This provides an alternative route instead of using the global `the_repository` variable. Let's modify `packfile.c` now to use this field wherever possible instead of relying on the global state. There are still a few instances of `the_repository` usage in the file, where there is no struct `packed_git` locally available, which will be fixed in the following commits.
