Bug description:FILTER_VALIDATE_URL rejects IPv6 URLs http://[::1]/

Description:
------------
I just came to wonder why the filter extension rejects my IPv6 URLs. For
example this returns false even though it's a valid HTTP url:

    filter_var("http://[::1]:2000/push/thingy",
FILTER_VALIDATE_URL);


I'm somewhat certain that FILTER_VALIDATE_URL actually used
[parse_url](http://php.net/parse_url) behind the scenes to probe for URL
correctness. But parse_url itself works perfectly fine on such addresses:

    Array(
        [scheme] => http
        [host] => [::1]
        [port] => 2000
        [path] => /push/thingy

So there is some limitation in the filter_var wrapper for _VALIDATE_URL.

---

Note that this is a distinct issue to
http://bugs.php.net/bug.php?id=48762&edit=2
which was about
FILTER_VALIDATE_IP addresses only.


Test script:
---------------
<?php

var_dump(filter_var("http://[::1]/path?qs",
FILTER_VALIDATE_URL));

?>

Expected result:
----------------
string(20) "http://[::1]/path?qs"

Actual result:
--------------
bool(false)
