If the PyObject_MALLOC() call failed in PyType_FromSpecWithBases(),
PyObject_Free() would be called on a static string in type_dealloc().

The Cache and Statement objects are undocumented and implementation
details of the sqlite3 module.

They aren't usable from pure Python code.

bpo-36851: Clean the frame stack if the execution ends with a return and the stack is not empty (GH-13191)

Also provide better grouping of the tokenizer tests.

Adds ㋿.

Enable custom reduction callback registration for functions and classes in
_pickle.c, using the new Pickler's attribute ``reducer_override``.

If a "=" is specified a the end of an f-string expression, the f-string will evaluate to the text of the expression, followed by '=', followed by the repr of the value of the expression.

Allow reduction methods to return a 6-item tuple where the 6th item specifies a
custom state-setting method that's called instead of the regular
``__setstate__`` method.

When the future returned by shield is cancelled, its completion callback of the
inner future is not removed. This makes the callback list of inner inner future
grow each time a shield is created and cancelled.

This change unregisters the callback from the inner future when the outer
future is cancelled.

(lint cleanup) This import causes an argument parameter to shadow the global import name.

*Moved from python/asyncio#493.*

This PR fixes issue python/asyncio#480, as explained in [this comment](https://github.com/python/asyncio/issues/480#issuecomment-278703828).

The `_SelectorDatagramTransport.sendto` method has to be modified ~~so `_sock.sendto` is used in all cases (because it is tricky to reliably tell if the socket is connected or not). Could that be an issue for connected sockets?~~ *EDIT* ... so `_sock.send` is used only if `_sock` is connected.

It also protects `socket.getsockname` against `OSError` in `_SelectorTransport`. This might happen on Windows if the socket is not connected (e.g. for UDP broadcasting).

Modern Linux distros such as Debian Buster have default OpenSSL system
configurations that reject connections to servers with weak certificates
by default.  This causes our test suite run with external networking
resources enabled to skip these tests when they encounter such a failure.

Fixing the network servers is a separate issue.

Classes that define __str__ the same as __repr__ can
just inherit it from object.
