[Libvirt-cim] [PATCH 0 of 3] #3 - Enhance std association logic for reference lists and input parameter handling

Please don't ask me what happened to the patch set before and why patch 3 was not submitted to the list. So resending the complete patch set once again ... and hope. This patch set fixes: - enhance the std_assoc struct to support lists for source, target and association classnames - fixed a wrong error return for a NULL handler - reworked check for input parameter: assocClass, resultClass, role, resultRole
