Resolver re-initialization NSS module

The nss_resinit is a module for the nsswitch subsystem which makes resolver3 reread /etc/resolv.conf when it is updated. In the traditional implementation of resolver3 it is initialized by the application once and never reread /etc/resolv.conf after that even if the file is updated. This module is useful especially when name servers in /etc/resolv.conf are changed frequently as seen in mobile environment.
