Use stdlib urlparse

The wrapper swift wrote for IPv6 support hasn't been necessary since
dropping support for Python 2.6 back in 2015. See

- https://github.com/openstack/swift/commit/67de0c8
- https://github.com/python/cpython/commit/8c6d9d7
- https://bugs.python.org/issue2987

Drive-by: use range() since xrange() doesn't exist on py3 and we're only
going to 16; clean up an invalid escape sequence.
