In `repo_read_index_unmerged()` we read the index and then drop any unmerged entries to stage 0. In a subsequent commit we'll want to perform this operation on arbitrary indexes, not only the one of the given repository. Prepare for this by splitting out the functionality into a new function that can act on an arbitrary index. While at it, fix a signedness mismatch when iterating through the index cache entries.
