[PATCH v2 0/2] MR3397: Draft: ucrtbase: Do not modify rewind's stack arguments on i386.

[Victor Hermann Chiletto (＠vitorhnn)]

[A mod for Fallout: New Vegas relies on rewind not modifying the first argument passed to it.](https://github.com/jazzisparis/UIO-User-Interface-Organizer/blob/426d96391f9...) Since it only links to api-ms-win-crt-stdio I've kept the thunk usage to just ucrtbase.

--
  v2: msvcrt, ucrtbase: Introduce wine_i386_rewind.
      ucrtbase/tests: Test some details about rewind's ABI.
