graph: Allow store file names for 'derivation' and 'references' graphs.
* guix/scripts/graph.scm (%derivation-node-type)[convert]: Add 'derivation-path?' and catch-all clauses. (%reference-node-type)[convert]: Add 'store-path?' and catch-all clauses. (assert-package, nodes-from-package): New procedures. (%package-node-type, %bag-node-type,%bag-with-origins-node-type) (%bag-emerged-node-type): Add 'convert' field (guix-graph): Rename 'packages' to 'items' and allow 'store-path?' arguments. * guix/graph.scm (<node-type>)[convert]: Adjust comment. * doc/guix.texi (Invoking guix graph): Document it.
