replay-dump.py script still chokes quite easily on a trace of
Linux boot, so I revived some  patches from last year that fix
the script and add some test cases for it.

The runstate patch doesn't have a test case (yet), but you can
hit the problem by replaying to the machine shutdown and then
reverse-stepping.

Thanks,
Nick

Since v1:
- Rebase onto script that now has initial v12 support.
- avocado tests now also cover replay_kernel.py because
  replay_linux.py is very heavyweight and flaky. replay_kernel is
  feasible to run in CI and general hacking.
- Rearrange replay-dump.py decoders.

  replay: allow runstate shutdown->running when replaying trace
  scripts/replay-dump.py: Update to current rr record format
  scripts/replay-dump.py: rejig decoders in event number order
  tests/avocado: excercise scripts/replay-dump.py in replay tests
