* 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
