* g_url_new: create a Gurl object from a string
*
* @url_string: The string containing the URL to scan
*
* This routine takes a gchar and parses it as a
* URL of the form:
* protocol://user;AUTH=mech:password@host:port/path
* There is no test on the values. For example,
* "port" can be a string, not only a number!
* The Gurl structure fields are filled with
* the scan results. When a member of the
* general URL can not be found, the corresponding
* Gurl member is NULL.
* Fields filled in the Gurl structure are allocated
* and url_string is not modified.
*
* Return value: a Gurl structure containing the URL items.
