bpo-35813: Tests and docs for shared_memory (#11816)
* Added tests for shared_memory submodule.

* Added tests for ShareableList.

* Fix bug in allocationn size during creation of empty ShareableList illuminated by existing test run on Linux.

* Initial set of docs for shared_memory module.

* Added docs for ShareableList, added doctree entry for shared_memory submodule, name refactoring for greater clarity.

* Added examples to SharedMemoryManager docs, for ease of documentation switched away from exclusively registered functions to some explicit methods on SharedMemoryManager.

* Wording tweaks to docs.

* Fix test failures on Windows.

* Added tests around SharedMemoryManager.

* Documentation tweaks.

* Fix inappropriate test on Windows.

* Further documentation tweaks.

* Fix bare exception.

* Removed __copyright__.

* Fixed typo in doc, removed comment.

* Updated SharedMemoryManager preliminary tests to reflect change of not supporting all registered functions on SyncManager.

* Added Sphinx doctest run controls.

* CloseHandle should be in a finally block in case MapViewOfFile fails.

* Missed opportunity to use with statement.

* Switch to self.addCleanup to spare long try/finally blocks and save one indentation, change to use decorator to skip test instead.

* Simplify the posixshmem extension module.

Provide shm_open() and shm_unlink() functions.  Move other
functionality into the shared_memory.py module.

* Added to doc around size parameter of SharedMemory.

* Changed PosixSharedMemory.size to use os.fstat.

* Change SharedMemory.buf to a read-only property as well as NamedSharedMemory.size.

* Marked as provisional per PEP411 in docstring.

* Changed SharedMemoryTracker to be private.

* Removed registered Proxy Objects from SharedMemoryManager.

* Removed shareable_wrap().

* Removed shareable_wrap() and dangling references to it.

* For consistency added __reduce__ to key classes.

* Fix for potential race condition on Windows for O_CREX.

* Remove unused imports.

* Update access to kernel32 on Windows per feedback from eryksun.

* Moved kernel32 calls to _winapi.

* Removed ShareableList.copy as redundant.

* Changes to _winapi use from eryksun feedback.

* Adopt simpler SharedMemory API, collapsing PosixSharedMemory and WindowsNamedSharedMemory into one.

* Fix missing docstring on class, add test for ignoring size when attaching.

* Moved SharedMemoryManager to managers module, tweak to fragile test.

* Tweak to exception in OpenFileMapping suggested by eryksun.

* Mark a few dangling bits as private as suggested by Giampaolo.

Segev Finer b2a6083eb0 bpo-19764: Implemented support for subprocess.Popen(close_fds=True) on Windows (#1218)
Even though Python marks any handles it opens as non-inheritable there
is still a race when using `subprocess.Popen` since creating a process
with redirected stdio requires temporarily creating inheritable handles.
By implementing support for `subprocess.Popen(close_fds=True)` we fix
this race.

In order to implement this we use PROC_THREAD_ATTRIBUTE_HANDLE_LIST
which is available since Windows Vista. Which allows to pass an explicit
list of handles to inherit when creating a process.

This commit also adds `STARTUPINFO.lpAttributeList["handle_list"]`
which can be used to control PROC_THREAD_ATTRIBUTE_HANDLE_LIST
directly.

bpo-29240: PEP 540: Add a new UTF-8 Mode (#855)
* Add -X utf8 command line option, PYTHONUTF8 environment variable
  and a new sys.flags.utf8_mode flag.
* If the LC_CTYPE locale is "C" at startup: enable automatically the
  UTF-8 mode.
* Add _winapi.GetACP(). encodings._alias_mbcs() now calls
  _winapi.GetACP() to get the ANSI code page
* locale.getpreferredencoding() now returns 'UTF-8' in the UTF-8
  mode. As a side effect, open() now uses the UTF-8 encoding by
  default in this mode.
* Py_DecodeLocale() and Py_EncodeLocale() now use the UTF-8 encoding
  in the UTF-8 Mode.
* Update subprocess._args_from_interpreter_flags() to handle -X utf8
* Skip some tests relying on the current locale if the UTF-8 mode is
  enabled.
* Add test_utf8mode.py.
* _Py_DecodeUTF8_surrogateescape() gets a new optional parameter to
  return also the length (number of wide characters).
* pymain_get_global_config() and pymain_set_global_config() now
  always copy flag values, rather than only copying if the new value
  is greater than the old value.

Victor Stinner 850a18e03e bpo-30768: Recompute timeout on interrupted lock (GH-4103)
Fix the pthread+semaphore implementation of
PyThread_acquire_lock_timed() when called with timeout > 0 and
intr_flag=0: recompute the timeout if sem_timedwait() is interrupted
by a signal (EINTR).

See also the PEP 475.

The pthread implementation of PyThread_acquire_lock() now fails with
a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done
in the Windows implementation.

The check prevents any risk of overflow in PyThread_acquire_lock().

Add also PY_DWORD_MAX constant.

Sylvain 7445381c60 bpo-30600: Fix error messages (condition order in Argument Clinic) (#2051)
The function '_PyArg_ParseStack()' and
'_PyArg_UnpackStack' were failing (with error
"XXX() takes Y argument (Z given)") before
the function '_PyArg_NoStackKeywords()' was called.
Thus, the latter did not raise its more meaningful
error : "XXX() takes no keyword arguments".
