For a quick, clean solution that doesn't require you to name columns, you can use a prepared statement as described here: https://stackoverflow.com/a/23964285/292677

If you need a complex solution so you can do this often, you can use this procedure:

DELIMITER $$

CREATE PROCEDURE `duplicateRows`(_schemaName text, _tableName text, _whereClause text, _omitColumns text)
SQL SECURITY INVOKER
BEGIN
  SELECT IF(TRIM(_omitColumns) <> '', CONCAT('id', ',', TRIM(_omitColumns)), 'id') INTO @omitColumns;

  SELECT GROUP_CONCAT(COLUMN_NAME) FROM information_schema.columns 
  WHERE table_schema = _schemaName AND table_name = _tableName AND FIND_IN_SET(COLUMN_NAME,@omitColumns) = 0 ORDER BY ORDINAL_POSITION INTO @columns;

  SET @sql = CONCAT('INSERT INTO ', _tableName, '(', @columns, ')',
  'SELECT ', @columns, 
  ' FROM ', _schemaName, '.', _tableName, ' ',  _whereClause);

  PREPARE stmt1 FROM @sql;
  EXECUTE stmt1;
END

You can run it with:

CALL duplicateRows('database', 'table', 'WHERE condition = optional', 'omit_columns_optional');

Examples

duplicateRows('acl', 'users', 'WHERE id = 200'); -- will duplicate the row for the user with id 200
duplicateRows('acl', 'users', 'WHERE id = 200', 'created_ts'); -- same as above but will not copy the created_ts column value    
duplicateRows('acl', 'users', 'WHERE id = 200', 'created_ts,updated_ts'); -- same as above but also omits the updated_ts column
duplicateRows('acl', 'users'); -- will duplicate all records in the table

DISCLAIMER: This solution is only for someone who will be repeatedly duplicating rows in many tables, often. It could be dangerous in the hands of a rogue user.
