translating the documentation. Patch written by Julien Palard who is
translating Python 3.5 doc to french. Text of other licenses already used

Issue #24520: On FreeBSD, fpgetmask() was deprecated long time ago.
fedisableexcept() is now preferred.

Issue #26154: Add a new private _PyThreadState_UncheckedGet() function which
gets the current thread state, but don't call Py_FatalError() if it is NULL.

Python 3.5.1 removed the _PyThreadState_Current symbol from the Python C API to
no more expose complex and private atomic types. Atomic types depends on the
compiler or can even depend on compiler options. The new function
_PyThreadState_UncheckedGet() allows to get the variable value without having
to care of the exact implementation of atomic types.

Changes:

* Replace direct usage of the _PyThreadState_Current variable with a call to
  _PyThreadState_UncheckedGet().
* In pystate.c, replace direct usage of the _PyThreadState_Current variable
  with the PyThreadState_GET() macro for readability.
* Document also PyThreadState_Get() in pystate.h

A machine can have more than one IP addresses so
socket.gethostbyname(socket.gethostname()) probably won't return the correct
one.

The previous test relied on a remote server, which currently seems to be
shutting the connection down once TLS has been set up, causing an EOFError.
Now the test is implemented using a minimal NNTP server running in a
background thread.

Some dependencies of pip import threading module unconditionally so
we need to skip the test to make buildbots happy.

Issue26017 - Suggest enclosing command args in double quotes when using characters which get interpreted by shell.

Re-encode CREDITS.txt to utf-8 and open it with 'utf-8'.

 Issue26035 - Correct the argument names used in the docs of the traceback module. Make it consistent with module args.

Otherwise, GDB seems to affect the terminal's foreground process group,
interfering with test_ioctl, which does not expect the foreground process to
change during the test. This change also solves the problem of the tests
being stopped in the shell if test_gdb is run twice in parallel.

Previously zipimport mistakenly limited namespace support to only the
top-level of the zipfile when it should have supported an arbitrary
depth.
