bpo-45995: add "z" format specifer to coerce negative 0 to zero (GH-30049) 
Add "z" format specifier to coerce negative 0 to zero.

See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion.
This covers `str.format()` and f-strings.  Old-style string interpolation is not supported.

bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657) 
Add new functions to pack and unpack C double (serialize and
deserialize):

* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()

Document these functions and add unit tests.

Rename private functions and move them from the internal C API
to the public C API:

* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()

Replace the "unsigned char*" type with "char*" which is more common
and easy to use.

bpo-46852: Remove the float.__set_format__() method (GH-31585) 
Remove the undocumented private float.__set_format__() method,
previously known as float.__set_format__() in Python 3.7. Its
docstring said: "You probably don't want to use this function. It
exists mainly to be used in Python's test suite."

bpo-43413: Fix handling keyword arguments in subclasses of some buitin classes (GH-26456) 
* Constructors of subclasses of some buitin classes (e.g. tuple, list,
  frozenset) no longer accept arbitrary keyword arguments.
* Subclass of set can now define a __new__() method with additional
  keyword parameters without overriding also __init__().

not impacted. Patch by Karthikeyan Singaravelan.

bpo-34087: Fix buffer overflow in int(s) and similar functions (GH-8274) 
`_PyUnicode_TransformDecimalAndSpaceToASCII()` missed trailing NUL char.
It caused buffer overflow in `_Py_string_to_number_with_underscores()`.

This bug is introduced in 9b6c60cb.

Benjamin Peterson 2bb69a5b4e bpo-31373: remove overly strict float range checks (#3486) 
This undoes a853a8ba78 except for the pytime.c
parts. We want to continue to allow IEEE 754 doubles larger than FLT_MAX to be
rounded into finite floats. Tests were added to very this behavior.

Serhiy Storchaka 16931c3559 Issue #26983: float() now always return an instance of exact float. 
The deprecation warning is emitted if __float__ returns an instance of
a strict subclass of float.  In a future versions of Python this can
be an error.

Martin Panter eeb896c411 Issue #24802: Copy bytes-like objects to null-terminated buffers if necessary 
This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.

Zachary Ware 38c707e7e0 Issue #21741: Update 147 test modules to use test discovery. 
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.
