spelling.

This improves parallelism when 'max-jobs' is large.

* src/cuirass/base.scm (build-packages): Rewrite to pass the complete
list of derivations to 'build-derivations' at once.  Handle multiple outputs.
* src/schema.sql (Builds): Make "output" part of the primary key.

Co-authored-by: Mathieu Lirzin <mthl@gnu.org>

* src/cuirass/base.scm (fetch-repository): Remove 'file-exists?' call
before 'mkdir-p'.

* src/cuirass/base.scm (process-specs): Systematically call
'set-build-options'.  Pass #:keep-going? #t.

This fixes an issue in the database, where rows from the 'Evaluations' table
were having an "#f" value instead of a valid reference to their corresponding
specification.

* bin/evaluate.in (main): Use specification #:name instead of obsolete #:id.

* src/cuirass/base.scm (set-guix-package-path!): Parse colon separated
directories in load-path.

.

* src/cuirass/base.scm (fetch-repository): Return #f when 'git clone' fails.
(process-specs): Test if commit is not #f before using its value.

* build-aux/guix.scm (%aux-dir): New variable.  Use it.

* build-aux/guix.scm (spec+package-list): New procedure.  Use it.

* Makefile.am (.version): Remove target.
(EXTRA_DIST): Adapt.
(BUILT_SOURCES): Likewise.
* build-aux/guix.scm (git-version-gen): Call 'git-version-gen' with
'.tarball-version'.
* .gitignore: Update.

* doc/cuirass.texi (Contributing): Use "bug-cuirass@framalistes.org" email
address.

This fixes the issue of having multiple identical derivations associated with
an evaluation as reported by Ludovic Courtès <ludo@gnu.org> at
<https://lists.gnu.org/archive/html/guix-devel/2017-01/msg00109.html>.

* src/cuirass/database.scm (db-add-derivation): Ignore if JOB is already
present in DB.

This was mistakenly added in commit 05e5495e.

* Makefile.am: Declare GPLv3+ instead of GPLv2+.
* configure.ac: Likewise.

* configure.ac: Declare <bug-cuirass@framalistes.org> as package mailing list,
and <https://notabug.org/mthl/cuirass/> as package website.
* src/cuirass/ui.scm (show-package-information): Display them.

* Makefile.am (guilesitedir, pkgmoduledir, BUILT_SOURCES): Add whitespaces
around '='.

When building Cuirass with 'guix build -f build-aux/guix.scm' we don't want to
add "build-aux/guix.scm" in the repository snapshot since it is considered as
metadata.  As a consequence we can't make 'autoconf' require it.

* configure.ac (AC_REQUIRE_AUX_FILE): Remove "build-aux/guix.scm".
* Makefile.am (EXTRA_DIST): Only distribute it.

* Makefile.am <Generated files>: Fix typo "the" => "they".

* Makefile.am (nodist_guilesite_DATA, nodist_pkgmodule_DATA, CLEANFILES): Use
portable substitution references.

* guix.scm: Delete.
* build-aux/guix-env: Likewise.
* build-aux/guix.scm: New file.
* configure.ac (AC_REQUIRE_AUX_FILE): Distribute it.
* README <Build Instructions>: Document it.

* guix/ci.scm: Delete file.  Guix already provides a package definition for
Cuirass.
* build-aux/pre-inst-env.in (GUIX_PACKAGE_PATH): Remove.

* build-aux/git-version-gen: New script.
* configure.ac (AC_INIT): Use it.
(AC_REQUIRE_AUX_FILE): Distribute it.
* Makefile.am (.version): New target.
(BUILT_SOURCES, EXTRA_DIST): Add it.
(dist-hook): Generate ".tarball-version".
* .gitignore: Update.

* bin/cuirass.in (%options): Add "--port" and "-p" command line options.
(show-help): Adapt.
(main): Set default to 8080.  Call 'run-cuirass-server' with this.
* src/cuirass/http.scm (run-cuirass-server): Display the port number.
* doc/cuirass.texi (Invocation): Document new option.

* src/cuirass/http.scm (run-cuirass-server): Add 'port' keyword argument.

* src/cuirass/config.scm.in (%datadir, %localstatedir): Don't refer to
previous '$prefix' expansion hack in comments.

This reverts most of 4f0d6657.  The load paths
are still hard coded after installation, however 'pre-inst-env' wrapper is
used for defining them in the local build environment.  This is more
convenient for running the tests manually or launching a Guile REPL with all
the Cuirass modules accessible.

* build-aux/pre-inst-env.in (GUILE_LOAD_PATH, GUILE_LOAD_COMPILED_PATH): New
variables.
* bin/cuirass.in: Comment Guile load paths.
* Makefile.am (local_load_path, local_load_compiled_path): Delete.
(AM_TESTS_ENVIRONMENT): Don't set Guile load paths.
(do_subst): Use install directories for Guile load paths.
(install-exec-hook): Uncomment 'cuirass' hard coded load paths.

the 'Introduction' chapter.
