gh-146480: Override the exception in _PyErr_SetKeyError() (#146486) 
If _PyErr_SetKeyError() is called with an exception set, it now
replaces the current exception with KeyError (as expected), instead
of setting a SystemError or failing with a fatal error (in debug
mode).

gh-128341: Use _Py_ABI_SLOT in stdlib modules (#145770) 
Rename from _Py_INTERNAL_ABI_SLOT to _Py_ABI_SLOT
and define the macro using _PyABIInfo_DEFAULT.

Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.

_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.

gh-145264: Do not ignore excess Base64 data after the first padded quad (GH-145267) 
Base64 decoder (see binascii.a2b_base64(), base64.b64decode(), etc)
no longer ignores excess data after the first padded quad in non-strict
(default) mode.  Instead, in conformance with RFC 4648, it ignores the
pad character, "=", if it is present before the end of the encoded data.

gh-145966: Fix _csv DIALECT_GETATTR macro silently masking non-AttributeError exceptions (GH-145974) 
The DIALECT_GETATTR macro in dialect_new() unconditionally called
PyErr_Clear() when PyObject_GetAttrString() failed, which suppressed
all exceptions including MemoryError, KeyboardInterrupt, and
RuntimeError. Now only AttributeError is cleared; other exceptions
propagate via the existing error handling path.

gh-144545: Improve handling of default values in Argument Clinic (GH-146016) 
* Add the c_init_default attribute which is used to initialize the C variable
  if the default is not explicitly provided.
* Add the c_default_init() method which is used to derive c_default from
  default if c_default is not explicitly provided.
* Explicit c_default and py_default are now almost always have precedence
  over the generated value.
* Add support for bytes literals as default values.
* Improve support for str literals as default values (support non-ASCII
  and non-printable characters and special characters like backslash or quotes).
* Fix support for str and bytes literals containing trigraphs, "/*" and "*/".
* Improve support for default values in converters "char" and "int(accept={str})".
* Converter "int(accept={str})" now requires 1-character string instead of
  integer as default value.
* Add support for non-None default values in converter "Py_buffer": NULL,
  str and bytes literals.
* Improve error handling for invalid default values.
* Rename Null to NullType for consistency.
