Provide an extension trait message_to_string that allows client code
to call ASSERT_MESSAGE with their own string types.

Also provide a default extension trait that accepts std::ostream
messages.

This allows to execute the same test with different parameters and
treats each execution as an own test. The change consists of two parts,
the TestCaller can now handle any callable which also makes it easy to
generate programatically more complex test cases as well as the new
CPPUNIT_TEST_PARAMETERIZED macro. That macro takes the test name as well
as an iteratable, e.g. std::initializer_list.

An example for this usage is:

class SimpleTest : public CppUnit::TestFixture
{
public:
    CPPUNIT_TEST_SUITE(SimpleTest);
    CPPUNIT_TEST_PARAMETERIZED(test, {1, 2, 3, 4});
    CPPUNIT_TEST_SUITE_END();

    void test(int i)
    {
        CPPUNIT_ASSERT(i < 5);
    }
};

which will execute test 4 times with the values 1 to 4.

The asserter now has special handling to convert the enum class to a
std::string. This does not work without some template magic as enum
class has no implicit conversion to int.
