      Bug#39063 - Online Backup: Backup behavior changes with the case used for the database name
            
      Before, the database list for BACKUP was case sensitive. This caused problems in case insensitive servers because database 'X' and 'x' is considered the same database while backup would fail if the wrong case was used.
            
      With this patch, the database names are converted to lower case when BACKUP is executed on a case insensitive server.

    Reflect change to si_object#get_database_stub signature.
  sql/si_objects.cc
    Normalize the database name before creating a database object on servers with case insensitive database names.

    get_database_stub signature changed: THD added as parameter
  sql/sql_lex.cc
    Remove check of unique database name for BACKUP command. This check is now performed in backup_info.cc.
