Bug #6911 resultset metadata always return client character set

Description:
When retrieving resultset metadata, charsetnr in fields always contain the client character set 
instead of the character set for the column in the database. 
 
This behaviour makes it impossible to determine the correct columnDisplaySize (a function which 
is used in most of the MySQL connectors). 
 
 
Output from test.c 
 
1st) with client character set utf8 
Charsetnr: 33 
CharsetName: utf8 
ColumnDisplaySize: 50 
 
2nd) with client character set latin1 
Charsetnr: 8 
CharsetName: latin1 
ColumnDisplaySize: 150 

How to repeat:
#include <my_global.h> 
#include <m_ctype.h> 
#include <mysql.h> 
#include <stdio.h> 
 
CHARSET_INFO *get_charset(uint, myf); 
 
main() { 
	MYSQL		*mysql; 
	MYSQL_RES	*result; 
	CHARSET_INFO *cs; 
 
	mysql = mysql_init(NULL); 
 
	mysql_real_connect(mysql, "localhost", "root", "", "test", 0, NULL, 0); 
 
	mysql_query(mysql, "DROP TABLE IF EXISTS t3"); 
	mysql_query(mysql, "CREATE TABLE t3 (a varchar(50) character set utf8)"); 
 
	mysql_query(mysql, "SELECT a FROM t3 WHERE 0=1"); 
	result = mysql_store_result(mysql); 
 
	cs = get_charset(result->fields[0].charsetnr, 0); 
 
	printf("Charsetnr: %d\n", result->fields[0].charsetnr); 
	printf("CharsetName: %s\n", cs->csname); 
	printf("ColumnDisplaySize: %d\n", result->fields[0].length / cs->mbmaxlen); 
 
	mysql_free_result(result); 
	mysql_close(mysql);     
}
