Description:
------------
mysql_field_len() doesn't return the correct field len for 
utf-8 fields. Instead it returns the maximum length mysql 
allows (i.e 3 bytes). That way i can't check user input 
for length sanity.

Reproduce code:
---------------
$fields = mysql_list_fields($link, $table) or msg_error(mysql_error());
$len = mysql_field_len($fields, $i);
echo $len;


Expected result:
----------------
I expect to see the actual length as shown by issuing a 
SHOW FIELDS FROM table query. For example if a field is 
VARHCHAR(8) i expect to see 8, not 24. 

Actual result:
--------------
24
