* Move dictobject.h code surrounded by "#ifndef Py_LIMITED_API"
to a new Include/cpython/dictobject.h header file.
* Add PyAPI_FUNC() to _PyDictView_New().
* Reorganize dictobject.h: move views and iterators at the end.
Regression introduced in e3ce695 and 25b804a, where the old parameter
update_tryorder to _synthesize was first ignored, then given the opposite
value in the attempt to fix bpo-31014.
* Move object.h code surrounded by "#ifndef Py_LIMITED_API"
to a new Include/cpython/object.h header file.
* "typedef struct _typeobject PyTypeObject;" is now always defined
in object.h, but if Py_LIMITED_API is not defined,
Include/cpython/object.h also defines the structure.
* Complete the printfunc comment to mention Py_LIMITED_API define.
Fix str.format(), float.__format__() and complex.__format__() methods
for non-ASCII decimal point when using the "n" formatter.
Changes:
* Rewrite _PyUnicode_InsertThousandsGrouping(): it now requires
a _PyUnicodeWriter object for the buffer and a Python str object
for digits.
* Rename FILL() macro to unicode_fill(), convert it to static inline function,
add "assert(0 <= start);" and rework its code.
Add "assert(PyTuple_Check(op));" to _PyTuple_CAST() to check that the
argument is a tuple object in debug mode.
PyTuple_GET_SIZE() now uses _PyTuple_CAST() to get its assertion.
There are some same consts in a module. This commit merges them into
single instance. It reduces number of objects in memory after loading modules.

Importing ProcessPoolExecutor may hang or cause an error when the import
accesses urandom on a low resource platform
https://bugs.python.org/issue29877
The "-I" command line option (run Python in isolated mode) is now
also copied by the multiprocessing and distutils modules when
spawning child processes. Previously, only -E and -s options (enabled
by -I) were copied.
subprocess._args_from_interpreter_flags() now copies the -I flag.
Include/*.h should be the "portable Python API", whereas
Include/cpython/*.h should be the "CPython API": CPython
implementation details.
Changes:
* Create Include/cpython/ subdirectory
* "make install" now creates $prefix/include/cpython and copy
Include/cpython/* to $prefix/include/cpython
* Create Include/cpython/objimpl.h: move objimpl.h code
surrounded by "#ifndef Py_LIMITED_API" to cpython/objimpl.h.
* objimpl.h now includes cpython/objimpl.h
* Windows installer (MSI) now also install Include/ subdirectories:
Include/cpython/ and Include/internal/.
That section is a tip on how to kill process on Windows for Python prior to 2.7 and 3.2.
3.1 end of support was April 2012 and 2.6 was October 2013, so that hasn't been need for supported versions of Python for more than 5 years. Beside not being needed anymore for a long time, when I read it with the eyes of a Python profane, it makes Python looks bad, like a language from the parts with warts you need to circumvent.
Let's delete that :)
bpo-34523, bpo-35290: C locale coercion now resets the Python
internal "force ASCII" mode. This change fix the filesystem encoding
on FreeBSD CURRENT, which has a new "C.UTF-8" locale, when
the UTF-8 mode is disabled.
Add _Py_ResetForceASCII(): _Py_SetLocaleFromEnv() now calls it.
If _PyObject_Dump() detects that the object is freed, don't try to
dump it (exit immediately).
Enhance also _PyObject_IsFreed(): it now detects if the pointer
itself looks like freed memory.
os_read_impl() now also truncates the size to _PY_READ_MAX
on macOS, to avoid to allocate a larger buffer even if _Py_read() is
limited to _PY_READ_MAX bytes (ex: INT_MAX on macOS).
When iterating using asdl_seq_LEN(), use 'Py_ssize_t' type instead of
'int' for the iterator variable, to avoid downcast on 64-bit platforms.
_Py_asdl_int_seq_new() now also ensures that the index is greater than
or equal to 0.
CryptGenRandom() maximum size is PY_DWORD_MAX, not INT_MAX.
Use DWORD type for the 'chunk' variable

Explicit cast a pointer difference (intptr_t) to int to fix
two warnings on 64-bit Windows:
Modules\pyexpat.c(1181): warning C4244: 'initializing':
conversion from '__int64' to 'int', possible loss of data
Modules\pyexpat.c(1192): warning C4244: 'initializing':
conversion from '__int64' to 'int', possible loss of data
Fixed the following compiler warning in multibytecodec.c:
warning C4244: '=': conversion from 'Py_ssize_t'
to 'unsigned char', possible loss of data
Cast Py_ssize_t to unsigned char: the maximum value is checked
on the previous line.
Don't pass complex expressions but regular variables to Python
macros.
* _datetimemodule.c: split single large "if" into two "if"
in date_new(), time_new() and datetime_new().
* _pickle.c, load_extension(): flatten complex "if" expression into
more regular C code.
* _ssl.c: addbool() now uses a temporary bool_obj to only evaluate
the value once.
* weakrefobject.c: replace "Py_INCREF(result = proxy);"
with "result = proxy; Py_INCREF(result);"
* Add _PyObject_ASSERT_FROM() and _PyObject_ASSERT_FAILED_MSG()
macros.
* PyObject_GC_Track() now calls _PyObject_ASSERT_FAILED_MSG(),
instead of Py_FatalError(), if the object is already tracked, to
dump more information on error.
* _PyObject_GC_TRACK() no longer checks if the object is already
tracked at runtime, use an assertion instead for best performances;
PyObject_GC_Track() still checks at runtime.
* pycore_object.h now includes pycore_pystate.h.
* Convert _PyObject_GC_TRACK() and _PyObject_GC_UNTRACK() macros to
inline functions.
