Add C++ overloads for _Py_CAST_impl() to handle 0/NULL.  This will allow
C++ extensions that pass 0 or NULL to macros using _Py_CAST() to
continue to compile.  Without this, you get an error like:

    invalid ‘static_cast’ from type ‘int’ to type ‘_object*’

The modern way to use a NULL value in C++ is to use nullptr.  However,
we want to not break extensions that do things the old way.

Note: This change is not effective on Microsoft Windows.

Cookies can store sensitive information and should therefore be protected
against unauthorized third parties. This is also described in issue python#79096.

The filesystem permissions are currently set to 644, everyone can read the
file. This commit changes the permissions to 600, only the creater of the file
can read and modify it. This improves security, because it reduces the attack
surface. Now the attacker needs control of the user that created the cookie or
a ways to circumvent the filesystems permissions.

This change is backwards incompatible. Systems that rely on world-readable
cookies will breake. However, one could argue that those are misconfigured in
the first place.

All install targets use the "all" target as synchronization point to

Documentation for `pathlib` says:

> Spurious slashes and single dots are collapsed, but double dots ('..') are not, since this would change the meaning of a path in the face of symbolic links:

However, it omits that initial double slashes also aren't collapsed.

Later, in documentation of `PurePath.drive`, `PurePath.root`, and `PurePath.name` it mentions UNC but:

- this abbreviation says nothing to a person who is unaware about existence of UNC (Wikipedia doesn't help either by [giving a disambiguation page](https://en.wikipedia.org/wiki/UNC))
- it shows up only if a person needs to use a specific property or decides to fully learn what the module provides.

For context, see the BPO entry.
