* Made DIR definition private, and moved it into the new dirent_private.h

Browse Source 
header.
* Added fields necessary to make it possible to retrieve more than one
  dirent from the underlying file system.
* Unless some app creates a DIR on its own to it to feed readdir(), this
  change should be binary compatible. If we find an application misbehaving,
  we can still make it a GCC4 only thing.
* fs_attr/fs_index/fs_query now all use readdir() directly (as that one
  contains the logic to iterate through a number of dirents in userspace).
