The commit [1] added a sed command used to retreive a pattern
to keep only defconfigs whose name start with the pattern.
"<foo>-defconfigs-<pattern>"
The sed command doesn't work as expected if <foo> contains a
single hyphen [2]:
"qemu-6.2.0-defconfigs-qemu"
Update the sed command to ignore completely the part before
"-defconfigs-".

Already supported:
- Pushing a branch called "<foo>-defconfigs" tests all defconfigs.
- Pushing a branch called "<foo>-defconfig-<defconfig-name>" will
test one particular defconfig
This commit adds support for:
- Pushing a branch called "<foo>-defconfigs-<pattern>" which will
test all defconfigs whose name start with the pattern. For example
"<foo>-defconfigs-qemu_" will test all Qemu defconfigs

Currently when a tag is added to the Buildroot git tree, the gitlab-ci
create a pipeline with several hundred of jobs (~750) to build all
defconfigs and execute the Buildroot testsuite.
However, there is only a limited number of gitlab-ci runner (9 runners)
and some jobs reach the timeout limit (24h) while waiting for a runner
[1]. Indeed, the Buildroot project doesn't use the Gitlab's shared
runners.
In addition to the pipeline created when a new tag is added to the
git repository, two pipelines are created each weeks to execute the
Buildroot testsuite (on monday [2]) and build all defconfigs (on
Thursday [3]).
At some point there are too many jobs waiting in gitlab due board
defconfigs builds. Indded a board defconfig requires a lot of time
(~30min) compared to other jobs in order to build a toolchain and a
kernel linux along with a basic rootfs. There is currently 262
defconfigs.
This is even worse when several pipelines are trigged at the same
time (new git tag and scheduled pipeline trigger).
In order to reduce the number of long jobs, don't build board
defconfigs with pipelines trigged on tag, keeping only the runtime
tests and the Qemu's defconfigs.

The current Gitlab CI mechanism allows to trigger all tests in a CI
pipeline by pushing a branch named <something>-runtime-tests, or to
trigger a single test in a CI pipeline by pushing a branch name
<something>-tests.<name of test>.
However, there are cases where it is useful to run a suite of tests,
for example to run all tests in tests.init.test_busybox.
This commit makes that possible by extending the current semantic of
<something>-tests.<name of test> to not expect a complete test name,
but instead to accept all tests that starts with the given pattern.
This allows to do:
git push gitlab HEAD:foobar-tests.init.test_busybox.TestInitSystemBusyboxRo
like it was the case before. But it now also allows to do:
git push gitlab HEAD:foobar-tests.init.test_busybox
to run all Busybox tests.

The gitlab-ci support in test-pkg allows to parallelize the test-pkg
work into several gitlab jobs. It's much faster than local serialized
testing.
To trigger this, a developer will have to add, in the latest commit of
their branch, a token on its own line, followed by a configuration
fragment, e.g.:
test-pkg config:
SOME_OPTION=y
# OTHER_OPTION is not set
SOME_VARIABLE="some value"
This configuration fragment is used as input to test-pkg.
To be able to generate one job per test to run, we need the list of
tests in the parent pipeline, and the individual .config files (one per
test) in the child pipeline. We use the newly-introduced --prepare-only
mode to test-pkg, and collect all the generated .config files as
artefacts; those are inherited in the child pipeline via the
"needs::pipeline" and "needs::job" directives. This is a bit tricky,
and is best described by the Gitlab-CI documentation [0].
We also list those .config files to generate the actual list of jobs to
run in the child pipeline.
Notes:
- if the user provides an empty fragment, this is considered an error:
indeed, without a fragment (and the package name), there is no way
to know what to test;
- if that fragment yields an empty list of tests, then there is
nothing to test either, so that is also considered an error.

Currently, we handle three kinds of tests: basic, defconfig, and
runtime, and we treat them totally independently ones from the others.
Except for the basic tests that are ignored when defconfig or runtime
tests are explicitly requested.
The basic tests are also run systematically on all our reference
branches: master, next (when it exists), and the maintenance branches:
YYYY.MM.x.
Furthermore, we can see that the conditions to run each set of tests
are very similar, with only the explicit queries differing by name.
Rework the script so that the conditions are expressed only once, and
each set of tests is decided for each condition. This makes it easier
to decide what tests should run under what conditions.
Using GitLab-CI's schedules, with a variable expressing the actual test
to run, would seem the obvious choice to trigger the pipelines. However,
a schedule is configured for a specific branch, which means we would
need one schedule per branch we want to build per test cases we want to
run, *and* that we update those schedules when we add/remove branches
(e.g. when we open/close 'next', or a maintenance branch). This is not
very nice, as it requires some manual tweaking and twiddling on the web
UI.
Instead, we resort to using triggers, that will be triggered from a
cronjob on some server. Using a cronjiob allows us to more easily manage
the branches we want to test and test cases we want to run, to more
easily spread the load over the week, etc...
Note: triggering a pipeline can be done with a simple curl invocation:
$ curl -X POST \
-F "token=${YOUR_TOKEN}" \
-F "ref=${BRANCH_TO_TEST}" \
-F "variables[BR_SCHEDULE_JOBS]=${TEST_TO_RUN}" \
"https://gitlab.com/api/v4/projects/${YOUR_PROJECT_ID}/trigger/pipeline"

When multiple conditions match simultaneously, even though that should
not happen in practice, we want the more "important" one to win over
the less "important" ones. For example, a tag is more important than a
branch name or a trigger.
Currently, the latest condition to match takes precendence over any
previous one, while we want the exact opposite.
Fix that with proper fallbacks in else-blocks.

Currently, the check of defconfigs is run for all branches, even those
that are pushed only to run runtime tests. This is very inconvenient.
In fact, we only want to check the defconfigs on standard branches, that
is master, next, and the maintenance branches.
This will also decrease drastically the number gitlab-ci minutes used
when one pushes their repo to gitlab.com, where the number of CI minutes
are now going to be pretty severely restricted.

Note that those tests were so far ignored only when requesting a single
defconfig build, or a single runtime test build; everything else
was trigerring thoses tests.
However, it feels more natural that they are also ignored when all
defconfigs build. or all runtime tests, are explictly requested.

The defconfig check has been introduced by the previous
patch before the building each defconfig but those builds
are done every week or more.
Checking if a defconfig is valid can be done on every
push in the repository since it take few seconds.
This would allow to detect as soon as possible a problem
in a defconfig and eventually avoid breaking the build
while build testing all defconfig.
Introduce a new job template ".defconfig_check" in
gitlab-ci.yml.in and modify the generate-gitlab-ci-yml
to create a job for each defconfig to run the test.
Although, we could have used only one job to do all
tests, using one job per defconfig allow to identify
easily in gitlab which defconfig is falling.

Replace all YAML anchors with the new "extends" keyword because it is
more readable and more flexible (it works across configuration files
combined with the new "include" keyword).
Readability is more meaningful in .gitlab-ci.yml.in.
In the part of .gitlab-ci.yml that is auto-generated by 'make
.gitlab-ci.yml' keep the keyword in the same line of the job name.
So instead of this:
zynqmp_zcu106_defconfig:
extends: .defconfig
tests.boot.test_atf.TestATFAllwinner:
extends: .runtime_test
Use this:
zynqmp_zcu106_defconfig: { extends: .defconfig }
tests.boot.test_atf.TestATFAllwinner: { extends: .runtime_test }
Do this to to keep .gitlab-ci.yml easier to be post-processed by a
script.

GitLab has severe limitations imposed to triggers.
Using a variable in a regexp is not allowed:
| only:
| - /-$CI_JOB_NAME$/
| - /-\$CI_JOB_NAME$/
| - /-%CI_JOB_NAME%$/
Using the key 'variables' always lead to an AND with 'refs', so:
| only:
| refs:
| - branches
| - tags
| variables:
| - $CI_JOB_NAME == $CI_COMMIT_REF_NAME
would make the push of a tag not to trigger all jobs anymore.
Inheritance is used only for the second level of keys, so:
|.runtime_test: &runtime_test
| only:
| - tags
|tests.package.test_python_txaio.TestPythonPy2Txaio:
| <<: *runtime_test
| only:
| - /-TestPythonPy2Txaio$/
would override the entire key 'only', making the push of a tag not to
trigger all jobs anymore.
So, in order to have a trigger per job and still allow the push of a tag
to trigger all jobs (all this in a follow up patch), the regexp for each
job must be hardcoded in the .gitlab-ci.yml and also the inherited
values for key 'only' must be repeated for every job.
This is not a big issue, .gitlab-ci.yml is already automatically
generated from a template and there will be no need to hand-editing it
when jobs are added or removed.
Since the logic to generate the yaml file from the template will become
more complex, move the commands from the main Makefile to a script.
Using Python or other advanced scripting language for that script would
be the most versatile solution, but that would bring another dependency
on the host machine, pyyaml if Python is used. So every developer that
needs to run 'make .gitlab-ci.yml' and also the docker image used in the
GitLab pipelines would need to have pyyaml pre-installed.
Instead of adding the mentioned dependency, keep using a bash script.
While moving the commands to the script:
- mimic the behavior of the previous make target and fail on any
command that fails, by using 'set -e';
- break the original lines in one command per line, making the diff for
any patch to be applied to this file to look nicer;
- keep the script as simple as possible, without functions, just a
script that executes from the top to bottom;
- do not perform validations on the input parameters, any command that
fails already makes the script to fail;
- do not add an usage message, the script is not intended to be called
directly.
This patch does not change functionality.
