* tests/packages.scm ("fold-available-packages with/without cache"):
Remove 'find-duplicates'.  Add 'list->set*' and use it instead of
'find-duplicates', 'delete-duplicates', and 'lset='.

This allows users to use '--with-debug-info=rdma-core' and is otherwise
equivalent to "Release".

* gnu/packages/linux.scm (rdma-core)[arguments]: Remove #:build-type.

Fixes <https://bugs.gnu.org/46229>.

This flag was added in commit 2b14c60d.
It is apparently no longer needed.  Worse, it now causes segfaults when
used with Omni-Path devices, as reported in the bug above.

* gnu/packages/linux.scm (rdma-core)[arguments]: Remove
"-DIOCTL_MODE=write" from #:configure-flags.

* gnu/packages/ci.scm (cuirass): Update to 0.0.1-63.da93cb9.

This reverts commit ba3e25bb.

This commit is reverted because it caused kwayland to no longer build on the
build farm. Specifically, the test "PlasmaWindowModelTest::testVirtualDesktops"
fails.

* build-aux/test-driver.scm: Add an exec-based shebang and set the script
executable bit.
(main): Insert a newline after the version string is printed with --version.

* build-aux/test-driver.scm (show-help): Add the help text for the
new '--errors-only' option.
(%options): Add the errors-only option.
(test-runner-gnu): Add the errors-only? parameter and update doc.  Move the
logging of the test data after the test has completed, so a choice can be made
whether to keep it or discard it based on the value of the test result.
(main): Pass the errors-only? option to the driver.
* doc/guix.texi (Running the Test Suite): Document the new option.

* build-aux/test-driver.scm (show-help): Add help text for the new --select
and --exclude options.
(%options): Add the new select and exclude options.
(test-runner-gnu): Pass them to the test runner.  Update doc.
(test-match-name*, test-match-name*/negated, %test-match-all): New variables.
(main): Compute the test specifier based on the values of the new options and
apply it to the current test runner when running the test file.
* doc/guix.texi (Running the Test Suite): Document the new options.

The Automake parallel test harness does its own smart detection of the
terminal color capability and always provides the --color-tests argument to
the driver.  This change defaults the --color-tests argument to true when the
test driver is run on its own (not via Automake).

* build-aux/test-driver.scm (main): Set the default value of the --color-tests
argument to true when it's not explicitly provided.

This makes it easier (and less surprising) for users to experiment with the
custom Scheme test driver directly.  The behavior is unchanged from Automake's
point of view.

* build-aux/test-driver.scm (main): Make the --log-file and --trs-file
arguments optional and update doc.  Only open, redirect and close a port to a log file when
the --log-file option is provided.  Only open and close a port to a trs file
when the --trs-file option is provided.
(test-runner-gnu): Set OUT-PORT parameter default value to the current output
port.  Set the TRS-PORT parameter default value to a void port.  Update doc.

* gnu/packages/backup.scm (dump): Update to 0.4b47.
[inputs]: Replace OPENSSL-1.0 with OPENSSL.
