- Updated itemize() to handle sending of hard-link-name info.  Made
  it non-static so the hard-link code can now output itemized
  messages.
- Made the locally-changed items (such as dirs and symlinks) itemize
  using a new ITEM_LOCAL_CHANGE flag instead of the (renamed)
  ITEM_TRANSFER flag (formerly ITEM_UPDATING).
- Improved the hard-link support by having a cluster of hard-linked
  files get processed as soon as we notice that a single item is
  already up-to-date, or it succssfully finishes being updated.
- The hard-linking that occurs when using --link-dest will now be
  mentioned at higher levels of verbosity IFF %i is in the log-
  format.
