- Fixed an inc_recurse problem with implied dirs not getting created

- Fixed an inc_recurse problem with implied dirs not getting created
  with the right attributes and getting omitted from the output.
- Got rid of the directory touch-up pass in inc_recurse mode again.
  This requires us to create any missing directories early, but we
  still report on what happened in the normal course of the transfer
  sequence.
- Use the FLAG_DIR_CREATED flag instead of (the removed)
  new_root_dir global.
