bitmap_size() is a pretty generic name and one may want to use it for a generic bitmap API function. At the same time, its logic is not "generic", i.e. it's not just `nbits -> size of bitmap in bytes` converter as it would be expected from its name. Add the prefix 'idset_' used throughout the file where the function resides.
