In the `midx.c` file, there are multiple usages of `the_repository` and
`the_hash_algo` within static functions of the file. Some of the usages
can be simply swapped out with the available `repository` struct
available. While some of them can be swapped out by passing the
repository to the required functions.
This leaves out only some other usages of `the_repository` and
`the_hash_algo` in the file in non-static functions, which we'll tackle
in upcoming commits.
