    rangeset: add RANGESETF_no_print flag
    
    There are range sets which should not be printed, so introduce a flag
    which allows marking those as such. Implement relevant logic to skip
    such entries while printing.
    
    While at it also simplify the definition of the flags by directly
    defining those without helpers.
