Bug #21466 INET_ATON() returns signed value, not unsigned

Description:
INET_ATON() appears to return a signed BIGINT value,
whereas IP numbers are better represented as unsigned
values.

How to repeat:
mysql> create table t select inet_aton('127.0.0.1') as i;
Query OK, 1 row affected (0.07 sec)
Records: 1  Duplicates: 0  Warnings: 0

mysql> show create table t;
+-------+-----------------------------------------------------------------------------------------+
| Table | Create Table                                                                            |
+-------+-----------------------------------------------------------------------------------------+
| t     | CREATE TABLE `t` (
  `i` bigint(21) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1 | 
+-------+-----------------------------------------------------------------------------------------+
1 row in set (0.01 sec)

verified on the API level, too:

<?php

mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());

$result = mysql_query("select inet_aton('129.0.0.1') as i, CAST(inet_aton('129.0.0.1') as unsigned) as j") or die(mysql_error());
   $meta = mysql_fetch_field($result, 0);
   echo "
name:        $meta->name
type:        $meta->type
unsigned:    $meta->unsigned
";

   $meta = mysql_fetch_field($result, 1);
   echo "
name:        $meta->name
type:        $meta->type
unsigned:    $meta->unsigned
";
?>

name:        i
type:        int
unsigned:    0

name:        j
type:        int
unsigned:    1

Fixed in mysql-5.1-new-maint

Created new test (func_inetaton) all tests pass.
