``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
