Subject: [PATCH 1/2] Fix pickling URLs with Python 3.15.0a6+ (Fixes #1632)

In Python 3.15 urllib.parse.SplitResult gained a new __getstate__
method which fails when called on instances created via tuple.__new__:
https://github.com/python/cpython/commit/c5cfcdf1
Returning self._val directly instead of creating a new SplitResult
instance avoids the problematic code path, and is backwards compatible.
