Bug description:  Values set with php_admin_* in httpd.conf can be overwritten with ini_set()

Description:
------------
When I set a value inside the httpd.conf with php_admin_value or
php_admin_flag that is INI_ALL or INI_PERDIR it can be overwritten at
runtime using ini_set()

I don't think this should be possible. But the documentation on this
problem doesn't assure me if this is a bug or a feature!

Reproduce code:
---------------
/etc/apache2/httpd.conf :
php_admin_value memory_limit 3145728


iniset_test.php :
<?php

$old = ini_set("memory_limit", 20971520);

echo "old: ".$old;

$new = ini_get("memory_limit");

echo "<br>new: ".$new;

?>

Expected result:
----------------
The result is the following:
old: 3145728
new: 3145728 

Actual result:
--------------
The result is the following:
old: 3145728
new: 20971520
