QPID-2915 Qpid Cpp Messaging .NET Binding does not properly handle Qpid type VAR_VOID

* In C# map sender example, send null list and map values.
* In Message ToString() display "" for null list and map values.
* Do not dereference null values when determining their type.
* Properly marshal native Qpid VAR_VOID data type.
