daemon: Remove ‘foreach’ and ‘foreach_reverse’

Browse source 
‘foreach_reverse’ is not used anywhere

* nix/libutil/util.hh (foreach, foreach_reverse): Remove.
* nix/libstore/build.cc (addToWeakGoals): Use ‘std::none_of’ instead of macro ‘foreach’.
(Goal::waiteeDone, Goal::amDone, UserLock::acquire, rewriteHashes,
DerivationGoal::addWantedOutputs, DerivationGoal::haveDerivation,
DerivationGoal::outputsSubstituted, DerivationGoal::repairClosure,
DerivationGoal::inputsRealised, DerivationGoal::tryToBuild,
DerivationGoal::buildDone, DerivationGoal::tryBuildHook,
DerivationGoal::startBuilder, DerivationGoal::runChild,
parseReferenceSpecifiers, DerivationGoal::registerOutputs,
DerivationGoal::checkPathValidity, SubstitutionGoal::tryNext,
SubstitutionGoal::referencesValid, Worker::removeGoal,
Worker::childTerminated, Worker::run, Worker::waitForInput): Use range-based
‘for’ instead of macro ‘foreach’.
* nix/libstore/derivations.cc (writeDerivation, unparseDerivation,
hashDerivationModulo): Likewise.
* nix/libstore/gc.cc (addAdditionalRoots, LocalStore::deletePathRecursive,
LocalStore::canReachRoot, LocalStore::collectGarbage): Likewise.
* nix/libstore/globals.cc (Settings::pack): Likewise.
* nix/libstore/local-store.cc (checkDerivationOutputs, queryValidPaths,
querySubstitutablePaths, querySubstitutablePathInfos, registerValidPaths, verifyStore,
verifyPath): Likewise.
* nix/libstore/misc.cc (computeFSClosure, dfsVisit, topoSortPaths): Likewise.
* nix/libstore/optimise-store.cc (LocalStore::optimisePath_, LocalStore::optimiseStore): Likewise.
* nix/libstore/pathlocks.cc (PathLocks::lockPaths, PathLocks::~PathLocks): Likewise.
* nix/libstore/references.cc (search, scanForReferences): Likewise.
* nix/libstore/store-api.cc (checkStoreName, computeStorePathForText,
StoreAPI::makeValidityRegistration, showPaths, readStorePaths): Likewise.
* nix/libutil/serialise.cc (writeStrings): Likewise.
* nix/libutil/util.cc (concatStringsSep): Likewise.
* nix/nix-daemon/nix-daemon.cc (performOp): Likewise.
