    cpdup - Multiple additions, fixes, and one removal
    * Make -x/-X (cpignore) work with remote sources.
    * Add Makefile hack for _ST_FLAGS_PRESENT_ on FreeBSD.
    * Suppress "Handshaked with <host>" and "Not running as root"
      messages when the -q option was specified.
    * Mount points are now skipped completely.  (Before this,
      the directories and .cpignore inside them were still read.)
    * Extract scanning directories (src and dst) from DoCopy() into
      a function ScanDir(), and use ScanDir() for both src and dst.
    * Remove threads support.  It never worked very well and is
      getting in the way of new development.  The intention is to
      develop a more efficient pipelined algorithm in the future
      which does not require threading the program.
    * Use getopt(3) instead of non-standard parser, making sure
      that all options still work exactly as documented in the
      manual page.
    * Use fnmatch(3) instead of WildCmp(), adding support for
      bracket expressions (e.g. [xyz0-9]) and escaping (e.g. foo\*).
      I also suspect that fnmatch() is more efficient.
    * Use the same syntax for remote paths as scp(1), so local paths
      that contain colons can be specified (e.g. "./foo:bar");
      extract that code into its own function SplitRemote().
    * Add protocol commands hc_geteuid() and hc_getgroups().
      Use them to properly check permissions for various operations
      that would require root privileges on the target machine.
    * Bugfix:  If a symlink already existed on the target but the
      owner/group didn't match, cpdup missed to update it.
      Added a call to hc_lchown() to fix that, if privileges allow.
    * Bugfix:  The dispatch[] array wasn't initialized, so the slave
      crashed upon an unknown command instead of calling rc_badop().
    * Bump protocol version to 3 in order to be able to maintain
      backwards compatibility with older clients.
    * Bump utility version to 1.16.
    * Make the source compile with WARNS=6.
      It still doesn't pass -ansi -pedantic, though.  :-)
    * Document -j0, -k and -K in usage message (misc.c).
    * Update the manual page, fix mdoc markup and various details.
    * Add "ssh security tips" section to the BACKUPS text file.
