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
Diff to patch set #3:
- fixed patch 3 of 3: std_assoc_get_handler did not set handler to NULL in case of
"no valid handler found" and so returned wrong handler

Enhance handling of association's references
The source and target classnames of std_assoc are now lists,
containing all supported classnames. This approach frees
the provider from listing all possible combinations as
instances of std_assoc.

Removed error messages that cause wrong error returns
The case that no handler was found for a request caused an
error as return. This is wrong as the not-found handler
tells only, that the provider is not responsible for the
given request. In scenarios with a general request causing
the call of several association providers that return
valid instances, the former behavior causes a wrong
result, as the CIMOM would return the error and revoke all
valid results.
