[sr-dev] moving is_int() to pv module

[Daniel-Constantin Mierla]

Hi Juha,

you added is_int() function to utils module, which has dependencies on 
curl and xml2 libraries. I think a better place would be pv module since 
it is actually working on pvs. Since it is new in 3.2, it should be 
moved before the major release -- if you think is ok, feel free to move 
it or if time is a constraint, I can do it.

Thanks,
Daniel
