Hi,

this patch series converts remaining users of `the_index` to stop using
it, instead using `the_repository->index`. This gets rid of one more
global variable and brings a project over the finish line that has
started back in 2007.

I realize that this patch series is quite large, and that reviewers will
eventually start to just gloss over things because the conversions are
kind of boring, too. Also, due to the size it's quite likely to conflict
with in-flight topics. So if you think that this is too large, please
let me know and I will happily split this up into multiple series.

The motivation of these patches comes from the introduction of the ref
format extension. I found it really hard to reason about the state of
`the_repository` and would like to continue its deprecation in favor of
explicitly passing down a `struct repository *`. Getting rid of
`the_index` is a first easy step into that direction to make things more
self-contained.
