- [Bug fix] ros2 topic echo message truncation

Full list of backported PRs available at https://github.com/ros2/ros2/issues/563#issue-350960812

The docker images under [osrf/ros2](https://hub.docker.com/r/osrf/ros2/tags/) include the last versions of these packages.

Note for Windows users: The new version of Visual Studio (2017 v 15.8, MSVC 19.15) seems to have a compiler bug preventing from building some packages ([details](https://github.com/osrf/osrf_testing_tools_cpp/issues/15)). If you're building from source, make sure to use an older version of VS2017 (we used MSVC 19.12 to generate the binaries of this release).

Thanks to all contributors who have helped make this sync happen!
