commit c25ce589dc upstream.
Change every shebang which does not need an argument to use /usr/bin/env.
This is needed as not every distro has everything under /usr/bin,
sometimes not even bash.

[ Upstream commit 7421b1a4d1 ]
The first argument to namedtuple() should match the name of the type,
which wasn't the case for KconfigEntryBase.
Fixing this is enough to make mypy show no python typing errors again.

For simplcity, strip all trailing whitespace from parsed output.
I imagine no one is printing out meaningful trailing whitespace via
KUNIT_FAIL() or similar, and that if they are, they really shouldn't.
`isolate_kunit_output()` yielded liens with trailing \n, which results
in artifacty output like this:
$ ./tools/testing/kunit/kunit.py run
[16:16:46] [FAILED] example_simple_test
[16:16:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29
[16:16:46] Expected 1 + 1 == 3, but
[16:16:46] 1 + 1 == 2
[16:16:46] 3 == 3
[16:16:46] not ok 1 - example_simple_test
[16:16:46]
After this change:
[16:16:46] # example_simple_test: EXPECTATION FAILED at lib/kunit/kunit-example-test.c:29
[16:16:46] Expected 1 + 1 == 3, but

We should *not* be expecting lines to end with \n in kunit_tool_test.py
for this reason.
Do the same for `raw_output()` as well which suffers from the same
issue.
This is a followup to [1], but rebased onto kunit-fixes to pick up the
other raw_output() fix and fixes for kunit_tool_test.py.

Currently the tool redirects make stdout + stderr, and only shows them
if the make command fails.
This means build warnings aren't shown to the user.
This change prints the contents of stderr even if make succeeds, under
the assumption these are only build warnings or other messages the user
likely wants to see.
We drop stdout from the raised exception since we can no longer easily
collate stdout and stderr and just showing the stderr seems fine.
Example with a warning:
[14:56:35] Building KUnit Kernel ...
../lib/kunit/kunit-test.c: In function ‘kunit_test_successful_try’:
../lib/kunit/kunit-test.c:19:6: warning: unused variable ‘unused’ [-Wunused-variable]
19 | int unused;
| ^~~~~~
[14:56:40] Starting KUnit Kernel ...
Note the stderr has a trailing \n, and since we use print, we add
another, but it helps separate make and kunit.py output.
Example with a build error:
[15:02:45] Building KUnit Kernel ...
ERROR:root:../lib/kunit/kunit-test.c: In function ‘kunit_test_successful_try’:

The code uses annotations, but they aren't accurate.
Note that type checking in python is a separate process, running
`kunit.py run` will not check and complain about invalid types at
runtime.
Fix pre-existing issues found by running a type checker
$ mypy *.py
All but one of these were returning `None` without denoting this
properly (via `Optional[Type]`).

When JSON support was added in [1], the KunitParseRequest tuple was
updated to contain a 'build_dir' field, but kunit.py parse doesn't
accept --build_dir as an option. The code nevertheless tried to access
it, resulting in this error:
AttributeError: 'Namespace' object has no attribute 'build_dir'
Given that the parser only uses the build_dir variable to set the
'build_environment' json field, we set it to None (which gives the JSON
'null') for now. Ultimately, we probably do want to be able to set this,
but since it's new functionality which (for the parse subcommand) never
worked, this is the quickest way of getting it back up and running.

Due to the raw_output() function on kunit_parser.py actually being a
generator, it only runs if something reads the lines it returns. Since
we no-longer do that (parsing doesn't actually happen if raw_output is
enabled), it was not printing anything.

Pull more Kunit updates from Shuah Khan:
- add Kunit to kernel_init() and remove KUnit from init calls entirely.
This addresses the concern that Kunit would not work correctly during
late init phase.
- add a linker section where KUnit can put references to its test
suites.
This is the first step in transitioning to dispatching all KUnit
tests from a centralized executor rather than having each as its own
separate late_initcall.
- add a centralized executor to dispatch tests rather than relying on
late_initcall to schedule each test suite separately. Centralized
execution is for built-in tests only; modules will execute tests when
loaded.
- convert bitfield test to use KUnit framework
- Documentation updates for naming guidelines and how
kunit_test_suite() works.
- add test plan to KUnit TAP format

CalledProcessError stores the output of the failed process as `bytes`,
not a `str`.
So when we log it on build error, the make output is all crammed into
one line with "\n" instead of actually printing new lines.
After this change, we get readable output with new lines, e.g.
> CC lib/kunit/kunit-example-test.o
> In file included from ../lib/kunit/test.c:9:
> ../include/kunit/test.h:22:1: error: unknown type name ‘invalid_type_that_causes_compile’

Secondly, trying to concat exceptions to strings will fail with
> TypeError: can only concatenate str (not "OSError") to str
so fix this with an explicit cast to str.

Direct stderr to subprocess.STDOUT so error messages get included in the
subprocess.CalledProcessError exceptions output field. This results in
more meaningful error messages for the user.
This is already being done in the make_allyesconfig method. Do the same
for make_mrproper, make_olddefconfig, and make methods.
With this, failures on unclean trees [1] will give users an error
message that includes:
"The source tree is not clean, please run 'make ARCH=um mrproper'"
