bpo-29204: Emit warnings for already deprecated ElementTree features. (#773)

Browse source 
Element.getiterator() and the html parameter of XMLParser() were
deprecated only in the documentation (since Python 3.2 and 3.4 correspondintly).
Now using them emits a deprecation warning.

* Don’t need check_warnings any more.
