The only sporadically used CIO_DEBUG messages are replaced by ordinary
CIO_MSG_EVENT messages. The CIO_MSG_EVENT messages debug levels are
consolidated.

Determines whether information on found devices and sensed device
characteristics should be shown during startup or when new devices are
found, i. e. messages of the types "Detected device 0.0.4711 on subchannel
