Move forward declarations of Python C API types to a new pytypedefs.h
header file to solve interdependency issues between header files.
pytypedefs.h contains forward declarations of the following types:
* PyCodeObject
* PyFrameObject
* PyGetSetDef
* PyInterpreterState
* PyLongObject
* PyMemberDef
* PyMethodDef
* PyModuleDef
* PyObject
* PyThreadState
* PyTypeObject
This changes cancelling() and uncancel() to return the count of pending cancellations.
This can be used to avoid bugs in certain edge cases (e.g. two timeouts going off at the same time).
Remove the HAVE_PY_SET_53BIT_PRECISION macro (moved to the internal
C API).
* Move HAVE_PY_SET_53BIT_PRECISION macro to pycore_pymath.h.
* Replace PY_NO_SHORT_FLOAT_REPR macro with _PY_SHORT_FLOAT_REPR
macro which is always defined. gcc -Wundef emits a warning when
using _PY_SHORT_FLOAT_REPR but the macro is not defined, if
pycore_pymath.h include was forgotten.
* C API docs: move PyErr_SetImportErrorSubclass docs
It was in the section about warnings, but it makes more sense to
put it with PyErr_SetImportError.
* C API docs: document closeit argument to PyRun_AnyFileExFlags
It was already documented for PyRun_SimpleFileExFlags.
* textual fixes to unicode docs
* Move paragraph about tp_dealloc into tp_dealloc section
* __aiter__ returns an async iterator, not an awaitable
Rename Include/buffer.h header file to Include/pybuffer.h to avoid
conflicts with projects having an existing "buffer.h" header file.
* Incude pybuffer.h before object.h in Python.h.
* Remove #include "buffer.h" from Include/cpython/object.h.
* Add a forward declaration of the PyObject type in pybuffer.h to fix
an inter-dependency issue.
The locale.getdefaultlocale() function is deprecated and will be
removed in Python 3.13. Use locale.setlocale(),
locale.getpreferredencoding(False) and locale.getlocale() functions
instead.
Fix parsing a numeric literal immediately (without spaces) followed by
"not in" keywords, like in "1not in x". Now the parser only emits
a warning, not a syntax error.
Curly brackets were never allowed in namespace URIs
according to RFC 3986, and so-called namespace-validating
XML parsers have the right to reject them a invalid URIs.
libexpat >=2.4.5 has become strcter in that regard due to
related security issues; with ET.XML instantiating a
namespace-aware parser under the hood, this test has no
future in CPython.

It fixes the "Text File Busy" OSError when using 'rmtree' on a
windows-managed filesystem in via the VirtualBox shared folder
(and possible other scenarios like a windows-managed network file
system).
