subprocess's communicate(None) closes stdin of the child process, after
sending no (extra) data. Make asyncio variant do the same.
This fixes issues with processes that waits for EOF on stdin before
continuing.

Partially revert changes made in GH-93453.
asyncio.DefaultEventLoopPolicy.get_event_loop() now emits a
DeprecationWarning and creates and sets a new event loop instead of
raising a RuntimeError if there is no current event loop set.

gh-93453: No longer create an event loop in get_event_loop() ( #98440 )
...
asyncio.get_event_loop() now always return either running event loop or
the result of get_event_loop_policy().get_event_loop() call. The latter
should now raise an RuntimeError if no current event loop was set
instead of creating and setting a new event loop.
It affects also a number of asyncio functions and constructors which
call get_event_loop() implicitly: ensure_future(), shield(), gather(),
etc.
DeprecationWarning is no longer emitted if there is no running event loop but
the current event loop was set.

GH-79033: Fix asyncio.Server.wait_closed() ( #98582 )

It was a no-op when used as recommended (after close()).
I had to debug one test (test__sock_sendfile_native_failure) --
the cleanup sequence for the test fixture was botched.
Hopefully that's not a portend of problems in user code --
this has never worked so people may well be doing this wrong. :-(

GH-94597: Deprecate child watcher getters and setters ( #98215 )
...
This is the next step for deprecating child watchers.
Until we've removed the API completely we have to use it, so this PR is mostly suppressing a lot of warnings when using the API internally.
Once the child watcher API is totally removed, the two child watcher implementations we actually use and need (Pidfd and Thread) will be turned into internal helpers.
