--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.

- Incremented the SUBPROTOCOL_VERSION.

lists can't overlap in inc_recurse mode.

- Added --no-i-d as a shorter no-implied-dirs.
- Changing to --no-i-r instead of --no-ir.

get_local_name() rather than using the (now removed)
new_root_dir global.

  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.

  paths, we only scan one of them in inc_recurse mode.
- When unduplicating directories in inc_recurse mode, dump the
  ealier directory if it is implied.

in inc_recurse mode, we must keep the last dir of the duplicates.

so that the FreeBSD machine in the compile farm can test.

- Improve the chances of the generator finding a match for a
  hard-link file in inc_recurse mode.

error-code that cannot be sent successfully.

- Don't use hlink_flist in hard_link_check().
- Made the prev_name logic in hard_link_check() better.
- Added an "ndx" arg to the finish_hard_link() call.  Also, set the
  prev value of any prior entries to the first finished item (which
  ensures that any item that follows a re-shuffled item (which was
  waiting for a transferred file to finish) can find the FIRST+DONE
  item.

- Tweaking the calling syntax for glob_expand().

clear out an old popt context before starting a new one.

  source transer, complain and exit.  This can help to find option
  problems were an arg to an option turns into a local-source arg,
  and the real remote-source arg will now get rejected rather than
  attempting to find a file with a colon in its name.
- We now support the ability to specify more than one remote arg using
  the ":FILENAME" idiom for additional remote filenames.
- If the --protect-args (-s) option was specified, we send just the
  "--server -s" options to the remote rsync when it is starting, and
  then the real args are sent over the socket.

- Renamed read_filesfrom_line() to read_line() and added args to allow
  the caller to control how it works.
- Added a new function, read_args(), that reads args from a file
  descriptor (using read_line()) and expands any wildcards in them.
  This function has relocated daemon code (from clientserver.c) and
  is also used by the new --protect-args (-s) option.  The new code
  also got rid of an extra strdup() that wasn't needed.
