Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.
* Add sys.flags.safe_path flag.
* Add PyConfig.safe_path member.
* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
present.
One more thing that can help prevent people from using `preexec_fn`.
Also adds conditional skips to two tests exposing ASAN flakiness on the Ubuntu 20.04 Address Sanitizer Github CI system. When that build is run on more modern systems the "problem" does not show up. It seems ASAN implementation related.

``pymain_run_python()`` now imports ``readline`` and ``rlcompleter``
before sys.path is extended to include the current working directory of
an interactive interpreter. Non-interactive interpreters are not
affected.
Also move imports of ``re`` and ``keyword`` module to top level so they
are materialized early, too. The ``keyword`` module is trivial and the
``re`` is already imported via ``inspect`` -> ``linecache``.
* Map SQLITE_MISUSE to sqlite3.InterfaceError
SQLITE_MISUSE implies misuse of the SQLite C API, which, if it happens,
is _not_ a user error; it is an sqlite3 extension module error.
* Raise better errors when binding parameters fail.
Instead of always raising InterfaceError, guessing what went wrong,
raise accurate exceptions with more accurate error messages.
Fix C++ compiler warnings: "zero as null pointer constant"
(clang -Wzero-as-null-pointer-constant).
* Add the _Py_NULL macro used by static inline functions to use
nullptr in C++.
* Replace NULL with nullptr in _testcppext.cpp.
Use _Py_CAST(), _Py_STATIC_CAST() and _PyASCIIObject_CAST() in
static inline functions to fix C++ compiler warnings:
"use of old-style cast" (clang -Wold-style-cast).
test_cppext now builds the C++ test extension with -Wold-style-cast.
Help for other actions omit the default value if default is SUPPRESS or
already contains the special format string '%(default)'. Add those
special cases to BooleanOptionalAction's help formatting too.
Fixes https://bugs.python.org/issue44587 so that default=SUPPRESS is not
emitted.
Fixes https://bugs.python.org/issue38956 as this code will detect
whether '%(default)s' has already been specified in the help string.

The function fetch_server_certificate is replaced by get_server_certificate in the module. I reflected the change in the module docstrings.

Since the underlying file-like objects (either `io.BytesIO`,
or a true file object) all implement the `io.IOBase`
interface, the `SpooledTemporaryFile` should as well.
Additionally, since the underlying file object will either be an
instance of an `io.BufferedIOBase` (for binary mode) or an
`io.TextIOBase` (for text mode), methods for these classes were also
implemented.
In every case, the required methods and properties are simply delegated
to the underlying file object.

`IPv*Network` and `IPv*Interface` constructors accept a 2-tuple of
(address description, netmask) as the address parameter.
When the tuple-based address is used errors are not propagated
correctly through the `ipaddress.ip_*` helper because of the %-formatting now expecting several arguments:
In [7]: ipaddress.ip_network(("192.168.100.0", "fooo"))
...
TypeError: not all arguments converted during string formatting
Compared to:
In [8]: ipaddress.IPv4Network(("192.168.100.0", "foo"))
...
NetmaskValueError: 'foo' is not a valid netmask
Use an f-string to make sure the error is always properly formatted.

This mirrors logic in typing.get_args. The trickiness comes from how we
flatten args in collections.abc.Callable, see
