gh-107913: Fix possible losses of OSError error codes (GH-107930)
Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be
called immediately after using the C API which sets errno or the Windows
error code.

gh-106320: Remove private _PyDict functions (#108449)
Move private functions to the internal C API (pycore_dict.h):

* _PyDictView_Intersect()
* _PyDictView_New()
* _PyDict_ContainsId()
* _PyDict_DelItemId()
* _PyDict_DelItem_KnownHash()
* _PyDict_GetItemIdWithError()
* _PyDict_GetItem_KnownHash()
* _PyDict_HasSplitTable()
* _PyDict_NewPresized()
* _PyDict_Next()
* _PyDict_Pop()
* _PyDict_SetItemId()
* _PyDict_SetItem_KnownHash()
* _PyDict_SizeOf()

No longer export most of these functions.

Move also the _PyDictViewObject structure to the internal C API.

Move dict_getitem_knownhash() function from _testcapi to the
_testinternalcapi extension. Update test_capi.test_dict for this
change.

gh-108240: Add _PyCapsule_SetTraverse() internal function (#108339)
The _socket extension uses _PyCapsule_SetTraverse() to visit and clear
the socket type in the garbage collector. So the _socket.socket type
can be cleared in some corner cases when it wasn't possible before.

gh-104432: Use `memcpy()` to avoid misaligned loads (#104433)
Fix potential unaligned memory access on C APIs involving returned sequences
of `char *` pointers within the :mod:`grp` and :mod:`socket` modules. These

gh-102255: Improve build support for Windows API partitions (GH-102256)
Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs).
CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes.
`MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.

gh-74895: getaddrinfo no longer raises OverflowError (#2435)

gh-100795: Don't call freeaddrinfo on failure. (#101252)
When getaddrinfo returns an error, the output pointer is in an unknown state
Don't call freeaddrinfo on it.  See the issue for discussion and details with
links to reasoning.  _Most_ libc getaddrinfo implementations never modify the
output pointer unless they are returning success.

gh-98030: socket: add missing TCP socket options (#98031)
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.

bpo-15999: Accept arbitrary values for boolean parameters. (#15609)

gh-94821: Fix autobind of empty unix domain address (GH-94826)
When binding a unix socket to an empty address on Linux, the socket is
automatically bound to an available address in the abstract namespace.

    >>> s = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM)
    >>> s.bind("")
    >>> s.getsockname()
    b'\x0075499'

Since python 3.9, the socket is bound to the one address:

    >>> s.getsockname()
    b'\x00'

And trying to bind multiple sockets will fail with:

    Traceback (most recent call last):
      File "/home/nsoffer/src/cpython/Lib/test/test_socket.py", line 5553, in testAutobind
        s2.bind("")
    OSError: [Errno 98] Address already in use

Added 2 tests:
- Auto binding empty address on Linux
- Failing to bind an empty address on other platforms
