merge-recursive: introduce new functions to handle rename logic

The amount of logic in merge_trees() relative to renames was just a few
lines, but split it out into new handle_renames() and cleanup_renames()
functions to prepare for additional logic to be added to each.  No code or
logic changes, just a new place to put stuff for when the rename detection
gains additional checks.

Note that process_renames() records pointers to various information (such
as diff_filepairs) into rename_conflict_info structs.  Even though the
rename string_lists are not directly used once handle_renames() completes,
we should not immediately free the lists at the end of that function
because they store the information referenced in the rename_conflict_info,
which is used later in process_entry().  Thus the reason for a separate
cleanup_renames().
