sending side and the receiving side handled implicit (unsent) data.

because that's the maximum size we can transmit over the wire.

chosen, the name is sent down the name-pipe to the receiver.

- Added get_dirlist(), which returns a file_list structure for the
  desired directory, optionally with local filter rules disabled.

equal value without being equal pointers, substitute one of the
pointers for the other in the file list.  This optimizes future name
comparisons.  Note also that this optimization won't be triggered
very often (because rsync tends to send the names grouped by dir-
name at transmission time), but it's nice to be able to assume that
all files in the same dir have identical dir-name pointers after the
qsort is finished.

always dump the non-dir (because the dir might have contents in
the list).

  of storing it into the files[] array.
- Made flist_find() return "no match" if the found item differs in
  its directory-ness from the search item.
- Changed f_name_cmp() to sort sub-directories after non-directories
  for each directory's contents.  This makes things like the upcoming
  --fuzzy patch easier to get right.
- One complicating factor is that clean_flist() needed some extra
  code to ensure that a directory doesn't duplicate a non-directory
  of the same name.
- Make sure that the "strip_root" code in clean_flist() (for relative
  paths) strips off all leading slashes.

trying to stat() any items inside that dir's hierarchy.  This fixes
a bug where a symlink to a dir getting replaced by a dir with
identical contents to the dir at the other end of the symlink would
not report the updated files in the new hierarchy. (See bug #1673)

  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.
