bpo-37421: urllib.request tests call urlcleanup() (GH-14529)
urllib.request tests now call urlcleanup() to remove temporary files created by urlretrieve() tests and to clear the _opener global variable set by urlopen() and functions calling indirectly urlopen(). regrtest now checks if urllib.request._url_tempfiles and urllib.request._opener are changed by tests.
