Updated indexing for accurate progress and improved raw ndx values. The sending side now has a sorted file-list in iconv mode so that it can output progress in sorted order. Simplified the over-the-wire index values to ensure both sides will always agree on the values. Optimized the allocation of the dir_flist->sorted array on the receiving side with --iconv and incremental recursion.
- Updated the address for the FSF in the opening comment. - Standardized the format of the opening comment, including adding a brief description of what's in the file for those that lacked it. - Added some missing copyright lines. - Some minor whitespace tweaks (in a few of the files).
