[igt-dev] [PATCH i-g-t v2 3/5] lib/igt_core: add an option to show the testlist

From: Mauro Carvalho Chehab <mchehab at kernel.org>

There are several cases where we need to list the tests the same
way as igt_runner displays them.

That should not return errors on failures and should work also
when igt_simple_main() macro is used.

Ideally, it should also show dynamic subtests, but this is more
complex, specially for Kselftest/KUnit ones. So, for now, let's
not handle dynamic ones.

Add an option to produce such testlist.
