[PATCH] change rsync to allow root operations if setuid

[Gary Fernandez]

I made some changes to rsync so that it would recognize it was running as
root when run as a setuid root program. This allows the same operations as
when running as root (preserving ownership, for example).  I've attached the
diffs.
