daemon: Allow builds to be repeated.
This makes it easy to detect non-deterministic builds. * nix/libstore/build.cc (DerivationGoal): Remove 'InodesSeen'; add 'curRound', 'nrRound', and 'prevInfos'. (DerivationGoal::inputsRealised): Initialize 'nrRound'. (NotDeterministic): New error type. (DerivationGoal::buildDone): Check whether we need to repeat. (DerivationGoal::startBuilder): Adjust message. (DerivationGoal::registerOutputs): Check whether we get the same result. * nix/libstore/globals.cc (Settings::get(const string & name, int def)): New method. * nix/libstore/globals.hh (Settings): Add it. * nix/libstore/store-api.hh (ValidPathInfo): Add operator ==. * nix/nix-daemon/nix-daemon.cc (performOp): Allow "build-repeat" for "untrusted" users.
