Consolidate calc_checksum_bytes_internal routine

Browse Source 
Now that the deprecated `get_checksum{,_bytes}` routines are removed,
the checksum is always computed with ignored data after the first '#',
i.e. the boolean parameter `exclude_hash` is not needed anymore and
the functionality can be consolidated into `calc_checksum_bytes`.
