Saleem Abdulrasool 64ba7d5be8 modernize: use default method synthesis
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.
