[cdc_rsync] Fix issue with IPV6 localhosts (#93)

Browse Source 
Fixes an issue with port forwarding when localhost on the remote
system maps to the IPV6 localhost. In that case the server would time
out on accept() since it creates an IPV4 socket, so the connection
is never established.

Also allows passing in port 0, so that it will auto-detect an
available port. This will be used in a future CL to remove the
necessity of running netstat/ss.
