* guix/graph.scm (<graph-backend>): Add fields "name" and "description".
(%graphviz-backend): Provide values for name and description.
(export-graph): Ignore name and description when matching backends.
(graph-backend-name, graph-backend-description): New procedures.
* tests/graph.scm (make-recording-backend): Initialize name and
description fields of test graph-backend.
* guix/scripts/graph.scm (ensure-store-items): New procedure.
(%reference-node-type)[convert]: Use it.
(non-derivation-referrers): New procedure.
(%referrer-node-type): New variable.
(%node-types): Add it.
* tests/graph.scm ("referrer DAG"): New test.
* doc/guix.texi (Invoking guix graph): Document it.
Before that '.log' files for scheme tests were fragmented and not
included in test-suite.log. This unifies the semantics of SRFI-64 API
with Automake test suite.
* build-aux/test-driver.scm: New file.
* Makefile.am (SCM_LOG_DRIVER, AM_SCM_LOG_DRIVER_FLAGS): New variables.
(SCM_LOG_COMPILER, AM_SCM_LOG_FLAGS): Delete variables.
(AM_TESTS_ENVIRONMENT): Set GUILE_AUTO_COMPILE to 0.
* test-env.in: Silence guix-daemon.
* doc/guix.texi (Running the Test Suite): Describe how to display the
detailed results. Bug reports require only 'test-suite.log' file.

tests/utils.scm: Don't exit at the end of test groups.
* tests/containers.scm: Likewise. Use 'test-skip' instead of exiting
with error code 77.
This allows tests to run as expected even in the presence of
replacements among the bootstrap packages, such as Perl (commit
d8173f21f7).
* tests/cpan.scm: Add (%graft? #f).
* tests/derivations.scm: Likewise.
* tests/graph.scm: Likewise.
* tests/monads.scm: Likewise.
* tests/profiles.scm: Likewise.
* tests/gexp.scm: Likewise.
("gexp->derivation vs. grafts"): Explicitly reenable grafting before,
and disable it after, using 'set-grafting'.
Before that it would include #f for most origins since that the default
value of 'origin-patch-guile'.
* guix/scripts/graph.scm (bag-node-edges): When 'origin-patch-guile'
returns #f, use (default-guile).
* tests/graph.scm ("bag DAG, including origins"): Check for an edge from
O to (default-guile).
Fixes <http://bugs.gnu.org/22280>.

* guix/scripts/graph.scm (%bag-emerged-node-type)[edges]: Mimic
%BAG-NODE-TYPE. This is a followup to 38b92da.
