Marko Mäkelä 92f87f2cf0 Cleanup: Remove changed_pages_bitmap
The innodb_changed_pages plugin only was part of XtraDB, never InnoDB.
It would be useful for incremental backups.
We will remove the code from mariadb-backup for now, because it cannot
serve any useful purpose until the server part has been implemented.
