Technically this is a lie, since we return a heterogeneous iterator, not
a tuple. But since we don't have a way of typing heterogeneous
iterators, this is the best we can do.

* asyncio: remove BaseChildWatcher from top level
* asyncio.sleep: loop is keyword-only
* asyncio: remove Server from top level
* asyncio: add FastChildWatcher to top level
* asyncio.constants: fix version availability
* asyncio: fix arg name for _wakeup
* asyncio: fix arg name for wrap_future
* asyncio.streams: add Optional to various arguments
It might be possible to further improve some of these with overloads.
* stubtest: fix whitelist

* Use IO[bytes] instead of BytesIO for wave input signatures as it is the (slightly) more general type.
* add missing import

* typing: fix argument names of cast
* typing: use private _Alias class
For py37 and above, this is _GenericAlias, for py36 and below it's
_TypeAlias. I don't think we need to make typing.pyi definitions
correspond more precisely, but we should avoid leaking a
typing.TypeAlias class
- connect_accepted_socket isn't a member of AbstractEventLoop, only
BaseEventLoop
- fix types of arguments with defaults. some of these functions could
have their signatures improved with overloads to reduce false negatives
- correctly mark a positional-only argument
- remove abstractmethod from methods that don't have abstractmethod and
go unimplemented in practice
the `rfile` and `wfile` members are already implemented by
StreamRequestHandler. In addition to them several (undocumented)
class and instance variables exist according to
<https://github.com/python/cpython/blob/master/Lib/socketserver.py#L742>:
- `rbufsize`
- `wbufsize`
- `timeout`
- `disable_nagle_algorithm`
- `packet` and `socket` for datagrams
The already exist with Python 2.7

The Python source (Objects/exceptions.c) explicitly checks for null
pointers before using the filename and lineno members. Some libraries,
e.g. pkg_resources, set filename and lineno to undefined values if
indeed none are appropriate.
It doesn't actually have __call__, it does some descriptor stuff, but
this makes things work. _SingleDispatchCallable has a __call__ too,
which is what this mirrors.
Fixes#3898
