fb4e155696 utils/asyn: Replace nest_asyncio with greenlet
Provide an implementation of re-entrant asyncio.run() that is less
brittle than what greenback provides (e.g. no use of ctypes to poke
extension types).

The general idea of the implementation consists in treating the executed
coroutine as a generator, then turning that generator into a generator
implemented using greenlet. This allows a nested function to make the
top-level parent yield values on its behalf, as if every call was
annotated with "yield from".

796b9fc1ef utils/asyn: Fix memoized_method.__set_name__

property.

fefdf29ed8 utils/asyn: Add memoize_method() decorator
Add a memoize_method decorator that works for async methods. It will not
leak memory since the memoization cache is held in the instance
__dict__, and it does not rely on hacks to hash unhashable data.
