Maximilian Hils 9c873d63f4 py3++, multidict fixes
This commit improves Python 3 compatibility and fixes two multidict
issues:

 1. Headers.items(multi=True) now decodes fields
 2. MultiDict.clear(item) has been removed, as Python's
    MutableMapping already defines .clear() with different
    semantics. This is confusing for everyone who expects a
    dict-like object. `.pop("attr", None)` is not fantastic,
    but it's the Python way to do it.
