Add fixture support in BOOST_DATA_TEST_CASE

[mikhail@…]

Now BOOST_DATA_TEST_CASE doesn't support test fixture at all. There is the ability to support this:

#define BOOST_FIXTURE_DATA_TEST_CASE_IMPL( arity, test_name, F, dataset, params )  \
struct test_name : public F {                                                      \
    template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>                            \
    static void test_method( BOOST_DATA_TEST_CASE_PARAMS( params ) )               \
    {                                                                              \
        BOOST_TEST_CHECKPOINT('"' << #test_name << "\" fixture entry.");           \
        test_name t;                                                               \
        BOOST_TEST_CHECKPOINT('"' << #test_name << "\" entry.");                   \
        BOOST_TEST_CONTEXT( ""                                                     \
            BOOST_PP_SEQ_FOR_EACH(BOOST_DATA_TEST_CONTEXT, _, params))             \
        t._impl(BOOST_PP_SEQ_ENUM(params));                                        \
        BOOST_TEST_CHECKPOINT('"' << #test_name << "\" exit.");                    \
    }                                                                              \
private:                                                                           \
    template<BOOST_PP_ENUM_PARAMS(arity, typename Arg)>                            \
    void _impl(BOOST_DATA_TEST_CASE_PARAMS( params ));                             \
};                                                                                 \
                                                                                   \
