   * Declares that a given page uses a favicon with the given URI and

   * through an async network request.
   *
   * If the icon data already exists, we won't try to reload the icon unless
   * aForceReload is true.  Similarly, if the icon is in the failed favicon
   * cache we won't do anything unless aForceReload is true, in which case
   * we'll try to reload the favicon.
   *
   * This function will only save favicons for "good" URIs, as defined by what
   * gets added to history or is a bookmark.  For "bad" URIs, this function
   * will succeed but do nothing.  This function will also ignore the error
   * page favicon URI (see FAVICON_ERRORPAGE_URL below).
   *
   * Icons that fail to load will automatically be added to the failed favicon
   * cache, and this function will not save favicons for non-bookmarked URIs
   * when history is disabled.
   *
   * @note This function is identical to
   *       nsIFaviconService::setAndLoadFaviconForPage.
   *
   * @param aPageURI
   *        URI of the page whose favicon is being set.
   * @param aFaviconURI

   * @param aForceReload
   *        If aForceReload is false, we try to reload the favicon only if we
   *        don't have it or it has expired from the cache.  Setting
   *        aForceReload to true causes us to reload the favicon even if we
   *        have a usable copy.
   * @param aCallback
   *        Once we're done setting and/or fetching the favicon, we invoke this
   *        callback.

   * @see nsIFaviconDataCallback in nsIFaviconService.idl.
