Description: This PR follows up on the issue 26969. It is meant to ensure that asyncio.get_event_loop returns the running loop when called in a coroutine (or loop callbacks). This could simplify all the coroutines that includes a loop optional argument by removing it. This is done by modifying the interface of AbstractEventLoopPolicy: get/set_event_loop is renamed to get/set_default_loop get/set_running_loop is added get_event_loop now uses the running loop if available, and the default loop otherwise BaseEventLoopPolicy is updated, and adds a few features: it does not allow to set a running loop if another one is already set it issues warnings if the running loop doesn't correspond to the default loop A context manager is also added to AbstractEventLoopPolicy and AbstractEventLoop to set and clear the running loop in a safe manner. This might help for other event loop implementations.
