rsync changes since last release

  ENHANCEMENTS:

    * The --delete-after option now implies --delete. (Wayne Davison)

    * The --suffix option can now be used with --backup-dir. (Michael
      Zimmerman)

    * Combining "::" syntax with the -rsh/-e option now uses the
      specified remote-shell as a transport to talk to a (newly-spawned)
      server-daemon.  This allows someone to use daemon features, such
      as modules, over a secure protocol, such as ssh. (JD Paul)

  BUG FIXES:
  
    * Fix "forward name lookup failed" errors on AIX 4.3.3.  (John
      L. Allen, Martin Pool)

    * Generate each file's rolling-checksum data as we send it, not
      in a separate (memory-eating) pass before hand.  This prevents
      timeout errors on really large files. (Stefan Nehlsen)

    * Fix compilation on Tru64.  (Albert Chin, Zoong Pham)

    * Better handling of some client-server errors.  (Martin Pool)

  INTERNAL:

    * Many code cleanups and improved internal documentation.  (Martin 
      Pool, Nelson Beebe)

    * More test cases.  (Martin Pool)

    * Updated included popt to the latest vendor drop, version 1.6.4.
