  Support reading attributes from index
  
  Depending on the operation, we need to consider gitattributes
  in both the work dir and the index.  This adds a parameter to
  all of the gitattributes related functions that allows user
  control of attribute reading behavior (i.e. prefer workdir,
  prefer index, only use index).
  
  This fix also covers allowing us to check attributes (and
  hence do diff and status) on bare repositories.
  
  This was a somewhat larger change that I hoped because it had
  to change the cache key used for gitattributes files.
