Add the `Opaque` type, which is meant to be used with FFI objects
that are never interpreted by Rust code, e.g.:
struct Waiter {
completion: Opaque<bindings::completion>,
next: *mut Waiter,
}
It has the advantage that the objects don't have to be
zero-initialised before calling their init functions, making
the code performance closer to C.

rust: types: add `Either` type2022-12-04T00:59:16ZWedson Almeida Filhowedsonaf@gmail.com2022-11-10T16:41:39Zurn:sha1:ba20915bae49024dab6ee582abdd4cd8944a3e55
Introduce the new `types` module of the `kernel` crate with
`Either` as its first type.
`Either<L, R>` is a sum type that always holds either a value
of type `L` (`Left` variant) or `R` (`Right` variant).
For instance:
struct Executor {
queue: Either<BoxedQueue, &'static Queue>,
}
