Sorry I lost the v6 tag on the previous series. Since then,
I merged the series with the migration ones since they touch
the same things.

Addressed almost all comments since the last post, I think just
one case where a "elif kvm" branch was kept in the powerpc/run
script because I find it convenient to add KVM specific things
there if needed.

Main changes since v6 (thanks to reviewers):
- Rebased on new stack backtrace patches, and cherry picks
  from v6.
- Move new files to SPDX headers.
- Improve comments on and simplify interrupt stack frame and
  backtracing.
- Add a docs/ directory with unittests.cfg documentation
  deduplicated from arch code and moved there, and document
  new machine= option. Not exactly 1:1 move of comments, so
  suggestions and improvements welcome there.
- Made new shell script a bit more consistent with style. I
  do have shellcheck working and some patches started, btw.,
  will look at submitting that after this series.
- Fix up a few unittests and gitlab CI to avoid failing on the
  QEMU TCG migration bug. Reduced runtime of some of the new
  migration tests.

Thanks,
Nick
