This reverts commit 5f93d97005.
'guix pull' would fail because (guix self) needs 'scheme-files'
from (guix discovery), which was not exported until now.
This mitigates <https://bugs.gnu.org/27284>.
* guix/self.scm: New file.
* Makefile.am (MODULES): Add it.
* build-aux/build-self.scm (libgcrypt, zlib, gzip, bzip2, xz)
(false-if-wrong-guile, package-for-current-guile, guile-json)
(guile-ssh, guile-git, guile-bytestructures): Remove.
(build): Rewrite to simply delegate to 'compiled-guix'.
* gnu/packages.scm (%distro-root-directory): Rewrite to try different
directories.
* guix/discovery.scm (guix): Export 'scheme-files'.
* guix/scripts/pull.scm (build-and-install): Split into...
(install-latest): ... this. New procedure. And...
(build-and-install): ... this, which now takes a monadic value argument.
(indirect-root-added): Remove.
(guix-pull): Call 'add-indirect-root'. Call 'build-from-source' and
pass the result to 'build-and-install'.
* build-aux/hydra/gnu-system.scm (package->job): Create a 'base.' job
when PACKAGE is a member of BASE-PACKAGES.
(all-packages)[adjust]: New procedure.
Fold over %FINAL-INPUTS and add it to the result.
Fixes <https://bugs.gnu.org/28956>.

* build-aux/build-self.scm (build): Add (guix build compile) to
#:modules.
* guix/build/pull.scm (build-guix): Wrap 'compile-files' call in
'with-directory-excursion'. Strip "./" from FILES when passing it to
'compile-files'.
This prevents libstore/build.cc from executing nix/scripts/offload, which is
always created by config.status, when offload support is not enabled.
* build-aux/pre-inst-env.in: Export 'NIX_BUILD_HOOK' only when
configured; unset it otherwise.
* guix/scripts/pull.scm (%snapshot-url, with-environment-variable)
(with-PATH): Remove.
(ensure-guile-git!): New procedure.
(%repository-url): New variable.
(%default-options): Add 'repository-url' and 'ref'.
(show-help, %options): Add '--commit' and '--url'.
(temporary-directory, first-directory, interned-then-deleted)
(unpack): Remove.
(build-from-source): Rename 'tarball' to 'source'. Remove call to
'unpack'.
(build-and-install): Rename 'tarball' to 'source'.
(honor-lets-encrypt-certificates!, report-git-error): New procedures.
(with-git-error-handling): New macro.
(guix-pull)[fetch-tarball]: Remove.
Wrap body in 'with-git-error-handling'. Rewrite to use
'latest-repository-commit'.
* build-aux/build-self.scm (build): Print an error message and exit when
GUILE-GIT is #f.
* doc/guix.texi (Invoking guix pull): Mention Git. Document '--commit'
and '--branch'.
* build-aux/hydra/gnu-system.scm (qemu-jobs): Add 'iso9660-image .
* gnu/build/vm.scm (make-iso9660-image): New variable. Export it.
* gnu/system/vm.scm (iso9660-image): New variable. Use make-iso9660-image.
(system-disk-image): Use iso9660-image.
* build-aux/build-self.scm (guile-git, guile-bytestructures): New
variables.
(build): Add guile-git and guile-bytestructures to %load-path and
%load-compiled-path.
* build-aux/update-NEWS.scm: New file.
* Makefile.am (EXTRA_DIST): Add it.
(GUIX_MAINTENANCE_DIRECTORY): New variable.
(update-NEWS): New target.
(.PHONY): Add it.
Previously, 'guix pull' would always build with Guile 2.0.
Now it builds with the Guile that matches (effective-version).
* build-aux/build-self.scm (false-if-wrong-guile)
(package-for-current-guile): New procedures.
(guile-json, guile-ssh): Use it.
(guile-for-build): New procedure.
(build): Use (effective-version) instead of the hard-coded "/2.0".
Add (guix modules) closure to #:modules argument. Pass
\#:guile-for-build argument to 'gexp->derivation'.
* guix/build/pull.scm (depends-on-guile-ssh?, all-scheme-files): New
procedures.
(build-guix): Show the output of (version). Use the above procedures.
Filter out files that match 'depends-on-guile-ssh?' when (ssh session)
is missing.
* build-aux/update-guix-package.scm: New file.
* Makefile.am (EXTRA_DIST): Add it.
(update-guix-package): New target.
(.PHONY): Add it.
* gnu/packages/package-management.scm (guix): Mention it.
* Makefile.am (EXTRA_DIST, BUILT_SOURCES): Add $(top_srcdir)/.version.
($(top_srcdir)/.version, gen-tarball-version): New targets.
(dist-hook): Depend on 'gen-tarball-version'.
(.PHONY): Add 'gen-tarball-version'.
* build-aux/git-version-gen: New file, from Gnulib v0.1-1312-ga87d5e5c6.
* configure.ac: Use it in 'AC_INIT'. Use 'https' for the URL.
Previously it would print them with 'display', which was inconvenient.
* build-aux/test-driver.scm (test-display): Use ~S for VALUE.
(test-runner-gnu): Use 'format' instead of 'test-display' for the test
name, location, and result kind.
* build-aux/compile-all.scm (%default-optimizations)
(%lightweight-optimizations): New variables.
(optimization-options): New procedure.
(compile-file*): Use it.
Fixes <http://bugs.gnu.org/26022>.
Reported by Efraim Flashner <efraim@flashner.co.il>.
* build-aux/hydra/gnu-system.scm (hydra-jobs)[cross-jobs](from-32-to-64?):
Check whether TARGET contains "64" rather than checking whether TARGET
ends in "64", which is rarely the case.
(same?): Add special case for armhf-linux.
