gh-91577: SharedMemory move imports out of methods (GH-91579)

SharedMemory.unlink() uses the unregister() function from resource_tracker. Previously it was imported in the method, but this can fail if the method is called during interpreter shutdown, for example when unlink is part of a __del__() method.

Moving the import to the top of the file, means that the unregister() method is available during interpreter shutdown.

The register call in SharedMemory.__init__() can also use this imported resource_tracker.

[3.11] gh-79579: Improve DML query detection in sqlite3 (GH-93623) (#93800)

The fix involves using pysqlite_check_remaining_sql(), not only to check
for multiple statements, but now also to strip leading comments and
whitespace from SQL statements, so we can improve DML query detection.

pysqlite_check_remaining_sql() is renamed lstrip_sql(), to more
accurately reflect its function, and hardened to handle more SQL comment
corner cases.

gh-91317: Document that Path does not collapse initial `//` (GH-32193)

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.

[3.11] gh-79096: Protect cookie file created by {LWP,Mozilla}CookieJar.save() (GH-93463) (GH-93636)

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.
