resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984]
This commit enhances the stub resolver to reload the configuration in the per-thread _res object if the /etc/resolv.conf file has changed. The resolver checks whether the application has modified _res and will not overwrite the _res object in that case. The struct resolv_context mechanism is used to check the configuration file only once per name lookup.
