apply to the indicated (sender/receiver) side.
- Added the hide/show and protect/risk filter rules as an alternate
  way to specify sender-/receiver-specific include/exclude rules.
- send_rules() now allows f_out to be -1 to indicate that the list
  should be scanned but not sent.
- send_rules() now filters the list to remove any items that don't
  apply to the current side (after sending the item to the other
  side when f_out != -1).
- {send,recv}_filter_list() now transfer the list, even when the
  receiver is the server and --delete-excluded was specified (the
  exchanged list is appropriately filtered, of course).
- recv_filter_list() uses send_rules() to trim non-applicable rules
  when we're a local-server (because we got our filter list without
  send/recv calls when fork() duplicated it).

- Updated MATCHFLGS_FROM_CONTAINER.

when --delete-excluded is set because our list has been trimmed to
only include rules that apply in the current mode.

  of all the conditional code to support that.
- Improved the comment before send_directory() to indicate that it
  gets called with f == -1 from delete_in_dir().

to the section that talked about --del being a popt alias
(which is no longer true).

- Improved --partial-dir.

  have been refused on the server daemon.  This allows us to reject
  implied options (e.g. if --partial is refused and -P specified).
- Changed the handling of the --delete refusals from the old idiom
  of upgrading "delete" to "delete*" into the new idiom of checking
  if refused_delete is set when we determine --delete was implied.
- Changed the --del option from a popt alias into a normal option.
- Mark all the daemon options as refused when a daemon is parsing
  the over-the-socket options.
- Created a new function, create_refuse_error(), which is now called
  from all the spots that check for refused options.
- Don't call clean_fname() on an empty string -- either reject it
  or handle it without erroneously expanding the string.
- If --delay-updates was specified without a --partial-dir option,
  don't send the default "--partial-dir=.~tmp~" option if the server
  is the receiver -- just let it default.

by the server, not just the partial file.

daemon excludes the dir or file), update the file without delay.

different for protocol version 29.

- Modified f_name_cmp() so that, beginning with protocol 29,
  it will guarantee that a directory name will sort one slot
  before its contents (prior versions could sort other items
  in between in rare instances).

- Only parse the "!" token when MATCHFLG_NO_PREFIXES is set if
  MATCHFLG_CVS_IGNORE is also set.

- Improved safe_fname() so that it changes all non-printable chars
  into '?'s, and accomodates more simultaneous (and longer) names.

- Changed get_cvs_excludes() to make an mflags arg.

already know about in the forked process.

- Made the match_flags var a uint32.

  recv_filter_list().  Because of this, we never skip these
  calls anymore, though read-batch processing indicates that
  the list should not really be sent by setting f_out to -1.
- Moved the definintion of the "local_server" variable here
  from options.c.

- Improved the debug info coming from add_rule().
- Changed add_filter() to parse_rule() and add_filter_file()
  to parse_filter_file().
- Changed get_filter_tok() to parse_rule_tok().
- Made the mflags a uint32.
- Added an extra arg to get_rule_prefix() to indicate if we're
  building the options for transmission or other purposes.
- The 'C' modifier can now be applied to a '-' rule, so it now
  sets a new flag: MATCHFLG_CVS_IGNORE.
- The send_filter_list() and recv_filter_list() functions now handle
  all the logic needed to do the right thing for -C (this used to be
  in main.c).
