Ref. [SQLite 3.7.15 changelog](https://sqlite.org/changes.html#version_3_7_15):
_"Avoid invoking the sqlite3_trace() callback multiple times when a statement is automatically reprepared due to SQLITE_SCHEMA errors."_
A compiler that doesn't define `__has_builtin` will error out when it is
used on the same line as the check for it.

In is_typing_name(), va_end() is not always called before the
function returns. It is undefined behavior to call va_start()
without also calling va_end().
* Add test capturing missed expectation with uname_result._replace.
* bpo-42163: Override uname_result._make to allow uname_result._replace to work (for everything but 'processor'.
* Replace hard-coded length with one derived from the definition.
* Add test capturing missed expectation with copy/deepcopy on namedtuple (bpo-42189).
* bpo-42189: Exclude processor parameter when constructing uname_result.
* In _make, rely on __new__ to strip processor.
* Add blurb.
* iter is not necessary here.
* Rely on num_fields in __new__
* Add test for slices on uname
* Add test for copy and pickle.

* import pickle
* Fix equality test after pickling.
* Simply rely on __reduce__ for pickling.

* bpo-42382: In importlib.metadata, `EntryPoint` objects now expose a `.dist` object referencing the `Distribution` when constructed from a `Distribution`.
Also, sync importlib_metadata 3.3:
- Add support for package discovery under package normalization rules.
- The object returned by `metadata()` now has a formally-defined protocol called `PackageMetadata` with declared support for the `.get_all()` method.
* Add blurb
* Remove latent footnote.
Added --disable-test-modules option to the configure script:
don't build nor install test modules.

Make the Unicode dictionary of interned strings compatible with
subinterpreters.
Remove the INTERN_NAME_STRINGS macro in typeobject.c: names are
always now interned (even if EXPERIMENTAL_ISOLATED_SUBINTERPRETERS
macro is defined).
_PyUnicode_ClearInterned() now uses PyDict_Next() to no longer
allocate memory, to ensure that the interned dictionary is cleared.
Make the type attribute lookup cache per-interpreter.
Add private _PyType_InitCache() function, called by PyInterpreterState_New().
Continue to share next_version_tag between interpreters, since static
types are still shared by interpreters.
Remove MCACHE macro: the cache is no longer disabled if the
EXPERIMENTAL_ISOLATED_SUBINTERPRETERS macro is defined.
Make _PyUnicode_FromId() function compatible with subinterpreters.
Each interpreter now has an array of identifier objects (interned
strings decoded from UTF-8).
* Add PyInterpreterState.unicode.identifiers: array of identifiers
objects.
* Add _PyRuntimeState.unicode_ids used to allocate unique indexes
to _Py_Identifier.
* Rewrite the _Py_Identifier structure.
Microbenchmark on _PyUnicode_FromId(&PyId_a) with _Py_IDENTIFIER(a):
[ref] 2.42 ns +- 0.00 ns -> [atomic] 3.39 ns +- 0.00 ns: 1.40x slower
This change adds 1 ns per _PyUnicode_FromId() call in average.
When simple query dialogs (tkinter.simpledialog), message boxes
(tkinter.messagebox) or color choose dialog (tkinter.colorchooser)
are created without arguments master and parent, and the default
root window is not yet created, a new temporary hidden root window
will be created automatically. It will not be set as the default root
window and will be destroyed right after closing the dialog window.
It will help to use these simple dialog windows in programs which do
not need other GUI.
Previously, message boxes and color chooser created the blank root
window and left it after closing the dialog window, and query dialogs
just raised an exception.

When the modern text= spelling of the universal_newlines= parameter was added
for Python 3.7, check_output's special case around input=None was overlooked.
So it behaved differently with universal_newlines=True vs text=True. This
reconciles the behavior to be consistent and adds a test to guarantee it.
Also clarifies the existing check_output documentation.

* If parent is specified and mapped, the query widget is
centered at the center of parent. Its position and size
can be corrected so that it fits in the virtual root window.
* Otherwise it is centered at the center of the screen.
On Fedora 31 gdb is using python 3.7.9, calling `proxyval` on an instance with a dictionary fails because of the `dict.iteritems` usage. This PR changes the code to be compatible with py2 and py3.
This changed seemed small enough to not need an issue and news blurb, if one is required please let me know.
