Revision 452793

Fix for: https://issues.apache.org/activemq/browse/AMQ-942
- Added support for large string in ActiveMQStreamMessage.
- Change the marshalling method of ActiveMQStreamMessage to also use the MarshallingSupport utility. This allows a central utility to handle object marshalling. Unmarshalling was still left to ActiveMQStreamMessage as it performs type conversions.
- NOTE: The constants use to determine the data type was also change to refer to the constants in MarshallingSupport. This makes this version's wireformat incompatible with previous versions.
