When compiling the selftests with the -std=gnu99 option the build can
fail with.
Following build error:
test_core.c: In function ‘test_cgcore_destroy’:
test_core.c:87:2: error: ‘for’ loop initial declarations are only
allowed in C99 mode
for (int i = 0; i < 10; i++) {
^
test_core.c:87:2: note: use option -std=c99 or -std=gnu99 to compile
Add -std=gnu99 to the clone3 selftest Makefile to fix this.

As the UAPI headers start to appear in distros, we need to avoid
outdated versions of struct clone_args to be able to test modern
features, named "struct __clone_args". Additionally update the struct
size macro names to match UAPI names.

This Kselftest update for Linux 5.9-rc1 consists of
- TAP output reporting related fixes from Paolo Bonzini and Kees Cook.
These fixes make it skip reporting consistent with TAP format.
- Cleanup fixes to framework run_tests from Yauheni Kaliuta

Here are 3 SPDX patches for 5.7-rc1.
One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.
Nothing too complex, but you will get a merge conflict with your current
tree, that should be trivial to handle (one file modified by two things,
one file deleted.)
All 3 of these have been in linux-next for a while, with no reported
issues other than the merge conflict.

Expand the cgroup test-suite to include tests for CLONE_INTO_CGROUP.
This adds the following tests:
- CLONE_INTO_CGROUP manages to clone a process directly into a correctly
delegated cgroup
- CLONE_INTO_CGROUP fails to clone a process into a cgroup that has been
removed after we've opened an fd to it
- CLONE_INTO_CGROUP fails to clone a process into an invalid domain
cgroup
- CLONE_INTO_CGROUP adheres to the no internal process constraint
- CLONE_INTO_CGROUP works with the freezer feature

This tests clone3() with *set_tid to see if all desired PIDs are working
as expected. The tests are trying multiple invalid input parameters as
well as creating processes while specifying a certain PID in multiple
PID namespaces at the same time.
Additionally this moves common clone3() test code into clone3_selftests.h.

This adds tests for clone3() with different values and sizes
of struct clone_args.
This selftest was initially part of of the clone3() with PID selftest.
After that patch was almost merged Eugene sent out a couple of patches
to fix problems with these test.
This commit now only contains the clone3() selftest after the LPC
decision to rework clone3() with PID to allow setting the PID in
multiple PID namespaces including all of Eugene's patches.
