Log message:
    Robert Shearman 
    Fix NdrConformantArrayBufferSize to include the size of the
    conformance value.
    Make NdrConformantArrayMemorySize do something more useful, like
    actually return the required memory.
    Conformance offset can be negative and should only be two bytes.
