- FairMQ: add possibility to poll on multiple channels. - FairMQ: include command channel when polling on blocking calls (for unblocking without termination). - FairMQ: move signal handler inside of FairMQDevice class (call FairMQDevice::CatchSignals() in the main function). - FairMQ: add 'bool CheckCurrentState(statename)' (instead of 'GetCurrentState() == statename' that cannot be thread safe). - FairMQDevice: add 'InteractiveStateLoop()' method that can be used to change states from the command line. - FairMQDevice: add automatic transition to IDLE state if Run() exits without an external event. - FairMQDevice: implement device reset. - FairMQDevice: use unordered_map for device channels. - FairMQChannel: improve address validation for channels. - FairMQChannel: add ExpectsAnotherPart() method to check if another msg part is expected (old approach still works). - FairMQ: remove invalid transition from the run files. - FairMQFileSink: disable ROOT termination signal handler. - Tutorial3: spawn xterm windows from start scripts without overlapping for better visibility. - FairMQ Examples: update protobuf test and move its files to a common directory. - FairMQStateMachine: improve feedback on invalid transitions (more readable).
