copyStorePath() now pipes the output of srcStore->narFromPath() directly into dstStore->addToStore(). The sink used by the former is converted into a source usable by the latter using boost::coroutine2. This is based on [1]. This reduces the maximum resident size of $ nix build --store ~/my-nix/ /nix/store/b0zlxla7dmy1iwc3g459rjznx59797xy-binutils-2.28.1 --substituters file:///tmp/binary-cache-xz/ --no-require-sigs from 418592 KiB to 53416 KiB. (The previous commit also reduced the runtime from ~4.2s to ~3.4s, not sure why.) A further improvement will be to download files into a Sink.
