  fileops: rename to "futils.h" to match function signatures
  
  Our file utils functions all have a "futils" prefix, e.g.
  `git_futils_touch`. One would thus naturally guess that their
  definitions and implementation would live in files "futils.h" and
  "futils.c", respectively, but in fact they live in "fileops.h".
  
  Rename the files to match expectations.
