LP #1155760.

Give up on protecting against segfaults in aq_* functions, when we encounter __parent__ circles with more than one intermediate object.

Raise `RuntimeError: Recursion detected in acquisition wrapper` if an object with a `__parent__` pointer points to a wrapper that in turn points to the original object.

Fix the triple parent test - we actually get reasonable results now, but also some infinite recursion on non-existant attributes

Avoid an infinite recursion in parent parent circles, if they are no longer wrapped in all cases like with ExtensionClass 4.0

Fixed a segfault on 64bit platforms when providing the `explicit` argument to the aq_acquire method of an Acquisition wrapper. Thx to LP #675064 for the hint to the solution. The code passed an int instead of a pointer into a function.
