Bug Description

If both TokuDB engine and TokuBackup plugin activated on server, then somebody tries to uninstall TokuDB only, TokuBackup plugin will still exist on server:

mysql> select plugin_name, plugin_status from information_schema.plugins where plugin_name like '%toku%';
+---------------+---------------+
| plugin_name | plugin_status |
+---------------+---------------+
| tokudb_backup | ACTIVE |
+---------------+---------------+
1 row in set (0.00 sec)

Resulting in inconsistent situation -> if try to take a backup:

mysql> set tokudb_backup_dir='/home/tokubackupdir';
ERROR 1193 (HY000): Unknown system variable 'tokudb_data_dir'

So TokuBackup should be removed(if it is activated) with TokuDB uninstall process.

Now when you do --enable-backup it automatically means --enable too, also when you use --disable to uninstall tokudb it automatically means --disable-backup also. But you can install only tokudb without backup and uninstall only backup without touching tokudb.
