      Bug#13344643:Format function in view looses locale information
      
      Problem description:
      When a view is created using function FORMAT and if FORMAT function uses locale
      option,definition of view saved into server doesn't contain that locale information,
      Ex:
      create  table test2 (bb decimal (10,2));
      insert into test2 values (10.32),(10009.2),(12345678.21);
      create view test3 as select format(bb,1,'sk_SK') as cc from test2;
      select * from test3;
      +--------------+
      | cc           |
      +--------------+
      | 10.3         |
      | 10,009.2     |
      | 12,345,678.2 |
      +--------------+
      3 rows in set (0.02 sec)
      
      show create view test3
                      View: test3
               Create View: CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost`
      SQL SECURITY DEFINER VIEW `test3` AS select format(`test2`.`bb`,1) AS `cc`
      from `test2`
      character_set_client: latin1
      collation_connection: latin1_swedish_ci
      1 row in set (0.02 sec)
      
      Problem Analysis:
      The function Item_func_format::print() which prints the query string to create
      the view does not print the third argument (i.e the locale information). Hence
       view is created without locale information. 
      
      Problem Solution:
      If argument count is more than 2 we now print the third argument onto the query string.
      
      Files changed:
      sql/item_strfunc.cc
      Function call changes: Item_func_format::print()
      mysql-test/t/select.test
      Added test case to test the bug
      mysql-test/r/select.result
