Module tor_async_utils::oneshot

Thin veneer over futures::channel::oneshot to fix use with select!

A bare futures::channel::oneshot::Receiver doesn’t work properly with futures::select!, because it has a broken FusedFuture implementation. (See futures-rs ticket #2455.)

Wrapping it up in a future::Fuse works around this, with a minor performance penalty.

Limitations

The API of this Receiver is rather more limited. For example, it lacks .try_recv().
