[PATCH 0/8] midx: stop deduplicating info redundant with their sources

[Patrick Steinhardt <ps@pks.im>]

Hi,

this patch series is a follow up to the recent patch series that started
to move the MIDX into its object source. It refactors the MIDX subsystem
so that we always read and write them via an ODB source. This ultimately
allows us to store a pointer to  the owning ODB source in the MIDX and
thus dedup some redundant information.

This series is built on top of e813a0200a7 (The fifteenth batch,
2025-07-28) with ps/object-store-midx at ec865d94d46 (midx: remove
now-unused linked list of multi-pack indices, 2025-07-15) merged into
it.

Thanks!

Patrick
