daemon: Support multiplexed build output.
This allows clients to tell whether output comes from the daemon or, if it comes from a builder, from which builder it comes. The latter is particularly useful when MAX-BUILD-JOBS > 1. * nix/libstore/build.cc (DerivationGoal::tryBuildHook) (DerivationGoal::startBuilder): Print the child's PID in "@ build-started" traces. (DerivationGoal::handleChildOutput): Define 'prefix', pass it to 'writeToStderr'. * nix/libstore/globals.cc (Settings:Settings): Initialize 'multiplexedBuildOutput'. (Settings::update): Likewise. * nix/libstore/globals.hh (Settings)[multiplexedBuildOutput]: New field. Update 'printBuildTrace' documentation. * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0.163. * nix/nix-daemon/nix-daemon.cc (performOp) <wopSetOptions>: Special-case "multiplexed-build-output" and remove "use-ssh-substituter". * guix/store.scm (set-build-options): Add #:multiplexed-build-output? and honor it. (%protocol-version): Bump to #x163. * tests/store.scm ("multiplexed-build-output"): New test. fixlet
