Add PyConfig_Get(), PyConfig_GetInt(), PyConfig_Set() and
PyConfig_Names() functions to get and set the current runtime Python
configuration.
Add visibility and "sys spec" to config and preconfig specifications.
_PyConfig_AsDict() now converts PyConfig.xoptions as a dictionary.

Remove *ignore* and *on_error* arguments from `pathlib.Path.copy[_into]()`,
because these arguments are under-designed. Specifically:
- *ignore* is appropriated from `shutil.copytree()`, but it's not clear
how it should apply when the user copies a non-directory. We've changed
the callback signature from the `shutil` version, but I'm not confident
the new signature is as good as it can be.
- *on_error* is a generalisation of `shutil.copytree()`'s error handling,
which is to accumulate exceptions and raise a single `shutil.Error` at
the end. It's not obvious which solution is better.
Additionally, this arguments may be challenging to implement in future user
subclasses of `PathBase`, which might utilise a native recursive copying
method.
Per feedback from Paul Moore on GH-123158, it's better to defer making
`Path.delete()` public than ship it with under-designed error handling
capabilities.
We leave a remnant `_delete()` method, which is used by `move()`. Any
functionality not needed by `move()` is deleted.
These two methods accept an *existing* directory path, onto which we join
the source path's base name to form the final target path.
A possible alternative implementation is to check for directories in
`copy()` and `move()` and adjust the target path, which is done in several
`shutil` functions. This behaviour is helpful in a shell context, but
less so in a stored program that explicitly specifies destinations. For
example, a user that calls `Path('foo.py').copy('bar.py')` might not
imagine that `bar.py/foo.py` would be created, but under the alternative
implementation this will happen if `bar.py` is an existing directory.
Add a `Path.move()` method that moves a file or directory tree, and returns a new `Path` instance pointing to the target.
This method is similar to `shutil.move()`, except that it doesn't accept a *copy_function* argument, and it doesn't check whether the destination is an existing directory.

Rename `pathlib.Path.copy()` to `_copy_file()` (i.e. make it private.)
Rename `pathlib.Path.copytree()` to `copy()`, and add support for copying
non-directories. This simplifies the interface for users, and nicely
complements the upcoming `move()` and `delete()` methods (which will also
accept any type of file.)

In the documentation of `PosixPath` and `WindowsPath`, and their `Pure*`
equivalents, use example paths with multiple non-anchor parts.

Return -1 and set an exception on error; return 0 if the iterator is
exhausted, and return 1 if the next item was fetched successfully.
Prefer this API to PyIter_Next(), which requires the caller to use
PyErr_Occurred() to differentiate between iterator exhaustion and errors.

Rename `pathlib.Path.rmtree()` to `delete()`, and add support for deleting
non-directories. This simplifies the interface for users, and nicely
complements the upcoming `move()` and `copy()` methods (which will also
accept any type of file.)
This flag was added as an escape hatch in gh-91401 and backported to
Python 3.10. The flag broke at some point between its addition and now.
As there is currently no publicly known environments that require this,
remove it rather than work on fixing it.
This leaves the flag in the subprocess module to not break code which
may have used / checked the flag itself.

## Encode header parts that contain newlines
Per RFC 2047:
> [...] these encoding schemes allow the
> encoding of arbitrary octet values, mail readers that implement this
> decoding should also ensure that display of the decoded data on the
> recipient's terminal will not cause unwanted side-effects
It seems that the "quoted-word" scheme is a valid way to include
a newline character in a header value, just like we already allow
undecodable bytes or control characters.
They do need to be properly quoted when serialized to text, though.
## Verify that email headers are well-formed
This should fail for custom fold() implementations that aren't careful
about newlines.

Re-order table of corresponding functions with the following priorities:
1. Pure functionality is at the top
2. `os.path` functions are shown before `os` functions
3. Similar functionality is kept together
4. Functionality follows docs order where possible
Add a few missed correspondences:
- `os.path.isjunction` and `Path.is_junction`
- `os.path.ismount` and `Path.is_mount`
- `os.lstat()` and `Path.lstat()`
- `os.lchmod()` and `Path.lchmod()`
Also add footnotes describing a few differences.
