Calls thunar_vfs_init() and thunar_vfs_shutdown(). Those calls can be removed.

Use a GFile instead of a ThunarVfsPath when creating the file icon manager. Pass the GFile to the manager object instead of the ThunarVfsPath.

Use a GFile instead of the ThunarVfsPath for the target_path struct member.

Make xfdesktop_file_utils_file_icon_list_to_path_list() return a list of GFile objects. Reuse thunar_g_file_list_to_string() instead of using thunar_vfs_path_list_to_string(). Use g_list_foreach() and g_list_free() instead of thunar_vfs_path_list_free().

There's no need for cancelling jobs if we don't use jobs anymore. Instead we'll use the new D-Bus methods that have been added to Thunar. When using those we can just fire and forget.

We don't need the file info here. Just launch the file using Thunar's Launch() D-Bus method. Add an interface method get_file and make it return a GFile. Use this GFile to compute the URI to be passed to Launch().

Make the interface method peek_info return a GFileInfo.
