- Improved the code that tries to avoid scanning the same dir
  twice in a row to not drop any relnamecache entries.

properly even in inc_recurse mode.  Got rid of double output, weird
output order, and outputting of implied dirs w/--no-implied-dirs.

work right.

just in case we end up talking protocol 30 in inc_recurse mode.

sends us a normal sequence of dirs, and we just skip the implied
ones.

sequence of directories in the hierarchy, and works properly when
merging things from multiple sources.

- Fixed name of PTR_EXTRA_CNT (was PTR_EXTRA_LEN).
- Added F_DIR_RELS_P() to support --relative in inc_recurse mode.

--iconv and --files-from.

  our --iconv support.
- Moved the setup of the ic_ndx value to compat.c.

- Handle setup_iconv() call in parse_arguments() so it gets set early.

- Convert protected args when -s and --iconv are active.
- Simplified the splitting of args between normal and protected.
- Relocated setup_iconv() call so that it takes effect earlier.

- Convert remote --files-from filenames when -s and --iconv are
  active.

- Don't disable inc_recurse due to --no-implied-dirs.
- Set filesfrom_convert bool.
