daemon: Client settings no longer override daemon settings.
Fixes <http://bugs.gnu.org/20217>. * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x161. * nix/nix-daemon/nix-daemon.cc (performOp): "build-max-jobs", "build-max-silent-time", and "build-cores" are no longer read upfront; instead, read them from the key/value list at the end. * nix/nix-daemon/guix-daemon.cc (main): Explicitly set 'settings.maxBuildJobs'. * guix/store.scm (%protocol-version): Bump to #x161. (set-build-options): #:max-build-jobs, #:max-silent-time, and #:build-cores now default to #f. Adjust handshake to new protocol. * tests/store.scm ("build-cores"): New test. * tests/guix-daemon.sh: Add test for default "build-cores" value.
