* doc/guix.texi (Invoking guix pack): Add xrefs to "guix publish", "guix
copy", and "guix archive".
(Invoking guix archive): Add xref to "guix pack".

Previously we were looking at the load of the past 5 minutes, which
means that, after a build, we could end up waiting for 5 minutes for
that metric to be low enough.

* guix/scripts/offload.scm (machine-load): Compute RAW based on ONE, not
FIVE.

* gnu/build/ruby-build-system.scm: Import (ice-9 rdelim).

Follow-up to d9df4bf0.

* gnu/packages/samba.scm (talloc): Update to 2.1.11.
[arguments]: Run all tests.  Use INVOKE.

* gnu/packages/samba.scm (iniparser): Update to 4.1.
[arguments]: Update library SONAME.
[home-page]: Abandon outdated home page with no mention of version 4.

* gnu/packages/samba.scm (iniparser)[arguments]: Simplify ‘install’ phase by
replacing COPY-FILE with INSTALL-FILE.

* gnu/packages/samba.scm (iniparser)[arguments]: Use #:make-flags to set
‘CC’ instead of patching the Makefile.  Remove fruitless SYMLINK call.

* gnu/packages/samba.scm (iniparser)[arguments]: Install documentation to
‘/share/doc/iniparser’ instead of ‘/share/doc’.

* gnu/packages/ccache.scm (ccache): Update to 3.3.5.
[arguments]: Don't substitute ‘which’ in ‘setup-tests’ phase.
Add new ‘munge-failing-test’ phase to make test suite pass.

* gnu/packages/emacs.scm (emacs-json-mode): New public variable.

* gnu/packages/patches/emacs-json-reformat-fix-tests.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add this.
* gnu/packages/emacs.scm (emacs-json-reformat): New variable.

* gnu/packages/haskell.scm (ghc-hmatrix-special): Update to 0.4.0.1.

* gnu/packages/haskell.scm (ghc-hmatrix-gsl-stats): Update to 0.4.1.7.

* gnu/packages/haskell.scm (ghc-hmatrix-gsl): Update to 0.18.0.1.

* gnu/packages/haskell.scm (ghc-hmatrix): Update to 0.18.1.0.

* gnu/packages/haskell.scm (ghc-juicypixels): Update to 3.2.9.3.

* gnu/packages/haskell.scm (ghc-iproute)[home-page]: Use HTTPS.

* gnu/packages/haskell.scm (ghc-iproute): Update to 1.7.1.

* gnu/packages/xiph.scm (opusfile): Update to 0.9.

* gnu/packages/xiph.org (libogg, libvorbis, libtheora, ao, flac)
(vorbis-tools, opusfile, icecast)[home-page]: Use HTTPS.

* gnu/packages/linux.scm (ltrace, libnl, pflask, acpi, module-init-tools)
(snapscreenshot)[home-page]: Use HTTPS.

* gnu/packages/tls.scm (openssl, p11-kit, python-acme)[home-page]: Use
HTTPS instead of HTTP, irony.

* gnu/packages/geo.scm (geos): Update to 3.6.2.

* gnu/packages/gps.scm (gpsbabel)[source]: Remove unused files in a snippet.
[license]: Add expat.

* gnu/packages/gps.scm (gpsbabel)[home-page]: Use HTTPS.

* gnu/packages/libedit.scm (libedit): Update to 20170329-3.1.
[arguments]: Remove deprecated ‘--enable-widec’ from #:configure-flags.

* gnu/packages/libedit.scm (libedit)[home-page]: Use HTTPS.

Now that the build system does wrapping automatically, it can be removed from
the packages that do it manually.

* gnu/packages/databases.scm (es-dump-restore)[arguments]: Remove #:phases.
* gnu/packages/ruby.scm (ruby-redcloth)[arguments]: Remove #:phases.
  (ruby-httpclient)[arguments]: Remove 'wrap-bin-httpclient from the modified
  phases.

Wrap files in bin/ and sbin/ with the location of the gem itself and the
location of any other gems in use (GEM_PATH). This ensures that the bin files
will run with the right environment when executed.

It does however mean that native-inputs will also get wrapped up in any
binaries, which is not good, as it increases the size of the closure, and
risks this code being used at runtime.

* guix/build/ruby-build-system.scm (wrap): New procedure.
  (%standard-phases): Add the wrap phase.

A modified copy of wrap-program from (guix build utils). The wrap-program
procedure doesn't work well for Ruby scripts, as it breaks using the -S flag
with ruby to execute the script, as when -S is passed to ruby, it expects the
script on the PATH to use ruby in the shebang, and not bash.

Therefore, to wrap the program, but keep the shebang as ruby, wrap it with a
ruby script instead.

wrap-ruby-program uses .real/foo rather than .foo-real, as this might be
neater. This procedure also includes a call to Gem.clear_paths to make it
possible to set the GEM_PATH through this method, and for it to take effect.

* gnu/build/ruby-build-system.scm (wrap-ruby-program): New procedure.

* guix/build/ruby-build-system.scm (install): Install gems to the vendor
  directory, rather than the GEM_HOME. The vendor directory does not include
  the version of ruby used to install the gem in the path, which makes it
  easier to add it to the GEM_PATH for all versions of ruby to use.
  (gem-home): Remove procedure.
* gnu/packages/ruby.scm (ruby, ruby-2.1)[native-search-paths]: Switch to
  lib/ruby/vendor_ruby.
  (ruby-1.8)[native-search-paths]: Remove native-search-paths.
  (gem-directory): Remove procedure.
  (ruby-ansi, ruby-ae)[arguments]: Remove use of gem-directory.
  (ruby-metaclass, ruby-instantiator, ruby-introspection, ruby-mocha,
  ruby-nokogiri, ruby-minitest-tu-shim, ruby-redcloth)[arguments]: Remove use
  of gem-home.
  (ruby-git, ruby-httpclient)[arguments]: Remove use of GEM_HOME.
* gnu/packages/databases.scm (es-dump-restore)[arguments]: Remove use of
  GEM_HOME.

* gnu/packages/algebra.scm (arb): Update to 2.12.0.

* gnu/packages/algebra.scm (pari-gp): Update to 2.9.4.

* doc/guix.texi (Web Services): The body of an NGINX-LOCATION-CONFIGURATION
is a list of strings and not a string.

OpenSSL and zlib are referred to by the built package, so we make them
regular inputs.

This is a followup to commit e8b40974.

* gnu/packages/cpp.scm (rct)[native-inputs]: Move openssl and zlib to ...
[inputs]: ... new field.

* gnu/packages/cpp.scm (rct): New variable.

* gnu/packages/flashing-tools.scm (flashrom): Update to 1.0.

* gnu/packages/flashing-tools.scm (flashrom)[home-page]: Use HTTPS.

This follows up commit 7641266b.

* gnu/packages/mpd.scm: Don't #:use-module (gnu packages gcc).

* gnu/packages/mpd.scm (libmpdclient, mpd, mpd-mpc, ncmpc)[home-page]: Use
HTTPS.
