Description

The patch is from python/cpython#12211. It's not
merged into official CPython 3.4 for timing reasons.

TLS functionality tested with the following script:

    try:
        import urllib.request as urllib_request
    except ImportError:
        import urllib2 as urllib_request

    h = urllib_request.urlopen('https://httpbin.org/ip')
    print(h.read().decode('utf-8'))

Seems fine to me. Python 3.4 should anyway be depreciated in macports.
