* 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.

Nixpkgs.
(url-fetch): New `mirrors' keyword parameter.
[builder]: Pass it.
* guix/build/download.scm (url-fetch): New `mirrors' keyword parameter.
[maybe-expand-mirrors]: New procedure.
[uri]: Use it.
* 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.
* guix/utils.scm (package-name->name+version): New procedure.
* guix-package.in (guix-package)[find-package]: Use it.
* tests/utils.scm ("package-name->name+version"): New test.

warn when Nixpkgs is not found.
* Makefile.am (AM_DISTCHECK_CONFIGURE_FLAGS): Remove `--with-nixpkgs'
flag.
* guix/utils.scm (%nixpkgs-directory): Use either the compile-time or
the run-time `NIXPKGS' environment variable.
* release.nix (jobs.tarball, jobs.build): Remove `--with-nixpkgs'
configure flag.
* README: Mark Nixpkgs as optional.
* distro/packages/databases.scm, distro/packages/guile.scm,
distro/packages/typesetting.scm: Change uses of `nixpkgs-derivation*'
to `nixpkgs-derivation', to avoid failing at compile-time.
* guix/ui.scm: New file.
* Makefile.am (MODULES): Add it.
* po/POTFILES.in: Add it.
* guix-build.in: Use it.
(_, N_, leave): Remove.
(guix-build): Use `with-error-handling' instead of the `guard' form.
* guix-download.in: Use it.
(_, N_, leave): Remove.
* guix/store.scm (add-indirect-root): New operation.
* guix-build.in (show-help): Document `--root'.
(%options): Add `--root'.
(guix-build)[register-root]: New procedure. Call it when `--root' is
passed.
* guix/build/utils.scm (substitute*): Remove special syntax for
list-of-files; instead, check whether FILE is `list?' at run time.
* distro/packages/base.scm (gcc-4.7, %binutils-static): Adjust
accordingly.
* guix/packages.scm (package-source-derivation): Add `system'
parameter. Pass it to METHOD.
(package-derivation)[expand-input]: Pass SYSTEM to
`package-derivation' and `package-source-derivation'.
* distro/packages/base.scm (package-with-bootstrap-guile)[boot]: Pass
SYSTEM to FETCH.
* guix/derivations.scm (imported-files): Call
`build-expression->derivation' with SYSTEM, not (%current-system).
(build-expression->derivation): Pass SYSTEM to `imported-modules' and
`compiled-modules'.
* guix/derivations.scm (%guile-for-build): Initialize to #f.
(imported-files, imported-modules, compiled-modules): Add `guile'
keyword parameter. Pass it down to `build-expression->derivation'.
(build-expression->derivation)[guile-drv]: New variable. Pass it as
the #:guile parameter for `imported-modules' and `compiled-modules'.
* tests/derivations.scm: Set %GUILE-FOR-BUILD to the derivation of
%BOOTSTRAP-GUILE.
* guix/derivations.scm (imported-files)[parent-dirs]: Move to...
(parent-directories): ... here. New procedure.
(compiled-modules): New procedure.
(build-expression->derivation): Use it.
* tests/derivations.scm ("build-expression->derivation with modules"):
New test.
* guix/packages.scm (package-derivation)[intern]: New procedure. Pass
#t as the `recursive?' argument, instead of #f.
[expand-input]: New procedure, with code formerly in the body.
Support inputs where the input is a procedure returning a file name or
an <origin>.
Use `expand-input' in the body.
* tests/packages.scm ("trivial with system-dependent input"): New test.
* guix/build/http.scm (open-connection-for-uri): New procedure.
(http-fetch): Use it. Pass the result as a #:port argument to
`http-get'.
Add hack to modify the `set-port-encoding!' binding in (web response).
* guix/ftp-client.scm (ftp-open): Add optional `port' parameter,
defaulting to 21. When calling `getaddrinfo', convert PORT to a
string and pass AI_NUMERICSERV when PORT is a number.
* distro/packages/base.scm (%guile-static, %guile-static-stripped): New
variables.
* distro/patches/guile-relocatable.patch: New file.
* Makefile.am (dist_patch_DATA): Add it.
* guix/packages.scm (%derivation-cache): Pass an initial size of 100.
(cache): Use `hashq-set!', and use a SYSTEM/DRV pair as the value.
(cached-derivation): Update accordingly.
* guix/build-system/gnu.scm (package-with-explicit-inputs): New `guile'
keyword parameter. Add it to P's arguments, and pass it in recursive
calls.
(gnu-build): New `guile' keyword parameter; new `guile-for-build'
variable. Pass it as the `#:guile-for-build' parameter of
`build-expression->derivation'.
* guix/build-system/trivial.scm (trivial-build): Likewise.
