Since we need to resolve paths (including renames) in-core first and defer checking of D/F conflicts (namely waiting to see if directories are still in the way after all paths are resolved) before updating files involved in D/F conflicts, we will need to first process_renames, then record some information about the rename needed at D/F resolution time, and then make use of that information when resolving D/F conflicts at the end.
This commit adds some relevant data structures for storing the necessary information.
