Bug description:  parse_url is *slow*

parse_url() is over 30 times slower than a PHP code doing the same thing
with preg_match.  Check this out:

parse_url.php:

<?php

for ($i = 0; $i < 50000; $i++) {
    $fullurl = "http://www.example.com:80/blah/bing?foo=bar&gazonk=true";
    $url = parse_url($fullurl);
}

?>

$ time php parse_url.php 

real	1m41.777s
user	1m35.770s
sys	0m0.200s


preg_match.php:

<?php

for ($i = 0; $i < 50000; $i++) {
    $fullurl = "http://www.example.com:80/blah/bing?foo=bar&gazonk=true";
   
preg_match('!^(([^:/?#]+):)?(//([^/:?#]*)(:(\d+))?)?([^?#]*)(\\?([^#]*))?(#(.*))?!',
$fullurl, $matches);
   
list(,,$url['scheme'],,$url['host'],,$url['port'],$url['path'],,$url['query'])
= $matches;
}

?>

$ time php preg_match.php

real	0m2.950s
user	0m2.940s
sys	0m0.000s
