53345a40bc (Merge 3.4) Issue #23571: Fix reentrant call to Py_FatalError() 
Flushing sys.stdout and sys.stderr in Py_FatalError() can call again
Py_FatalError(). Add a reentrant flag to detect this case and just abort at the
second call.

e0deff31d3 (Merge 3.4) Issue #23571: Py_FatalError() now tries to flush sys.stdout and 
sys.stderr

It should help to see exceptions when stderr if buffered: PyErr_Display() calls
sys.stderr.write(), it doesn't write into stderr file descriptor directly.

de821befd4 Issue #23571: PyErr_FormatV() and PyErr_SetObject() now always clear the 
current exception because they can run arbitrary Python code and so no
exception must be set.

91afbb6088 Issue #23753: Move _Py_wstat() from Python/fileutils.c to Modules/getpath.c 
I expected more users of _Py_wstat(), but in practice it's only used by
Modules/getpath.c. Move the function because it's not needed on Windows.
Windows uses PC/getpathp.c which uses the Win32 API (ex: GetFileAttributesW())
not the POSIX API.

10dc48497e (Merge 3.4) Issue #23571: Enhance Py_FatalError() 
* Display the current Python stack if an exception was raised but the exception
  has no traceback
* Disable faulthandler if an exception was raised (before it was only disabled
  if no exception was raised)
* To display the current Python stack, call PyGILState_GetThisThreadState()
  which works even if the GIL was released

f329878e74 Issue #23753: Python doesn't support anymore platforms without stat() or 
fstat(), these functions are always required.

Remove HAVE_STAT and HAVE_FSTAT defines, and stop supporting DONT_HAVE_STAT and
DONT_HAVE_FSTAT.

efde146b0c Issue #23571: _Py_CheckFunctionResult() now gives the name of the function 
which returned an invalid result (result+error or no result without error) in
the exception message.

Add also unit test to check that the exception contains the name of the
function.

Special case: the final _PyEval_EvalFrameEx() check doesn't mention the
function since it didn't execute a single function but a whole frame.

9a8089b32a Issue #23646: Enhance precision of time.sleep() and socket timeout when 
interrupted by a signal

Add a new _PyTime_AddDouble() function and remove _PyTime_ADD_SECONDS() macro.
The _PyTime_ADD_SECONDS only supported an integer number of seconds, the
_PyTime_AddDouble() has subsecond resolution.

66aab0c4b5 Issue #23708: Add _Py_read() and _Py_write() functions to factorize code handle 
EINTR error and special cases for Windows.

These functions now truncate the length to PY_SSIZE_T_MAX to have a portable
and reliable behaviour. For example, read() result is undefined if counter is
greater than PY_SSIZE_T_MAX on Linux.

9eb57c5fa5 Issue #22181: The availability of the getrandom() is now checked in configure, 
and stored in pyconfig.h as the new HAVE_GETRANDOM_SYSCALL define.

59f7fb29ec Issue #22181: On Linux, os.urandom() now uses the new getrandom() syscall if 
available, syscall introduced in the Linux kernel 3.17. It is more reliable
and more secure, because it avoids the need of a file descriptor and waits
until the kernel has enough entropy.

4a7cc88472 Issue #23571: PyObject_Call(), PyCFunction_Call() and call_function() now 
raise a SystemError if a function returns a result and raises an exception.
The SystemError is chained to the previous exception.

Refactor also PyObject_Call() and PyCFunction_Call() to make them more readable.

Remove some checks which became useless (duplicate checks).
