It appears there is little code to be factored-out in gaih_inet(),
which is the workhorse. There several attempts to parse
a hostname as numeric and the flag prevents from going
further.
Yet another issue I can see, is that the factored out code
would have to be public (?) to be available to NSS module.
Now I can see there is __inet6_scopeid__pton(). I'll try it but I am
afraid probably it won't be visible in the NSS module.
