bpo-18533: Avoid RecursionError from repr() of recursive dictview (#4823)
dictview_repr(): Use a Py_ReprEnter() / Py_ReprLeave() pair to check for recursion, and produce "..." if so. test_recursive_repr(): Check for the string rather than a RecursionError. (Test cannot be any tighter as contents are implementation-dependent.) test_deeply_nested_repr(): Add new test, replacing the original test_recursive_repr(). It checks that a RecursionError is raised in the case of a non-recursive but deeply nested structure. (Very similar to what test_repr_deep() in test/test_dict.py does for a normal dict.) OrderedDictTests: Add new test case, to test behavior on OrderedDict instances containing their own values() or items().
