b1240217bd Remove Portal. Fixes #32
Portal is very niche, I've only ever used it in `nrf-softdevice` and in a very particular case:
sending event raw-pointers across tasks but "synchronously", because the destination task must process
it now, so it's not deallocated. For most usecases, Signal or channels is enough.

It's unclear to me whether it can be made ub-free. It has problems with reentrancy. It's also not leak-safe, which is quite annoying.

So, remove it for now. We can always add it back later.

332bc44b8c Expose SendFuture and RecvFuture types
Having these types available makes it easier to store futures for later
use as the named types can be embedded in other types at compile time.

1b9d5e5071 Multi Producer Single Consumer channel
An MPSC inspired by Tokio and Crossbeam. The MPSC is designed to support both single and multi core processors, with only single core implemented at this time. The allocation of the channel’s buffer is inspired by the const generic parameters that Heapless provides.
