[PATCH v2 0/8] reftable: fixes and optimizations (pt.2)

Hi,

this is the second version of my patch series that contains additional
fixes and optimizations for the reftable library. Changes compared to
v1:

  - Added a patch to not auto-compact twice in `reftable_stack_add()`,
    reported by Han-Wen.

  - Fixed an issue I've previously introduced while rebasing the patch
    series.

  - Fixed a missing header, as reported by Junio.

Due to the added patch that avoids double auto-compaction this patch
series now depends on 637e34a783 (Merge branch 'ps/reftable-fixes',
2023-12-27).
