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.

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.

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.

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.

When a `_PathParents` object has a drive or a root, the length of the
object is *one less* than than the length of `self._parts`, which resulted
in an off-by-one error when `path.parents[-n]` was fed through to
`self._parts[:-n - 1]`. In particular, `path.parents[-1]` was a malformed
path object with spooky properties.
This is addressed by adding `len(self)` to negative indices.

In previous versions of Python if an IntEnum member was combined with another integer type value using a bit-wise operation, the resulting value would still be the IntEnum type. This change restores that behavior.
