/**
* Declares that a given page uses a favicon with the given URI and
* attempts to fetch and save the icon data by loading the favicon URI
* 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 pages that are already stored in
* the database, like visited pages or bookmarks. For any other URIs, it
* 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
* URI of the favicon to associate with the page.
* @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 aFaviconLoadType
* Set to FAVICON_LOAD_PRIVATE if the favicon is loaded from a private
* browsing window. Set to FAVICON_LOAD_NON_PRIVATE otherwise.
* @param [optional] aCallback
* Once we're done setting and/or fetching the favicon, we invoke this
* callback.
* @param [optional] aLoadingPrincipal
* Principal of the page whose favicon is being set. If this argument
* is omitted, the loadingPrincipal defaults to the nullPrincipal.
* @param [optional] aRequestContextID
* used to inform Necko of how to link the
* favicon request with other requests in the same tab.
*
* @see nsIFaviconDataCallback in nsIFaviconService.idl.

*
* This function does NOT send out notifications that the data has changed.
* Pages using this favicons that are visible in history or bookmarks views
* will keep the old icon until they have been refreshed by other means.
*
* This function tries to optimize the favicon size, if it is bigger
* than a defined limit we will try to convert it to a 16x16 png image.

* Until this time, we won't try to load it again.
