Enable testloops for nosetests

Ensure nosetests sees all tests in the tests[] tuples. This requires
some name changes because nosetests thinks all function names containing
"test" are tests. (A "not a test" docorator would be an alternative, but
that would require some try/except magic to avoid a dependency on nose.)

To avoid nosetests thinks the functions are a test,
- rename setup_all_tests() to setup_all_loops()
- rename regex_test() to _regex_test() (in test-regex_matches.py)

Also add the module_name as parameter to setup_all_loops and always run
it (not only if __name__ == '__main__').

Known issue: nosetests errors out with
    ValueError: no such test method in <class ...>: stub_test
when trying to run a single test generated out of tests[].
(debugging hint: stub_test is the name used in setup_test_loop().)
But that's still an improvement over not seeing those tests at all ;-)
