Give both wrapper classes a ``__getnewargs__`` method, which causes the ZODB optimization to fail and create persistent references using the ``_p_oid`` alone. This happens to be the persistent oid of the wrapped object. This lets these objects to be persisted correctly, even though they are passed to the ZODB in a wrapped state.

Added failing tests for http://dev.plone.org/plone/ticket/10318. This shows an edge-case where AQ wrappers can be pickled using the specific combination of cPickle, pickle protocol one and a custom Pickler class with an ``inst_persistent_id`` hook. Unfortunately this is the exact combination used by ZODB3.

Fix the ``tp_name`` of the ImplicitAcquisitionWrapper and ExplicitAcquisitionWrapper to match their Python visible names and thus have a correct ``__name__``.

Expand the ``tp_name`` of our extension types to hold the fully qualified name. This ensures classes have their ``__module__`` set correctly.

Added support for method cache in Acquisition. Patch contributed by Yoshinori K. Okuji. See LP #486182.

add extra tests for the modified version of `PyObject_GetIter` used for iteration support (see https://bugs.launchpad.net/zope2/+bug/360761)

fix iteration proxying to pass `self` acquisition-wrapped into `__iter__` and `__getitem__` (fixes https://bugs.launchpad.net/zope2/+bug/360761)

first add [https://bugs.launchpad.net/zope2/+bug/360761/comments/7 the tests] kindly provided by Tres
