It adds a new operation, cmdAddToStoreNar, that does the same thing as the corresponding nix-daemon operation, i.e. call addToStore(). This replaces cmdImportPaths, which has the major issue that it sends the NAR first and the store path second, thus requiring us to store the incoming NAR either in memory or on disk until we decide what to do with it. For example, this reduces the memory usage of $ nix copy --to 'ssh://localhost?remote-store=/tmp/nix' /nix/store/95cwv4q54dc6giaqv6q6p4r02ia2km35-blender-2.79 from 267 MiB to 12 MiB. Probably fixes #1988.
