44eebacd6b selftests: clone3: remove duplicate defines 
Remove duplicate defines which are already included in kernel headers.
MAX_PID_NS_LEVEL macro is used inside kernel only. It isn't exposed to
userspace. So it is never defined in test application. Remove #ifndef in
this case.

e953aeaa91 selftests/clone3: Avoid OS-defined clone_args 
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outdated versions of struct clone_args to be able to test modern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.

51ad5b54b6 selftests/clone3: Reorder reporting output 
Selftest output reporting was happening before the TAP headers and plan
had been emitted. Move the first test reports later.

11fde161ab selftests/clone3: skip if clone3() is ENOSYS 
If the clone3() syscall is not implemented we should skip the tests.

a019ff3b8b selftests/clone3: check that all pids are released on error paths 
This is a regression test case for an issue when pids have not been
released on error paths.

28df751539 selftests/clone3: report a correct number of fails 
In clone3_set_tid, a few test cases are running in a child process.  And
right now, if one of these test cases fails, the whole test will exit
with the success status.

Buffers have to be flushed before clone3() to avoid double messages in
the log.

41585bbeee selftests: add tests for clone3() with *set_tid 
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.
