rust-status: move to recursive traversal to prepare for parallel traversal...

rust-status: move to recursive traversal to prepare for parallel traversal I have looked into traversing the working directory in parallel either by a recursive or an iterative algorithm. The recursive approach won quite decisively both in terms of performance and code readability. You can look at my experiment here: https://heptapod.octobus.net/Alphare/rayon-recursive-traversal The chance of a stack overflow happening because the directories get too nested seems slim. This change does not yet do anything in parallel. Differential Revision: https://phab.mercurial-scm.org/D8215
