Bug #33406 ndb_restore -e restores epoch with wrong (big) value from old backups

Description:
ndb_restore -e restores to big value into apply_status if restore done from old (pre micro GCP) version, e.g. mysql-5.0/1 or CGE-6.1

How to repeat:

Suggested fix:
workaround in current CGE versions is to shift value of epoch down 32 bits to get correct value

  Bug #33406  	ndb_restore -e restores epoch with wrong (big) value from old backups

Documented in the 5.1.23-ndb-6.3.8 changelog as follows:

      
        ndb_restore -e restored excessively large
        values to the ndb_apply_status table's
        epoch column when restoring to a MySQL
        Cluster version supporting Micro-GCPs from an older version that
        did not support these.        
      
      
      
        A workaround when restoring to MCCGE releases
        supporting micro-GCPs previous to MySQL 5.1.23-ndb-6.3.8 is to
        perform a 32-bit shift on the epoch column
        values to reduce them to their proper size.

Also documented for 5.1.23-ndb-6.2.11.

Pushed into 6.0.5-alpha
