    Add unit test suites with initial successful dummy test (#781978)
    
    Now 'make check' will additionally build and run the test suites in the
    ./tests directory.  Add initial always successful dummy test suite.
    This is done using Automake support for testing.

    ./tests/Makefile.am takes some influence from the same file in the
    minimal-gtest-autotools template project.
