Re: [PATCH 09/16] packfile: split up responsibilities of `reprepare_packed_git()`

> In `reprepare_packed_git()` we perform a couple of operations:
>
>   - We reload alternate object directories.
>
>   - We clear the loose object cache.
>
>   - We reprepare packfiles.

> While the logic is hosted in "packfile.c", it clearly reaches into other

> Split up the responsibility and introduce `odb_reprepare()` which now
> becomes responsible for repreparing the whole object database. The
> existing `reprepare_packed_git()` function is refactored accordingly and
> only cares about reloading the packfile store now.
