* guix/channels.scm (latest-channel-instance): Add #:starting-commit and
pass it to 'update-cached-checkout'. Return the commit relation as a
second value.
(ensure-forward-channel-update): New procedure.
(latest-channel-instances): Add #:current-channels and #:validate-pull.
[current-commit]: New procedure.
Pass #:starting-commit to 'latest-channel-instance'. When the returned
relation is true, call VALIDATE-PULL.
(latest-channel-derivation): Add #:current-channels and #:validate-pull.
Pass them to 'latest-channel-instances*'.
* tests/channels.scm ("latest-channel-instances #:validate-pull"): New
test.
