[PATCH 1/2] rangeset: add RANGESETF_no_print flag

[Oleksandr Andrushchenko <andr2000@xxxxxxxxx>]

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@xxxxxxxx>

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.
