Support the standard JMS property type conversion rules.
--------------------------------------------------------

                 Key: AMQCPP-241
                 URL: https://issues.apache.org/activemq/browse/AMQCPP-241
             Project: ActiveMQ C++ Client
          Issue Type: New Feature
          Components: CMS Impl, Openwire, Stomp
    Affects Versions: 3.0
            Reporter: Timothy Bish
            Assignee: Timothy Bish
             Fix For: 3.0


Currently the CMS Message interface restricts the user from calling a get method on a \
property that is not of the type that matches the call, for instance call \
getIntProperty when the value contained internally is a long would throw an \
exception.  To make this interface more flexible and to allow for stomp support to \
work properly in the new architecture it is necessary to support conversion of all \
the elements in the properties to a string type.  Since this happens automatically as \
a result of implementing the standard JMS conversion table it makes sense to do this \
in a way that's allows the CMS interface implementation to benefit from it as well.

The implementation follows the same rules as defined in the JMS API docs for the \
Message Interface.

Message properties support the following conversion table. The marked cases must be \
supported. The unmarked cases must throw a JMSException. The String-to-primitive \
conversions may throw a runtime exception if the primitive's valueOf method does not \
accept the String as a valid representation of the primitive.

A value written as the row type can be read as the column type.
