implemented freeCnf() module interface & fixed some mem leaks

The interface was actually not present in older versions, even though some modules
already used it. The implementation was now done, and not in 6.3/6.4
because the resulting memory leak was ultra-slim and the new interface
handling has some potential to seriously break things. Not the kind of
 thing you want to add in late beta state, if avoidable.
