Fix destructor _pyio.BytesIO and _pyio.TextIOWrapper: initialize
their _buffer attribute as soon as possible (in the class body),
because it's used by __del__() which calls close().

I've reported the issue on https://bugs.python.org/issue37008 and now I'm trying to bring a solution to this minor issue.
I think it could be trivially backported to 3.7 branch.

…nctions with asserts
The actual overflow can never happen because of the following:
* The size of a list can't be greater than PY_SSIZE_T_MAX / sizeof(PyObject*).
* The size of a pointer on all supported plaftorms is at least 4 bytes.
* ofs is positive and less than the list size at the beginning of each iteration.

CVE-2019-9948: Avoid file reading as disallowing the unnecessary URL

PyErr_WriteUnraisable() now displays the exception even if displaying
the traceback failed. Moreover, hold a strong reference to sys.stderr
while using it.
Document that an exception must be set when calling
PyErr_WriteUnraisable(), but don't add an assertion to check it at
runtime.
Cleanup: use longer names for variables and create
write_unraisable_exc_file() subfunction.
Include windows.h rather than crtdbg.h to get STATUS_CONTROL_C_EXIT constant.
Moreover, include windows.h on Windows, not only when MSC is used.

* bpo-36929: Modify io/re tests to allow for missing mod name
For a vanishingly small number of internal types, CPython sets the
tp_name slot to mod_name.type_name, either in the PyTypeObject or the
PyType_Spec. There are a few minor places where this surfaces:
* Custom repr functions for those types (some of which ignore the
tp_name in favor of using a string literal, such as _io.TextIOWrapper)
* Pickling error messages
The test suite only tests the former. This commit modifies the test
suite to allow Python implementations to omit the module prefix.
