Bugfix/confirmed handlers empty service request (#885)

* Added reject in all confirmed service handlers, except GetEventInformation, when confirmed services with zero length occur which rejects with required parameters are missing message.

* Refactored errno use in service using debug_perror. Changed debug_perror usage to debug_fprintf. 

* Updated file and function headers in basic/service modules.

* Changed NDPU priority on confirmed messages to use requested NDPU priority.

* Renamed debug_aprintf to debug_printf_stdout for clarity.

* Convert most debug_fprintf usage to debug_print to reduce text bloat in AVR build
