ha_innobase::prepare_inplace_alter_table(): Unless the table is being rebuilt, determine the maximum column length based on the current ROW_FORMAT of the table. When TABLE_SHARE (and the .frm file) contains no explicit ROW_FORMAT, InnoDB table creation or rebuild will use innodb_default_row_format. Based on mysql/mysql-server@3287d33acd
