Work for test refactoring.

There are a few major areas in this change.

* CMake options are now located in a common cmake/NNGOptions.cmake
  file.  This should make it easier for folks to figure out what
  the options are, and how they are used.

* Tests are now scoped with their directory name, which should
  avoid possible name collisions with test names.

* A number of tests have been either moved or incorporated into
  the newer testutil/acutest framework.  We are moving away from
  my old c-convey framework to something easier to debug.

* We use CMake directories a bit more extensively leading to a much
  cleaner CMake structure.  It's not complete, but a big step in the
  right direction, and a preview of future work.

* Tests are now run with verbose flags, so we get more test results
  in the CI/CD logs.
