store-copy: 'read-reference-graph' returns a list of records.
The previous implementation of 'read-reference-graph' was good enough for many use cases, but it discarded the graph structure, which is useful information in some cases. * guix/build/store-copy.scm (<store-info>): New record type. (read-reference-graph): Rewrite to return a list of <store-info>. (closure-size, populate-store): Adjust accordingly. * gnu/services/base.scm (references-file): Adjust accordingly. * gnu/system/vm.scm (system-docker-image): Likewise. * guix/scripts/pack.scm (squashfs-image, docker-image): Likewise. * tests/gexp.scm ("gexp->derivation #:references-graphs"): Likewise.
