 bpo-33721: Make some os.path functions and pathlib.Path methods be tolerant to invalid paths.  (#7695)

Such functions as os.path.exists(), os.path.lexists(), os.path.isdir(),
os.path.isfile(), os.path.islink(), and os.path.ismount() now return False
instead of raising ValueError or its subclasses UnicodeEncodeError
and UnicodeDecodeError for paths that contain characters or bytes
unrepresentative at the OS level.

Add C API function PyCompile_OpcodeStackEffectWithJump().

Also rename corresponding attributes, parameters and variables.

The `gather` method requires to close the parenthesis, but it is being closed twice.

Add a new -X coerce_c_locale command line option to control C locale
coercion (PEP 538).

Py_Initialize() and Py_Main() cannot enable the C locale coercion
(PEP 538) anymore: it is always disabled. It can now only be enabled
by the Python program ("python3).

test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8
nor PYTHONCOERCECLOCALE, these variables are already set in the
parent.

_PyCoreConfig:

* Rename coerce_c_locale to _coerce_c_locale
* Rename coerce_c_locale_warn to _coerce_c_locale_warn

These fields are now private (name prefixed by "_").

The test tries to fill the receiver's socket buffer and expects an
error. But the RDS protocol doesn't require that. Moreover, the Linux
implementation of RDS expects that the producer of the messages
reduces its rate, it's not the role of the receiver to trigger an
error.

The test fails on Fedora 28 by design, so remove it.

This reverts commit afde1c1a.

Also convert os.get_blocking() and os.set_blocking().

Include ``openssl/dh.h`` header file to fix implicit function declaration of ``DH_free()``.

Two major changes:
- Move case statements out of the TARGET macro.
- Move PREDICT macro invocations after the case label.

Assume tzname exists. Only use a hack to compute altzone if it's not defined.

* Skip posix_spawn scheduler tests on BSD. We were already skyping similar tests as the behaviour can depend on the implementation in some cases.

When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter.
