Convert a number of destructors to default synthesized functions. Try to inline a few instances into the header. It should be possible to inline all of them, however, gcc seems to emit a number of warnings. Furthermore, some of the destructors are pure-virtualed, but provide an implementation. Placing the definition into the header causes ODR violations.
