introduced TECO_DEBUG_CLEANUP to mark destructors that should only be used for debug builds
* There is cleanup that is not strictly necessary, because it only frees memory
which is freed on program termination anyway.
* However, it helps to explicitly free everything for debugging memory leaks via Valgrind.
* The new macro reduces the number of #ifdef statements.
* On NDEBUG, the code of these functions will still be eliminated.
* If functions are referenced only from the destructor, there will be no unused function
warnings, even in NDEBUG.
