conversion code.

* guix/import/utils.scm: ... to here.
(license->symbol): New procedure.
* guix/gexp.scm (lower-object): New procedure.
(lower-inputs, lower-references, gexp->sexp): Use it.
* tests/gexp.scm ("lower-object"): New test.
* doc/guix.texi (G-Expressions): Document it.
* guix/scripts/package.scm (show-help): Add help text for --install-from-file
option.
(%options): Add --install-from-file option.
* tests/guix-package.sh: Test it.
* doc/guix.texi ("invoking guix package"): Document it.
* doc/package-hello.scm: New file.

This removes all I/O, which obviously makes things faster.
* guix/scripts/size.scm (file-size, store-item-exists?): Remove.
(query-path-info*): New procedure.
(file-size*): Rename to...
(file-size): ... this; adjust caller. Use 'query-path-info*' instead of
'file-size'.
On systems with a glibc prior to 2.14, the 'setns' function is not available.
Thanks to Eric Bavier for reporting the issue.
* guix/build/syscalls.scm (setns): Wrap with 'false-if-exception'.
Reported by Eric Dvorsak <eric@dvorsak.fr> on #guix.
* guix/scripts/import/elpa.scm (%default-options): Remove redundant
quote which led to an error if --archive option was not specified.
Based on discussions with Rohan Prinja <rohan.prinja@gmail.com>.
* guix/build/syscalls.scm (<interface>): New record type.
(write-interface, values->interface, unfold-interface-list,
network-interfaces, free-ifaddrs): New procedures.
(ifaddrs): New C struct.
(%struct-ifaddrs-type, %sizeof-ifaddrs): New macros.
* tests/syscalls.scm ("network-interfaces returns one or more interfaces",
"network-interfaces returns \"lo\""): New tests.
* guix/build/syscalls.scm (alignof*, align): New macros.
(write-types, read-types): Use 'align' to compute the actual offset to
read/write a value of TYPE0.
* guix/build/syscalls.scm (PF_PACKET, AF_PACKET): New variables.
(read-socket-address): Make 'index' optional. Return (vector FAMILY) when
FAMILY is neither AF_INET nor AF_INET6.
Previously, before replying to a /nar/* request, 'guix publish' would first
build up the whole nar into memory (as a consequence of
<http://bugs.gnu.org/21093>), which obviously doesn't scale.
* guix/scripts/publish.scm (render-nar): Return STORE-PATH instead of a
procedure that calls 'write-file'.
(sans-content-length): New procedure.
(http-write): For 'x-nix-archive', don't call '%http-write'. Instead, call
'write-file' right from here, using BODY as the file name.
* guix/scripts/publish.scm (%http-write): New variable.
(http-write): New procedure.
(concurrent-http-server): New variable.
(run-publish-server): Use it.
* guix/build/syscalls.scm (read-types): Add RETURN and VALUES parameters.
(define-c-struct): Add WRAP-FIELDS parameter and pass it to 'read-types'.
(sockaddr-in, sockaddr-in6): Add first argument that uses
'make-socket-address'.
(read-socket-address): Remove 'match' on the result of 'read-sockaddr-in'
and 'read-sockaddr-in6'.
* gnu/system.scm (<operating-system>)[kernel-arguments]: New field.
(operating-system-grub.cfg): Honor it.
(operating-system-parameters-file): Add 'kernel-arguments' to the parameters
file.
* guix/scripts/system.scm (previous-grub-entries)[system->grub-entry]: Read
the 'kernel-arguments' field of the parameters file, when available.
* gnu/system/vm.scm (system-qemu-image/shared-store-script):
Use (operating-system-kernel-arguments os) in '-append'.
* doc/guix.texi (operating-system Reference): Document it.
* guix/build-system/gnu.scm (gnu-build, gnu-cross-build): Accept #:build
keyword argument. Pass it to 'gnu-build' on the build side.
* guix/build/gnu-build-system.scm (configure): Accept #:build keyword
argument. Unless it is false, pass --build to configure.
* guix/scripts/substitute.scm (display-narinfo-data,
process-query, process-substitution): New procedures. Code moved from...
(guix-substitute): ... here. Use them.
* guix/scripts/substitute.scm (or*): New macro.
(%cache-url): Honor "untrusted-substitute-urls".
* guix/tests.scm (%test-substitute-urls): New variable.
(open-connection-for-tests): Use it.
* tests/derivations.scm ("derivation-prerequisites-to-build and substitutes",
"derivation-prerequisites-to-build and substitutes, non-substitutable
build", "derivation-prerequisites-to-build and substitutes, local build"):
Pass it to 'set-build-options'.
* tests/guix-daemon.sh: Likewise.
* tests/store.scm ("substitute query, alternating URLs"): New test.
("substitute query", "substitute", "substitute + build-things with output
path", "substitute, corrupt output hash", "substitute --fallback"): Pass
#:substitute-urls to 'set-build-options'.
This ensures that switching between different substitute servers doesn't lead
to a polluted narinfo cache.
* guix/scripts/substitute.scm (narinfo-cache-file): Add 'cache-url'
parameter. Add the base32 of CACHE-URL as a sub-directory under
%NARINFO-CACHE-DIRECTORY. Update callers.
(cached-narinfo): Likewise. Call 'mkdir-p' on the dirname of the cache
file. Update callers.
(remove-expired-cached-narinfos): Add 'directory' parameter and use it
instead of %NARINFO-CACHE-DIRECTORY.
(narinfo-cache-directories): New procedure.
(maybe-remove-expired-cached-narinfo): Call 'remove-expired-cached-narinfos'
for each item returned by 'narinfo-cache-directories'.
* guix/scripts/substitute.scm (<cache>): Rename to...
(<cache-info>): ... this.
(open-cache): Rename to...
(download-cache-info): ... this. Return a <cache-info> or #f.
(open-cache*): Remove.
(cache-narinfo!): Take a URL instead of a <cache> as the first parameter.
(fetch-narinfos): Likewise. Call 'download-cache-info'. Remove use of
'force'.
