Gary Guo 1f989555fe rust: io: add projection macro and methods ...

Add an `io_project!()` macro to allow projection from `Io` to a subview of
it, using the pointer projection mechanism to perform compile-time checks.

For cases where type-casting is required, the `try_cast()` function may be
used where the size and alignment checks are performed at runtime.
