From: Elijah Newren <newren@xxxxxxxxx>
Implement handling of normal renames. 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.)
