Done. Please see the attached patch.
Design:
* pg_stop_backup writes the backup-end xlog record which contains
the backup starting point.
* In archive recovery, the startup process doesn't mark the database
as consistent until it has read the backup-end record.
* A backup history file is still created as in the past, but is never
used.
