watcher

Make the sync watcher more eager to consume updates from databases by
continuing to process updates as long at it finds some.  Remain fair by
doing a round-robin across databases, taking one batch update from each
database at a time.  Continue doing passes across the databases until
all of them have no further updates pending.
