resolv: Introduce struct resolv_conf with extended resolver state
This change provides additional resolver configuration state which is not exposed through the _res ABI. It reuses the existing initstamp field in the supposedly-private part of _res. Some effort is undertaken to avoid memory safety issues introduced by applications which directly patch the _res object. With this commit, only the initstamp field is moved into struct resolv_conf. Additional members will be added later, eventually migrating the entire resolver configuration.
