Chaithra Gopalareddy 73e69d0f8c 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
Result of the test case appended here
