rcl: Common functionality ROS lifecycle

rcl_lifecycle provides a pure C implementation of the ROS concept of lifecycle. It builds on top of the implementation of topics and services in rcl.

rcl_lifecycle consists of functions and structs for the following ROS lifecycle entities:

• Lifecycle states

• Lifecycle transitions

• Lifecycle state machine

• Lifecycle triggers

Some useful abstractions:

• Return codes and other types

  • rcl_lifecycle/data_types.h
