Run clang-tidy 7.0 with `-checks='-*,modernize-use-using' -fix` against TU-s of all tests. Manually refactor numerous typedef-s - where missed by modernize-use-using check, not uncommon - in code snippets in comments Outcome is that searching for lower-case whole word typedef in sources of all the tests should return no matches.
