* Crea un URL completo ad una pagina del portale a partire dalle

* In questa implementazione, l'URL è costruito come concatenazione dei
* seguenti elementi:
*
* - parametro di configurazione PAR_APPL_BASE_URL, che rappresenta l'URL
* base della web application così come viene visto dall'esterno; deve
* comprendere la stringa "http://" e deve terminare con "/";
* - codice della lingua impostata nell'oggetto pageUrl, oppure la lingua
* corrente, oppure la lingua di default;
* - se il parametro "urlStyle" è settato a "classic", codice della pagina
* corrente impostata nell'oggetto pageUrl seguito dal suffisso ".page",
* altrimenti, se il parametro "urlStyle" è settato a "breadcrumbs",
* "/pages/" seguito dal'insieme del codici pagina dalla root alla pagina
* corrente separati da "/";
* - eventuale query string se sull'oggetto pageUrl sono stati impostati
* parametri.
*
*
* @param pageUrl L'oggetto contenente le informazioni da tradurre in URL.
* @param reqCtx Il contesto della richiesta.
* @return La Stringa contenente l'URL.
