This fixes #428 by using a similar approach to ros2/rmw_cyclonedds#228

It also addresses #219

@ivanpauno I think builds have failed due to #382

rcl failures seem to be a flake because of another node running in the system.

This is on the Foxy patch release board, though I'd rather not backport API changes to publicly accessible headers.

@ivanpauno Can you take a look to see if this can be backported in without the changes to API?

This is on the Foxy patch release board, though I'd rather not backport API changes to publicly accessible headers.

Though Typesupport.hpp and Typesupport_impl.hpp are public headers, nobody uses them.
I don't think this can be fixed without the API changes, IMO it's worth backporting (it's fixing several leaks + potential undefined behavior).

Bumping this to a future Dashing patch release pending an agreement on the backport discussion above. Dashing will follow Foxy's lead.
