	Fix #162617.

	* gtk/gtkfilesystemunix.c (STAT_NEEDED_MASK): Take out
	GTK_FILE_INFO_IS_HIDDEN; we don't need to stat() to know this.
	(gtk_file_system_unix_get_folder): Make error reporting more
	accurate.  Don't bail out if we can't read the directory.
	(fill_in_stats): Don't return an error; just assume we don't have
	stat info for this folder's files.
	(fill_in_names): Don't create the hash table for the names if we
	can't open the directory.
	(gtk_file_folder_unix_list_children): Don't emit the
	"finished-loading" signal --- we don't do asynchronous loads, so
	we are always finished loading.
	(gtk_file_folder_unix_get_info): Use helper functions; handle the
	case where we can't stat '/'.
	(get_icon_type_from_path): Don't call fill_in_stats() here; only
	use the info we have.
	(fill_in_mime_type): Don't return an error.  Don't do anything if
	we don't have the stat info.
