(cherry picked from commit 8e04186889)
Define _CRT_SECURE_NO_WARNINGS in the Visual Studio pythoncore
project to make quiet security warnings when building zlib C files
(Modules\zlib\ subdirectory).
* posixpath.expanduser() now returns the input path unchanged if
the HOME environment variable is not set and pwd.getpwuid() raises
KeyError (the current user identifier doesn't exist in the password
database).
* Add test_no_home_directory() to test_site.

When running test_bdb.py as a script, `import test_module` would be
importing the existing Lib/test/test_modules.py instead of the
tempcwd/test_module.py module which was dynamically created by
test_bdb.py itself.

They can be exposed when some C API calls fail due to lack of
memory.
* Failed Py_BuildValue() could cause an assertion error in the
following TextIOWrapper.tell().
* initvalue could leak in StringIO.__getstate__() after failed
PyDict_Copy().

When Python is compiled in debug mode, PyMem_Malloc() uses debug
hooks, but it also uses pymalloc allocator instead of malloc().
Problem: pymalloc is not thread-safe, whereas PyMem_Malloc() is
thread-safe in release mode (it's a thin wrapper to malloc() in this
case).
Modify the debug hook to use malloc() for PyMem_Malloc().
The pthread implementation of PyThread_start_new_thread() now uses
malloc/free rather than PyMem_Malloc/PyMem_Free, since the latters
are not thread-safe.
Fix an undefined behaviour in the pthread implementation of
PyThread_start_new_thread(): add a function wrapper to always return
NULL.
Add pythread_callback struct and pythread_wrapper() to thread_pthread.h.
(cherry picked from commit 9eea6eaf23)
testAccept() and testRecv() of test_socket.NonBlockingTCPTests have a
race condition: time.sleep() is used as a weak synchronization
primitive and the tests fail randomly on slow buildbots.
Use a reliable threading.Event to fix these tests.
Other changes:
* Replace send() with sendall()
* Add a timeout to select() in testAccept() and testRecv()
* Use addCleanup() to close sockets
* Use assertRaises()

On Windows, test_env_changed() of test_regrtest is now skipped
because it fails randomly for an unknown reason on "x86 Windows XP
VS9.0 2.7" buildbot worker.
Fixes assertion failures in _datetimemodule.c
introduced in the previous fix (see bpo-31752).
Rather of trying to handle an int subclass as exact int,
let it to use overridden special methods, but check the
result of divmod().

This typo doesn't affect the result because wrong bits are discarded
on implicit conversion to unsigned char, but it trips UBSan
with -fsanitize=implicit-integer-truncation.

The test depended on '/usr/share/zoneinfo/posixrules' or equivalent
because it set TZ without explicit DST transition rules. At least
on OpenSUSE Tumbleweed that file is linked to '/etc/localtime',
making the test fail with certain local timezones,
such as 'Europe/Moscow' which doesn't have DST transitions since 2011.

Two kind of mistakes:
1. Missed space. After concatenating there is no space between words.
2. Missed comma. Causes unintentional concatenating in a list of strings.
