[PATCH 0/7] reftable: fixes and optimizations (pt.2)

Hi,

this is the second set of patches that fixes bugs and performs some
slight memory optimizations. The series builds on top of c0cadb0576,
which has been merged to `next`.

The series is structured as follows:

  - Patch 1: some hardening to not corrupt the reftable stack on
    compaction.

  - Patch 2: fix corruption of a reftable when writing multiple indices.

  - Patches 3 - 7: various smallish refactorings to optimize memory
    usage. Overall these reduce allocations when iterating many refs by
    almost 85%.

Thanks in advance for your review!

Patrick
