docs: Returns the udp source port range.
  It first checks the 'GLOBUS_UDP_SOURCE_PORT_RANGE' system property.
  If that system property is not set then
  'org.globus.source.udp.port.range' system property is checked.
  If that system property is not set then it returns
  the value specified in the configuration file. Returns null if the port
  range is not defined.<BR>
  The port range is in the following form: &lt;minport&gt;, &lt;maxport&gt;
  
  @return <code>String</code> the port range.
