dds-topology: Add possibility to specify arguments for tasks in the topology.
- Updated Release Notes
- fixed minor warnings of unused variables in protocol tests.
Thanks to new do_execv, DDS learned now how to expand given user tasks commands with arguments given as a single string. (in the Topology->Task->exec parameter).
The new do_execv takes a command and its arguments as a single string and expands it to a command and arguments array to pass it further to execv.
