When backing up from a standby server, the backup process will not automatically switch xlog segment. So we must accept a partially transferred xlog file in this case, but rename it into position anyway. In passing, merge the two callbacks for segment end and stop stream into a single callback, since their implementations were close to identical, and rename this callback to reflect that it stops streaming rather than continues it.
