Add support for stored procedures in MockConnection / MockDataProvider / MockExecuteContext

[lukaseder]

Stored procedures are already supported in general, but there is currently no way of specifying results for OUT parameters.

The solution will be to use the first Record from the first MockResult returned by the MockDataProvider to generate these OUT parameters.

This functionality is missing. It was requested here:

MockConnection already has prepareCall() ?

@tomchiverton Yes: prepareCall() is available, but it (probably?) doesn't call back on the MockDataProvider when the CallableStatement is executed. Also, the way IN and OUT parameters are bound is not well defined - much like the way multiple cursors can be returned from such a call...
