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/base32.scm, tests/build-utils.scm, tests/builders.scm,
tests/challenge.scm, tests/cpan.scm, tests/cpio.scm, tests/cran.scm,
tests/cve.scm, tests/derivations.scm, tests/elpa.scm,

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.
* guix/scripts/substitute.scm (lookup-narinfos/diverse): New procedure.
(lookup-narinfo): Use it.
(process-query): Change #:cache-url to #:cache-urls.
[valid?]: Remove 'narinfo?' check, which is no longer necessary.
Use 'lookup-narinfos/diverse' instead of 'lookup-narinfos'.
(process-substitution): Change #:cache-url to #:cache-urls.
(%cache-url): Rename to...
(%cache-urls): ... this. Turn into a list.
(guix-substitute): Remove 'getaddrinfo' test with early exit. Adjust
calls to 'process-query' and 'process-substitution'.
* tests/substitute.scm: Change '%cache-url' to '%cache-urls'.
