Works around <https://bugs.gnu.org/28211>.
Reported by Marius Bakke <mbakke@fastmail.com>.
* guix/packages.scm (guile-2.0): New procedure.
(package-derivation, package-cross-derivation): Use it when computing
the #:guile argument to 'graft-derivation'.
This provides a ~2x speedup when using 4 threads.
* guix/packages.scm (patch-and-repack)[build]: Invoke xz with
'--threads=0' when re-packing tarballs.
* guix/packages.scm (package-mapping): New procedure.
(package-input-rewriting): Rewrite in terms of 'package-mapping'.
* tests/packages.scm ("package-mapping"): New test.
* doc/guix.texi (Defining Packages): Document it.

at <https://lists.gnu.org/archive/html/help-guix/2017-04/msg00007.html>.
* guix/packages.scm (expand-input): Add 'guard' form around call to
'package-source-derivation'.
* tests/packages.scm (dummy): New test.
* guix/packages.scm (package-upstream-name): New procedure.
* guix/gnu-maintenance.scm (gnu-package?, ftp-server/directory)
(latest-release*, latest-gnome-release)
(latest-kde-release): Use it instead of the inline expression.
This provides a way to mark a package as superseded by another one.
Upgrades replace superseded packages with their replacement.
* guix/packages.scm (package-superseded, deprecated-package): New
procedures.
* gnu/packages.scm (%find-package): Check for 'package-superseded'.
* guix/scripts/package.scm (transaction-upgrade-entry)[supersede]: New
procedure. Call it when 'package-superseded' is true.
* tests/guix-build.sh: Add test for a superseded package.
* tests/packages.scm ("package-superseded")
("transaction-upgrade-entry, superseded package"): New tests.

* guix/packages.scm (patch-and-repack)[build]: Use
'--no-backup-if-mismatch' patch flag to avoid making *.orig files.
The two mistakes made here (confusion between 'modules' and
'imported-modules') were canceling each other.
* guix/packages.scm (patch-and-repack): Use IMPORTED-MODULES, not
MODULES, as the base of the module list passed as #:modules to
'gexp->derivation'.
(origin->derivation): Pass IMPORTED-MODULES, not MODULES, as
the #:imported-modules argument of 'patch-and-repack'.
* gnu/packages/engineering.scm (fastcap)[source]: Add 'imported-modules'
field.
* guix/packages.scm (origin->derivation): Rename 'source' parameter to
'origin'. Move cases where SOURCE is a string to...
(package-source-derivation): ... here.
This reduces the wall-clock time of
guix environment gnutls --pure -E true
by ~35%.
* guix/packages.scm (%graft-cache): New variable.
(input-graft): Use 'cached' to cache to %GRAFT-CACHE.
This reduces the wall-clock time of
guix environment gnutls --pure -E true
by ~25%.
* guix/packages.scm (%bag-cache): New variable.
(package->bag): Use 'cached' to cache things to %BAG-CACHE.
* guix/packages.scm (cache): Rename to...
(cache!): ... this. Add 'cache' parameter, and use it.
(cached): Add a rule to allow the cache to be specified.
Fixes <http://bugs.gnu.org/22139>.
* guix/grafts.scm (graft-derivation): Rename to...
(graft-derivation/shallow): ... this.
(graft-origin-file-name, item->deriver, non-self-references)
(cumulative-grafts, graft-derivation): New procedures
* tests/grafts.scm ("graft-derivation, grafted item is a direct
dependency"): Clarify title. Use 'grafted' instead of 'graft' to refer
to the grafted derivation.
("graft-derivation, grafted item is an indirect dependency")
("graft-derivation, no dependencies on grafted output"): New tests.
* guix/packages.scm (input-graft): Change to take a package instead of
an input.
(input-cross-graft): Likewise.
(fold-bag-dependencies): New procedure.
(bag-grafts): Rewrite in terms of 'fold-bag-dependencies'.
* tests/packages.scm ("package-derivation, indirect grafts"): Comment out.
* doc/guix.texi (Security Updates): Mention run-time dependencies and
recursive grafting.
* guix/packages.scm <package>: Use '@' in record printer.
* guix/import/cabal.scm <cabal-package>: Likewise
* guix/import/elpa.scm <elpa-package>: Likewise.
* tests/packages.scm: Adapt to it.
* guix/packages.scm (package-transitive-native-search-paths): New
procedure.
* tests/packages.scm ("package-transitive-native-search-paths"): New
test.
This is a followup to commit 92226a470d.
* guix/packages.scm (patch-and-repack)[build]: Determine if tar supports the
"--sort=name" option using a run-time test. If not supported, generate the
sorted file list with 'find-files' and pass it to tar using "--files-from".
