  (Top, Introduction): Mention "for the GNU system".

These new binaries are built with the `--with-lib-path' and
`--with-local-prefix' flags, respectively, as introduced in commit
01d45404.

* distro/packages/bootstrap.scm (%bootstrap-coreutils&co,
  %bootstrap-glibc): Update URL.
  (%bootstrap-binutils, %bootstrap-gcc): Update URL and hashes.
* build-aux/download.scm (file-name->uri): Update URL.

This fixes impurities with non-chroot builds on LFS-style distros.

* distro/packages/base.scm (binutils): Pass `--with-lib-path'.
  (gcc-4.7): Pass `--with-local-prefix'.
* distro/packages/make-bootstrap.scm (%binutils-static): Pass
  `--with-lib-path'.

* guix-download.in (http-fetch, ftp-fetch): Remove.
  (fetch-and-store): Replace `uri' parameter with `name', for the output
  file name.  Redirect the output of `fetch' to the error port.
  (guix-download): Call `url-fetch' for all URI schemes except `file'.
  Handle PATH equal to #f.
* guix/download.scm: Export `%mirrors'.
* tests/guix-download.sh: Change erroneous URL, because URLs at
  example.com are all valid redirections.

  a `file' URI scheme is used.
* Makefile.am (AM_TESTS_ENVIRONMENT): New variable.

  #:guile %BOOTSTRAP-GUILE.

* tests/derivations.scm ("build-expression->derivation for fixed-output
  derivation"): Remove test.  It is redundant with that in builders.scm,
  and doesn't work out of the box with the statically-linked
  %BOOTSTRAP-GUILE.

* Makefile.am (DOWNLOAD_FILE): Add $(top_builddir) to the search path,
  since that's where guix/config.scm is.
  (.scm.go): Likewise.

* distro/packages/base.scm (glibc): Apply `glibc-no-ld-so-cache.patch'.
  (glibc-final): Inherit GLIBC's inputs.

* distro/packages/bootstrap.scm: Likewise
  (bootstrap-origin): Remove references to `http-fetch' and
  `ftp-fetch'.
* guix.scm (%public-modules): Remove `http' and `ftp'; add `download'.

* guix/download.scm, guix/build/download.scm: New files.
* Makefile.am (MODULES): Add them.
* tests/builders.scm ("url-fetch"): New test.
* distro/packages/bootstrap.scm (bootstrap-origin): Support
  `url-fetch'.
* guix/snix.scm (snix-derivation->guix-package): Use `url-fetch' instead
  of `http-fetch'.

* guix/utils.scm (bytevector-quintet-ref, bytevector-quintet-ref-right,

* tests/packages.scm (%bootstrap-inputs): Remove.
  ("GNU Hello"): Rename to...
  ("GNU Make, bootstrap"): ... this.  Build GNU-MAKE-BOOT0 instead of
  HELLO.

* guix/build/http.scm (http-fetch): Emit message indicating the
  download.

* guix/build/http.scm (http-fetch): Check RESP's code; error out when
  it's not 200.

* guix/derivations.scm (build-expression->derivation)[source-path]: New
  procedure.
  [builder]: Pass only sources as references.  This fixes a bug whereby
  changing a fixed-output drv referred to by a builder would cause the
  builder's hash to change, thereby leading to a full rebuild.
* tests/derivations.scm ("build-expression->derivation with a
  fixed-output input"): New test.

* tests/derivations.scm ("fixed-output derivation"): Add comment that
  the reference to BUILDER is optional.

  RESPONSE's code is not 200.

* tests/guix-download.sh: New file.

  @direntry for "Invoking guix-package".
  (Package Management): New chapter.

  and SUB-DRV when NAME contains #\:.

* tests/guix-package.sh (profile): Add test.
