Added the ability to run unit tests in parallel on the same machine by randomly
choosing the ports the test server uses. The startServer() method picks 3 unused ports and writes them out to config-changes.ldif. It replaces the tokens "#ldapport#", "#jmxport#", and "#ldapsport#" with the port numbers. The getServerLdapPort etc. methods will return the ports assigned to those listeners.

Fix for issue 657
