Based on a comment from @asvetlov #15735 (comment), this removes the provisional note for ``asyncio.run()`` in the documentation.

Typically, the second positional argument for ``seek()`` is *whence*. That is the POSIX standard name (http://man7.org/linux/man-pages/man3/lseek.3p.html) and the name listed in the documentation for ``io`` module (https://docs.python.org/3/library/io.html#io.IOBase.seek). 

The tutorial for IO is the only location where the second positional argument for ``seek()`` is referred to as *from_what*. I suspect this was created at an early point in Python's history, and was never updated (as this section predates the GitHub repository):

```
$ git grep "from_what"
Doc/tutorial/inputoutput.rst:To change the file object's position, use ``f.seek(offset, from_what)``.  The position is computed
Doc/tutorial/inputoutput.rst:the *from_what* argument.  A *from_what* value of 0 measures from the beginning
Doc/tutorial/inputoutput.rst:the reference point.  *from_what* can be omitted and defaults to 0, using the
```

For consistency, I am suggesting that the tutorial be updated to use the same argument name as the IO documentation and POSIX standard for ``seek()``, particularly since this is the only location where *from_what* is being used.

Note: In the POSIX standard, *whence* is technically the third positional argument, but the first argument *fildes* (file descriptor) is implicit in Python.

Move `threaded_import_hangers`, a dependency of `test_threaded_import`, to the directory `test_importlib/`. Also update the import references for `threaded_import_hangers` in `test_threaded_import`.

Replacing the deprecated method "random.choose" to "random.choice" was technically not part of the original issue. However, it was discussed in the talk page and involved one of the files being moved. I assumed this was too minor to justify the creation of a separate issue. 

Also, I added my name to the contributors list in Misc/ACKS. This will be my third PR to cpython, forgot to do it in the previous ones.

Also renamed the file to "test_pkg_import.py" to better follow the naming convention. Component of issue 19696.

* Docs: Improved phrasing 

Removed usage of second person pronouns in the section and made the assumption of "uneasiness" in code style transition more neutral.
