PHP fallback function http_build_url()

For servers without pecl_http package installed.

See http://php.net/manual/en/function.http-build-url.php

Based on the original C code from pecl_http-1.7.6
http://git.php.net/?p=pecl/http/pecl_http.git;a=blob;f=php_http_url_api.h;h=940db8e61e68e1a544896a691079ad33c5b633ff;hb=b84c1c206944586e218e57a864ab9671194a10cf

Usage:
Place this file on a suitable directory of your PHP system.
Inside a common bootstrap file within your system insert the following piece of code:

if (!function_exists('http_build_str') || !function_exists('http_build_url')) {
    require dirname(__FILE__).'/write/your/relative/path/here/http_build_url.php';
}

After that, the functions http_build_url() and http_build_str() would be callable.
A quick test:

echo http_build_url();

For testing this fallback implementation, place the file http_build_url_test.php on the web-server too, and open it with a browser. Don't forget to remove it when it is no longer needed.

Live test demo: http://iridadesign.com/starter-public-edition-4/www/non-mvc/http_build_url_test.php

An important note: Don't use host autodetection (or more generally base url autodetection) implemented by this function, it relies first on $_SERVER['HTTP_HOST'].
