Add KUnit tests to the klist linked-list structure.
These perform testing for different variations of node add
and node delete in the klist data structure (<linux/klist.h>).
Limitation: Since we use a static global variable, and if
multiple instances of this test are run concurrently, the test may fail.

The s390 specific test_unwind kunit test has 39 parameterized tests. The
results in debugfs are truncated since the full log doesn't fit into 1500
bytes.
Therefore increase KUNIT_LOG_SIZE to 2048 bytes in a similar way like it
was done recently with commit "kunit: fix bug in debugfs logs of
parameterized tests". With that the whole test result is present.

Copy/pasting the code from the kernel-doc here doesn't compile because
kunit_alloc_resource() takes a gfp flags argument. Pass the gfp
argument from the caller to complete the example.

Basically, get this command to be happy and make run_checks.py happy
$ mypy --strict --exclude '_test.py$' --exclude qemu_configs/ ./tools/testing/kunit/
Primarily the changes are
* add `-> None` return type annotations
* add all the missing argument type annotations
Previously, we had false positives from mypy in `main()`, see commit
09641f7c7d8f ("kunit: tool: surface and address more typing issues").
But after commit 2dc9d6ca52a4 ("kunit: kunit.py extract handlers")
refactored things, the variable name reuse mypy hated is gone.
Note: mypy complains we don't annotate the types the unused args in our
signal handler. That's silly.
But to make it happy, I've copy-pasted an appropriate annotation from
https://github.com/python/typing/discussions/1042#discussioncomment-2013595.

We don't run a linter regularly over kunit.py code (the default settings
on most don't like kernel style, e.g. tabs) so some of these imports
didn't get removed when they stopped being used.

E.g. for subprocess.Popen, it can be opened in `text=True` mode where it
returns strings, or `text=False` where it returns bytes.
To differentiate, you can annotate types as `Popen[str]` or
`Popen[bytes]`.
This patch should add subscripts in all the places we were missing them.

Fix bug of the extra newline characters in debugfs logs. When a
line is added to debugfs with a newline character at the end,
an extra line appears in the debugfs log.
This is due to a discrepancy between how the lines are printed and how they
are added to the logs. Remove this discrepancy by checking if a newline
character is present before adding a newline character. This should closely
match the printk behavior.
Add kunit_log_newline_test to provide test coverage for this issue. (Also,
move kunit_log_test above suite definition to remove the unnecessary
declaration prior to the suite definition)
As an example, say we add these two lines to the log:
kunit_log(..., "KTAP version 1\n");
kunit_log(..., "1..1");
The debugfs log before this fix:
KTAP version 1
1..1
The debugfs log after this fix:
KTAP version 1
1..1

Fix bug in debugfs logs that causes an incorrect order of lines in the
debugfs log.
Currently, the test counts lines that show the number of tests passed,
failed, and skipped, as well as any suite diagnostic lines,
appear prior to the individual results, which is a bug.
Ensure the order of printing for the debugfs log is correct. Additionally,
add a KTAP header to so the debugfs logs can be valid KTAP.
This is an example of a log prior to these fixes:
KTAP version 1
# Subtest: kunit_status
1..2
# kunit_status: pass:2 fail:0 skip:0 total:2
# Totals: pass:2 fail:0 skip:0 total:2
ok 1 kunit_status_set_failure_test
ok 2 kunit_status_mark_skipped_test
ok 1 kunit_status
Note the two lines with stats are out of order. This is the same debugfs
log after the fixes (in combination with the third patch to remove the
extra line):
KTAP version 1
1..1
KTAP version 1
# Subtest: kunit_status
1..2
ok 1 kunit_status_set_failure_test
ok 2 kunit_status_mark_skipped_test
# kunit_status: pass:2 fail:0 skip:0 total:2
# Totals: pass:2 fail:0 skip:0 total:2
ok 1 kunit_status

Fix bug in debugfs logs that causes individual parameterized results to not
appear because the log is reinitialized (cleared) when each parameter is
run.
Ensure these results appear in the debugfs logs, increase log size to
allow for the size of parameterized results. As a result, append lines to
the log directly rather than using an intermediate variable that can cause
stack size warnings due to the increased log size.
Here is the debugfs log of ext4_inode_test which uses parameterized tests
before the fix:
KTAP version 1
# Subtest: ext4_inode_test
1..1
# Totals: pass:16 fail:0 skip:0 total:16
ok 1 ext4_inode_test
As you can see, this log does not include any of the individual
parametrized results.
After (in combination with the next two fixes to remove extra empty line
and ensure KTAP valid format):
KTAP version 1
1..1
KTAP version 1
# Subtest: ext4_inode_test
1..1
KTAP version 1
# Subtest: inode_test_xtimestamp_decoding
ok 1 1901-12-13 Lower bound of 32bit < 0 timestamp, no extra bits
... (the rest of the individual parameterized tests)
ok 16 2446-05-10 Upper bound of 32bit >=0 timestamp. All extra
# inode_test_xtimestamp_decoding: pass:16 fail:0 skip:0 total:16
ok 1 inode_test_xtimestamp_decoding
# Totals: pass:16 fail:0 skip:0 total:16
ok 1 ext4_inode_test
