Description:
If a user runs an incremental backup and the option --backup-and-apply-log is also given then the incremental backup will succeed. Afterwards applying the log is attempted but fails. However, apply-log should never have been attempted in the first place because it is not possible to do apply-log to a full backup since that option is not available.

How to repeat:
Run an incremental backup using both the option --incremental and --backup-and-apply-log

Assigning Thava as a reviewer and I think one review is sufficient.

If there is some new restriction or a restriction lifted by this patch, please supply the details to better judge if something needs to be mentioned in the doc.

--backup-and-apply-log takes the full backup and does  --apply-log on 
that backup implicitly. mysqlbackup has all the resources to do a  apply-log 
 on the full backup.

However, with --backup-and-apply-log, the resources to apply-log
 for incremental backup is not available for  mysqlbackup 
(ex:INCREMENTAL_BACKUP.CNF).

So, --incremental (for incremental backup) should not be allowed for 
--backup-and-apply-log. 

We can have a note in the documentation, that --backup-and-apply-log is only for full backup.
