    WL#3776 : Consistent snapshot backup for MVCC
    
    This patch alters the code to allow the use of any storage engine that
    supports consistent snapshots.
    
    The code checks to see if the handler has the method
    start_consistent_snapshot() implemented. If it does, the table is added
    to the driver's list.
