Since v4,

- Fixed a 32-bit compile bug and leftover debugging prints.
- Dropped the patch to change virtio net guest announce timers
  for now.
- Increased replay_kernel.py timeout because patch 3 was just
  nudging x86_64 test over the 120s timeout when run on gitlab.
- New patch to add a non-flaky x86_64 q35 machine replay_kernel test.
- Added some workarounds for the new reverse_debugging.py test cases
  that x86_64 and aarch64 fail on, so they don't cause CI failures.

Here are some CI jobs showing successes with replay_linux.py,
replay_kernel.py, and reverse_debugging.py on aarch64, ppc64,
and x86_64 tests:
