The itemsize returned in a memoryview of a ctypes array is now computed from the item type, instead of dividing the total size by the length and assuming that the length is not zero.

An earlier commit only defined check_ticks_per_second() when HAVE_TIMES is defined. However, we also need it when HAVE_CLOCK is defined. This primarily affects Windows.

A few TCP socket options have been added to the Linux kernel these last
few years.

This commit adds all the ones available in Linux 6.0:

  https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91

While at it, the TCP_FASTOPEN option has been moved lower in the list
just to keep the same order as in tcp.h to ease future synchronisations.

The Py_CLEAR(), Py_SETREF() and Py_XSETREF() macros now only evaluate
their arguments once. If an argument has side effects, these side
effects are no longer duplicated.

Use temporary variables to avoid duplicating side effects of macro
arguments. If available, use _Py_TYPEOF() to avoid type punning.
Otherwise, use memcpy() for the assignment to prevent a
miscompilation with strict aliasing caused by type punning.

Add _Py_TYPEOF() macro: __typeof__() on GCC and clang.

Add test_py_clear() and test_py_setref() unit tests to _testcapi.

asyncio.get_event_loop() now always return either running event loop or
the result of get_event_loop_policy().get_event_loop() call. The latter
should now raise an RuntimeError if no current event loop was set
instead of creating and setting a new event loop.

It affects also a number of asyncio functions and constructors which
call get_event_loop() implicitly: ensure_future(), shield(), gather(),
etc.

DeprecationWarning is no longer emitted if there is no running event loop but
the current event loop was set.

Provide consistent and informative error messages in function struct.pack when its integral arguments are not in range.

builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

This cleanup up resolves a few subtle bugs and makes the implementation for multi-phase init much cleaner.

Previously *consumed was not set in this case.

The implementation of __sizeof__() methods using _PyObject_SIZE() now
use an unsigned type (size_t) to compute the size, rather than a signed
type (Py_ssize_t).

Cast explicitly signed (Py_ssize_t) values to unsigned type
(Py_ssize_t).
