This is mostly a 1:1 replacement, except for the fact that the same_channel api is missing from async_channel. So I replaced it with some ugly code that uses the fact that a async_channel Sender or Receiver is just an Arc<Channel>. To be removed if/when smol-rs/async-channel#98 is merged, but until then I think it is fine.

## Description This is mostly a 1:1 replacement, except for the fact that the same_channel api is missing from async_channel. So I replaced it with some ugly code that uses the fact that a async_channel Sender or Receiver is just an Arc<Channel>. To be removed if/when smol-rs/async-channel#98 is merged, but until then I think it is fine. ## Breaking Changes None ## Notes & open questions Note: we can not use tokio::sync::mpsc::Channel for the actor because we can't control from which thread Drop is called. Note: some streams were Unpin before, but it was not explicit. Now I added Unpin explicitly (and boxed the stream to make it true). Not sure if the version check would catch this, pretty sure that not. But taking away Unpin would have been a breaking change. ## Change checklist - [ ] Self-review. - [ ] Documentation updates following the [style guide](https://rust-lang.github.io/rfcs/1574-more-api-documentation-conventions.html#appendix-a-full-conventions-text), if relevant. - [ ] Tests if relevant. - [ ] All breaking changes documented.

I am porting some code from flume to async_channel, and this is one fn that I am sorely missing.
The implementation seems to be quite simple.
