* Added vfs_normalize_path() service call.

* Added resolve_mount_point_to_volume_root() which does what
  resolve_volume_root_to_mount_point() did. IOW the latter one didn't
  do what it advertised.
* Fixed dir_vnode_to_path(). Basically broken due to the broken
  resolve_volume_root_to_mount_point(), but also compared potentially
  unrelated vnode IDs (belonging to different volumes).
* Fixed get_dir_path_and_leaf(). It didn't deal correctly with paths
  ending in '/' (including the root dir).
* fs_mount() does now accept a NULL fsName, getting the FS name from
  the DDM in this case.
* fs_mount() now also supports mounting file images; it lets the DDM
  create a file device for them.
