[PATCH 00/19] object-file: get rid of `the_repository`

[Patrick Steinhardt <ps@pks.im>]

Hi,

this patch series refactors "object-file.c" to get rid of the dependency
on `the_repository`. In many such cases this is done by passing in a
`struct odb_source`, which prepares us for eventually converting this
into the "loose" object source with pluggable object databases.

The patch series is built on top of a30f80fde92 (The eighth batch,
2025-07-08) with "ps/object-store" at 841a03b4046 (odb: rename
`read_object_with_reference()`, 2025-07-01) merged into it.

Thanks!

Patrick
