py3: add compatibilty functions for urllib2.Request.get_{type|host|selector}()

urllib2.Request i.e. urllib.request.Request in Py3 had few functions named
get_host(), get_type() and get_selector() which were depreceated in Py3.3
and got removed in Py3.4. This patch adds compatibility functions in
pycompat.py for the same.
