tests: Make ‘guix time-machine’ test effective.
The test as added in 79ec651a28 had no
effect: first because ‘guix time-machine --commit=X’, not followed by a
command, does nothing, and second because the “! COMMAND” shell stanza
does not have the desired effect (see <https://issues.guix.gnu.org/62406>).

This change rewrites the test to make it effective.

* tests/guix-time-machine.sh: Rewrite.

grafts: Fix corner case involving multiple-output derivations.
Fixes a bug that would occur with references to two outputs of the same
derivation, with one of them referring to the other one.

For example, the references of libreoffice include both mariadb:dev and
mariadb:lib; additionally, mariadb:dev refers to mariadb:lib.  In this
case, the glibc graft would not be applied on one of the mariadb paths,
and both the grafted and ungrafted glibc would end up in the closure of
libreoffice.

Fixes <https://issues.guix.gnu.org/66662>.

to outputs of DRV other than OUTPUTS.

gnu: services: Revert to deleting and updating all matching services
This patch reverts the behavior introduced in
1819512073 which caused ‘modify-services’
clauses to only match a single instance of a service.

We will now match all service instances when doing a deletion or update, while
still raising an exception when trying to match against a service that does
not exist in the services list, or which was deleted explicitly by a ‘delete’
clause (or an update clause that returns ‘#f’ for the service).

Fixes: #64106

packages: 'package-transitive-supported-systems' detects cycles.
With this change, commands such as 'guix build' or 'guix package' report
obvious package-level cycles upfront.  Derivation-level cycles are not
detected.

type.
(package-transitive-supported-systems): Define 'visited', check it, and
parameterize it.
* guix/ui.scm (call-with-error-handling): Handle
'&package-cyclic-dependency-error'.

cycles"): Add test.

tests: Ensure 'elpa' test does not access the network.
Previously it would try to access the real elpa.gnu.org.  This would
succeed when network is available because "taxy-magit-section" is an
existing package.

* guix/import/elpa.scm (elpa-repository)
(package-from-elpa-repository?): Recognize 'gnu/http.
* tests/elpa.scm ("package-latest-release"): Use 'http' instead of
'https'.  Change "taxy-magit-section" to "fake-taxy-magit-section".
