merge-recursive: New function to assist resolving renames in-core only
process_renames() and process_entry() have nearly identical code for doing three-way file merging to resolve content changes. Since we are already deferring some of the current rename handling in order to better handle D/F conflicts, it seems to make sense to defer content merging as well and remove the (nearly) duplicated code sections for handling this merging. To facilitate this process, add a new update_stages_and_entry() function which will map the higher stage index entries from two files involved in a rename into the resulting rename destination's index entries, and update the associated stage_data structure.
