        * glib/gdataset.c:
        moved G_DATALIST_*_POINTER() macros here, because proper use requires
        the global g_dataset_global mutex to be acquired.
        g_datalist_id_get_data():
        g_datalist_unset_flags():
        g_datalist_set_flags(): properly acquire and release dataset mutex.

        * glib/gdatasetprivate.h: implement G_DATALIST_GET_FLAGS() via atomic
        pointer access to account for memory barriers. moved all other macros.
