* Test that `str.format` checks the security for attributes that are accessed.

Part of PloneHotfix20170117.

This needs https://github.com/zopefoundation/AccessControl/pull/23
This was merged, but not released yet, so we add AccessControl to auto-checkout for now.

* AccessControl has a release, no need for auto-checkout anymore.

In functional doc tests you can apparently have a test case that has
no runTest method.  Until now the Testing package added a dummy
runTest method in that case, and set it to None.

But when this dummy runTest method gets called, you get an error:

  Error in test runTest (Testing.ZopeTestCase.ZopeTestCase.FunctionalTestCase)
  Traceback (most recent call last):
    File ".../lib/python2.7/unittest/case.py", line 329, in run
      testMethod()
  TypeError: 'NoneType' object is not callable

Simply importing Testing.ZopeTestCase.FunctionalTestCase in a new test
file may be enough to trigger this.

So this has something to do with the order in which tests are found.

I fixed it by making the dummy runTest method callable.

Add support for optional 'SameSite' cookie attribute

As described in the definition document by the ietf:
https://tools.ietf.org/html/draft-west-first-party-cookies-07

"The 'SameSite' attribute allows servers to assert that a cookie
ought not to be sent along with cross-site requests. This assertion
allows user agents to mitigate the risk of cross-origin information
leakage, and provides some protection against cross-site request
forgery attacks."
