This PR enables an option in
futures-corethat replaces the atomic usage inAtomicWakerwithportable-atomic, and also exposes that flag infutures-util. This intends to make it sofutures-corecan be used on platforms without atomics, like AVR.I look through
futures-utiland didn't see any other usage of atomics that wasn't also locked behind allocation, so I think this is the best I can do here.
