Allowing log-capturing only for user apps
Fixed loop, when closing file on disc device

And developer could end-up with an infinite loop, when tries to close the
file and device got disconnected meantime.
Upgraded the level of device-logs processing

Main changes:
 * launcher-service can associate any class to communicate with the
   spawned process on the device
 * console-logger and slog2info-logger distribute logs via events
   (not printing them directly into trace-listeners as before)
 * Targets class is responsible for receiving and filtering all the logs
   (slog2 logs are limited to the processes, where console-logs are monitored)
 * added advanced parsing of slog2 logs to extract info about the process-id
   as well as buffer-set and message
