Fix iteration of BTrees.items() in pure-python; and 3.6 support

Also fix ``list(proxy_btree.items())`` (or a list comprehension of the
same) in Python 3, which wants the ``__len__`` for a hint.

This is a central place to make sure these all behave consistently.

Fixes #20

Also drop pypy3

As a 3.2 implementation, it's not supported by pip anymore. There is a
much more recent version, 3.5-beta, but it's not on Travis yet. The
3.3-alpha which is on Travis is a dead end.
