This code replaces the following from merge-recurisve.c: * the code relevant to RENAME_NORMAL in process_renames() * the RENAME_NORMAL case of process_entry() Also, there is some shared code from merge-recursive.c for multiple different rename cases which we will no longer need for this case (or other rename cases): * handle_rename_normal() * setup_rename_conflict_info() The consolidation of four separate codepaths into one is made possible by a change in design: process_renames() tweaks the conflict_info entries within opt->priv->paths such that process_entry() can then handle all the non-rename conflict types (directory/file, modify/delete, etc.) orthogonally. This means we're much less likely to miss special implementation of some kind of combination of conflict types (see commits brought in by 66c62eaec6 ("Merge branch 'en/merge-tests'", 2020-11-18), especially commit ef52778708 ("merge tests: expect improved directory/file conflict handling in ort", 2020-10-26) for more details). That, together with letting worktree/index updating be handled orthogonally in the merge_switch_to_result() function, dramatically simplifies the code for various special rename cases. (To be fair, the code for handling normal renames wasn't all that complicated beforehand, but it's still much simpler now.)
