Re: [PATCH 2/8] midx-write: add repository field to `write_midx_context`

> The struct `write_midx_context` is used to pass context for creating
> MIDX files. Adding the repository field here ensures that most functions
> within `midx-write.c` have access to the field and can use that instead
> of the global `repository` variable. This involves passing the
> `repository` field to `write_midx_internal`. To do this, we add
> `the_repository` usage to two non-static functions, which we'll remove
> in upcoming commits.
> 
> With this, modify the static functions in `midx-write.c` to not use
> global variables. This means, either we use existing alternatives (like
> `repository` struct), or we pass down required fields from other
> functions.
