Serializes a GIcon into a GVariant. An equivalent GIcon can be retrieved
back by calling g_icon_deserialize() on the returned value.
As serialization will avoid using raw icon data when possible, it only
makes sense to transfer the GVariant between processes on the same machine,
(as opposed to over the network), and within the same file system namespace.
