substitute-binary: Implement `--substitute'.
This allows build outputs to be transparently downloaded from http://hydra.gnu.org, for example. * config-daemon.ac: Check for `gzip', `bzip2', and `xz'. * guix/config.scm.in (%gzip, %bzip2, %xz): New variable. * guix/scripts/substitute-binary.scm (fetch): Return SIZE as a second value. (<narinfo>): Change `url' to `uri'. (make-narinfo): Rename to... (narinfo-maker): ... this. Handle relative URLs. (fetch-narinfo): Adjust accordingly. (filtered-port, decompressed-port): New procedures. (guix-substitute-binary): Implement the `--substitute' case. * tests/store.scm ("substitute query"): Use (%store-prefix) instead of (getenv "NIX_STORE_DIR"). ("substitute"): New test.
