Unclear status information of backup state while taking backups using TokuBackup

[Shahriyar Rzayev]

While taking backups, from processlist there are some unclear status information such as -> 515% done or even 6047% done:

mysql> set tokudb_backup_dir='/home/tokubackupdir';
Query OK, 0 rows affected (3 min 43.89 sec)

From processlist:

tokudb backup about 515% done: Backup progress 12546179248 bytes, 264 files. Copying file: 1437597696/2243379200 bytes done of /home/tokudb_data_dir/_dbtest_sql_439f_40d_main_326f9_1_1c_B_0.tokudb to /home/tokubackupdir/tokudb_data_dir/_dbtest_sql_439f_40d_main_326f9_1_1c_B_0.tokudb. | set tokudb_backup_dir='/home/tokubackupdir'
