Merge pull request #67 from pal-robotics/issue-65

Honor unspecified vel/acc in ROS message. Fix #65.
Refactor how the currrent trajectory is stored.

- Handle concurrency in the current trajectory between rt and non-rt threads
  using the simpler RealtimeBox instead of the RealtimeBuffer, because our
  usecase does not fit well the non-rt->writes / rt->reads semantics.

- As a consequence we no longer need to store the msg_trajectory member, but
  only the hold_trajectory, which must still be preallocated.
