Workaround 'pos_*, [r]iter, dump never used' cppcheck style warnings (cord)

* cord/tests/cordtest.c [CPPCHECK] (CORD_iter, CORD_next,
CORD_pos_fetch, CORD_pos_to_cord, CORD_pos_to_index, CORD_pos_valid,
CORD_prev): Undefine (at the beginning of the file).
* cord/tests/cordtest.c [CPPCHECK] (test_basics): Call CORD_pos_to_cord,
CORD_pos_to_index, CORD_iter, CORD_riter, CORD_dump; add TODO item.
