695: Simplify Channel. r=Dirbaio a=Dirbaio
- Allow initializing in a static, without Forever.
- Remove ability to close, since in embedded enviromnents channels usually live forever and don't get closed.
- Remove MPSC restriction, it's MPMC now. Rename "mpsc" to "channel".
- `Sender` and `Receiver` are still available if you want to enforce a piece of code only has send/receive access, but are optional: you can send/receive directly into the Channel if you want.

Due to not requiring Unpin, it's not really possible to call it
after having polled it, you can only call it right after constructing it,
so in practice it's not very useful.
693: no_std version of `futures::future::select_all` r=Dirbaio a=alexmoon
Here's a no-std compatible version of `select_all`. It's not quite as useful as the original because it requires an array of Unpin futures to be pre-constructed instead of taking an iterator (which could return `Pin<Box<_>>` in `std`). And, of course, you don't get a `Vec` of the unfinished futures returned at completion. Still, I think it's cleaner than a long cons of select calls.
I'll leave it up to you whether this is sufficiently general purpose to include in Embassy or not.
