5883 - drop the `ref` keyword

When I created it I was conflating two things:
a) needing to refer to just the start, rather than the whole, and
b) counting indirections.

Both are kinda ill-posed. Now Mu will have just `addr` and `handle` types.
Normal types will translate implicitly to `addr` types, while `handle`
will always require explicit handling.
