Hi,

this is the second version of my patch series that aims to improve the
way reftable stack perform compaction.

Changes compared to v1:

  - Extract a test helper function that sets up a stack with N tables
    containing refs.

  - Reuse file descriptor that we have already stored in a local
    variable instead of calling `lock_file_fd()` a second time.

  - Remove a no-op change in the last patch.

  - Add a comment explaining why we have to allocate N+1 many table
    names.

  - Some typo fixes.

Thanks!

I haven't reviewed v1, but did skim through it. I left some comments,
(maybe they were already asked/answered) overall the series looks great
to me.
