Currently, `Io` is implemented on owned I/O objects (e.g. `Bar`). This is
going to change with I/O projections, as then `Io` needs to work both for
owned objects and views of them. Views are themselves reference-like
(however they obviously cannot be references, because they belong to a
different address space).
To facilitate the change, change `Io` to be implemented on reference types
for the owned I/O objects, and make methods take `self` instead of `&self`.
When I/O views are implemented, we can then naturally implement `Io` for
these objects.
