C++20 revised the definition of what it means to be an iterator. While all _Cpp17InputIterators_ satisfy `std::input_iterator`, the reverse isn't true. D100271 introduces a new test adaptor to accommodate this new definition (`cpp20_input_iterator`). In order to help readers immediately distinguish which input iterator adaptor is _Cpp17InputIterator_, the current `input_iterator` adaptor has been prefixed with `cpp17_`.
