There are a couple other py39 changes to be made in asyncio, but I'm
trying to avoid merge issues with whitelists / Windows for now.

* 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

- 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 _types module can house any common type defintions used throughout
the rest of typeshed to keep defintions in sync.
First candidate is file descriptors where anything with `fileno()`
method is accepted. There were several different implementations in
various files that can be unified.
The documentation states:
* datagram_received: "data is a bytes object containing the incoming data."
* pipe_data_received: "data is a non-empty bytes object containing the received data."
Fix errors discovered by running typeshed check on Windows. This is a temporary fix for #3446 (in long term we should figure out why these were not caught by typeshed CI).
I also remove an outdated comment while I am at it.
* Add explicit ssl_handshake_timeout arguments to open_connection and start_server
* Add context arguments to call methods
* Accept PathLike for create_unix_* paths
* Add TimerHandle.when()
Add missing version check
* AbstractServer is now an async context manager
* Add happy_eyeballs_delay and interleave arguments to create_connection
* Re-export asyncio.windows_events from asyncio
* Add name argument to Task constructor
* Add Task.get_coro()
* import and other fixes
* Fix return type of get_coro()
* Add public missing asyncio stubs for windows and proactor files, and any necessary private return/argument types.
* Add methods to BaseProactorEventLoop that mypy is complaining about, with note about status at runtime
* Add asyncio constants file
* Add os.add_dll_directory()
* Add memfd_create() and flags
* Add type annotation to flags
* Add stat_result.st_reparse_tag and flags
* Add ncurses_version
* Add Path.link_to()
* Add Picker.reducer_override()
* Add plistlib.UID
* Add has_dualstack_ipv6() and create_server()
* Add shlex.join()
* Add SSL methods and fields
* Add Python 3.8 statistics functions and classes
* Remove obsolete sys.subversion
* Add sys.unraisablehook
* Add threading.excepthook
* Add get_native_id() and Thread.native_id
* Add Python 3.8 tkinter methods
* Add CLOCK_UPTIME_RAW
* Add SupportsIndex
* Add typing.get_origin() and get_args()
* Add unicodedata.is_normalized
* Add unittest.mock.AsyncMock
Currently this is just an alias for Any like Mock and MagicMock. All of
these classes should probably be sub-classing Any and add their own
methods. See also #3224.
* Add unittest cleanup methods
* Add IsolatedAsyncioTestCase
* Add ElementTree.canonicalize() and C14NWriterTarget
* cProfile.Profile can be used as a context manager
* Add asyncio task name handling
* mmap.flush() now always returns None
* Add posonlyargcount to CodeType
The stub for asyncio.as_completed declared it as taking a Sequence of
Futures. This was unnecessarily strict.
Just like asyncio.wait, asyncio.as_completed can be declared to take
an Iterable of Futures instead. Both these functions iterate over
their argument only once to store its items in a set, so an Iterable
is sufficiently strict. This has been true since the initial
implementation of the functions.
