* gh-113536: Expose `os.waitid` on macOS
This API has been available on macOS for a long time, but was
explicitly excluded due to unspecified problems with the API
in ancient versions of macOS.
* Document that the API is available on macOS starting in Python 3.13
Add support for `os.POSIX_SPAWN_CLOSEFROM` and
`posix_spawn_file_actions_addclosefrom_np` and have the `subprocess` module use
them when available. This means `posix_spawn` can now be used in the default
`close_fds=True` situation on many platforms.

* Allow posix_spawn to inherit environment form parent environ variable.
With this change, posix_spawn call can behave similarly to execv with regards to environments when used in subprocess functions.
* gh-105912: document gotcha with using os.fork on macOS
Using ``fork(2)`` on macOS when also using higher-level
system APIs in the parent proces can crash on macOS because
those system APIs are not written to handle this usage
pattern.
There's nothing we can do about this other than documenting
the problem.

POSIX specifies that implementations are not required to support changing the
file mode of symbolic links, but may do so.
Consequently, `lchmod()` is not part of POSIX (but mentioned for implementations
which do support the above).
The current wording of the availability of `os.lchmod()` is rather vague and
improved to clearly tell which POSIX/Unix/BSD-like support the function in
general (those that support changing the file mode of symbolic links).
Further, some examples of major implementations are added.
Data for the BSDs taken from their online manpages.

* Refactor os_sched_getaffinity_impl(): move variable definitions to
their first assignment.
* Fix test_posix.test_sched_getaffinity(): restore the old CPU mask
when the test completes!
* Doc: Specify that os.cpu_count() counts *logicial* CPUs.
* Doc: Specify that os.sched_getaffinity(0) is related to the calling
thread.
Document the `os.fork` posix threads detected `DeprecationWarning` in 3.12 What's New, os, multiprocessing, and concurrent.futures docs.
Many reviews and doc cleanup edits by Adam & Hugo. 🥳

- name the last parameter *whence*, like it is for seek() methods on
file objects
- add param docstrings
- structure the valid *whence* params

This adds a number of PRIO_DARWIN_* constants to the os module for use with os.setpriority.

This deprecates `st_ctime` fields on Windows, with the intent to change them to contain the correct value in 3.14. For now, they should keep returning the creation time as they always have.
* fileutils: handle non-blocking pipe IO on Windows
Handle erroring operations on non-blocking pipes by reading the _doserrno code.
Limit writes on non-blocking pipes that are too large.
* Support blocking functions on Windows
Use the GetNamedPipeHandleState and SetNamedPipeHandleState Win32 API functions to add support for os.get_blocking and os.set_blocking.
os.remove can raise PermissionError instead of IsADirectoryError,
when the object to be removed is a directory (in particular on
macOS).
This reverts a change done in #14262.
Added os.setns and os.unshare to easily switch between namespaces
on Linux.
