Subject: This is the test program for listing controller variables

This is the test program for new internal functions:

    int cgroup_get_value_name_count(struct cgroup_controller *controller)
    char *cgroup_get_value_name(struct cgroup_controller *controller, int     index)

The program display the variables of input controllers.
