* gh-93442: Make C++ version of _Py_CAST work with 0/NULL. (#93500)

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.

Character ranges with upper bound less that lower bound (e.g. [c-a])
are now interpreted as empty ranges, for compatibility with other glob
pattern implementations. Previously it was re.error.

* gh-79096: Protect cookie file created by {LWP,Mozilla}CookieJar.save() (GH-93463)

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 #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
prevent race conditions with PGO builds. PGO builds use recursive make,
which can lead to two parallel `./python setup.py build` processes that
step on each others toes.

"test" targets now correctly compile PGO build in a clean repo.
