GH-119169: Simplify `os.walk()` exception handling (#121435) 
Handle errors from `os.scandir()` and `ScandirIterator` similarly, which
lets us loop over directory entries with `for`.

GH-89727: Fix FD leak on `os.fwalk()` generator finalization. (#119766) 
Follow-up to 3c890b50. Ensure we `os.close()` open file descriptors when
the `os.fwalk()` generator is finalized.

GH-89727: Fix `os.fwalk()` recursion error on deep trees (#119638) 
Implement `os.fwalk()` using a list as a stack to avoid emitting recursion
errors on deeply nested trees.

GH-89727: Partially fix `shutil.rmtree()` recursion error on deep trees (#119634) 
Make `shutil._rmtree_unsafe()` call `os.walk()`, which is implemented
without recursion.

`shutil._rmtree_safe_fd()` is not affected and can still raise a recursion
error.

gh-109649: Add os.process_cpu_count() function (#109907) 
* 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.

Guido van Rossum 48b069a003
bpo-39481: Implementation for PEP 585 (#18239) 
This implements things like `list[int]`,
which returns an object of type `types.GenericAlias`.
This object mostly acts as a proxy for `list`,
but has attributes `__origin__` and `__args__`
that allow recovering the parts (with values `list` and `(int,)`.

There is also an approximate notion of type variables;
e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`.
Type variables are objects of type `typing.TypeVar`.

bpo-40094: Add os.waitstatus_to_exitcode() (GH-19201) 
Add os.waitstatus_to_exitcode() function to convert a wait status to an
exitcode.

Suggest waitstatus_to_exitcode() usage in the documentation when
appropriate.

Use waitstatus_to_exitcode() in:

* multiprocessing, os, subprocess and _bootsubprocess modules;
* test.support.wait_process();
* setup.py: run_command();
* and many tests.

bpo-39395: putenv() and unsetenv() always available (GH-18135) 
The os.putenv() and os.unsetenv() functions are now always available.

On non-Windows platforms, Python now requires setenv() and unsetenv()
functions to build.

Remove putenv_dict from posixmodule.c: it's not longer needed.

Recursing 3ce3dea606 Use generator instead of list in code examples (GH-11203)

Benjamin Peterson 52dee687af
Assume the raw environ is always declared. (GH-8707) 
posixmodule.c always declares environ, so don't bother catching a NameError in os.py.
