[PATCH 00/20] Stop using `the_repository` in "config.c"

Hi,

I found that there had been a bunch of callsites in code not marked with `USE_THE_REPOSITORY_VARIABLE` that still implicitly relied on `the_repository` due to calling interfaces of "config.c". This patch series has the goal of fixing that and making the dependency implicit. This is done by making "config.c" stop using `the_repository` while moving its interfaces that do use it into "config.h", guarded by the `USE_THE_REPOSITORY_VARIABLE` macro.

The series is structured as follows:

  - Patches 1 to 7 adapt "path.{c,h}" to become `the_repository`-clean.
    This is required because "config.c" relies on the "path" subsystem
    quite a lot.

  - Patches 8 and 9 introduce functions that take a `struct repository`
    where we didn't yet equivalents for the repo-less variants.

  - Patches 10 to 16 adapt various functions to take a `struct
    repository` as input.

  - Patches 17 and 18 fix up some functions that take a `struct
    repository`, but still rely on `the_repository`.

  - Patches 19 and 20 then hide config functions that rely on
    `the_repository` behind `USE_THE_REPOSITORY_VARIABLE`.

The series is built on top of `master` at 406f326d27 (The second batch, 2024-08-01) with ps/refs-wo-the-repository at 9d36dbd1ff (refs/reftable: stop using `the_repository`, 2024-07-30) merged into it.

Thanks!

Patrick
