2.0.0 - update, remove some non-CPython API
What's Changed
- Incorporate upstream changes, including fixing state of cur_task and other things.
- Remove ThreadSafeFlag: it's in MicroPython, but not in CPython. If we need something like this, put it back later.
- Add get_running_loop()
- Use await instead of yield.
- Restore gather to be async.
- Make comments be more CircuitPython-centric.
- Add CIRCUITPY-CHANGE annotations to note code changes from MicroPython, to ease later merges.
