Patch from Tim Spriggs.

writing a batch file.

for each file given on the command-line.

that is based on the master in the new "based-on:" line.

- Improve function name: parse_rule -> parse_filter_str (to make the
  similarity with parse_filter_file clearer, and better indicate that
  it can parse multiple rules when FILTRULE_WORD_SPLIT is specified).

- In preparation for rule prefixes containing information beyond the
  rflags, change the code to pass around a full "template" filter_rule
  instead of just rflags.  Callers of parse_filter_{str,file} that want
  to specify only rflags can use rule_template(rflags) .

- Remove the MODIFIERS_* strings and instead hand-code the condition
  under which each modifier is valid.  This should make it easier to
  see that the conditions are correct.

- Tighten up default modifiers on merge rules:
  - Disallow "!" because it isn't useful.
  - If the merge rule specifies a side via "s" or "r", the rules in the
    file cannot also specify a side via "s", "r", "hide", etc.

Since the value is not needed, protocol 31 no longer sends it, while
older protocols are optimized so the sender just sends a valid rdev
value as efficiently as possible.  The receiver no longer caches an
rdev value for special files, and the generator will always pass a 0
rdev value to do_mknod() for special files. Fixes bug #6280.

dir.

- Changed get_backup_name() to verify the backup path, and make any
  missing directories.  This avoids accidental use of a symlink as a dir
  in a backup path, and gets rid of any other non-dirs that are in the
  way.  It also avoids the need for various operations to retry after
  calling make_bak_dir(), simplifying several pices of code.
- Changed create_directory_path() to make_path(), giving it flags that
  lets the caller decide if it should skip a leading slash or drop the
  trailing filename.
- Mention when we create the backup directory, so the user is not caught
  unaware when rsync uses a directory they didn't expect.
- Got rid of some dir-moving backup code that is not used.
- Added a little more backup-debug output.

if hard-linking fails.

rsync to associate the wrong ACL/xattr information with received files.

- Mention the switch from MD4 to MD5.
- Mention the default for the --log-file-format option.

Makefile-updating rule to run ./config.status.

- Avoid sending MSG_NO_SEND to the generator.
- Check if the file is wanted before discarding the batched data.
