Add "use chroot" and "pid file" rsyncd.conf options.  The former allows one
to disable the use of chroot so rsync --daemon can be run as a non-root
user (if a non-privileged --port is used).  The latter allows one to
specify a file in which to write the process id of the daemon, which is
useful when rsync --daemon is not run from inetd.
