 * Test that pthread_getspecific()
 *
 * It shall return the thread-specific data value associated with the given 'key'.  If no
 * thread-specific data value is associated with 'key, then the value NULL shall be returned.
 * It does not return any errors.
 *
 * Steps:
 * 1.  Create pthread_key_t object and do no specify a key accociated with this key
 * 2.  Call pthread_getspecific() and check that the value returns NULL.
