Reports inconsistency errors in stream handler methods.

Input and output stream handler methods annotated with @StreamListener or @StreamEmitter have various constraints. Violation of the constraints results in errors at runtime.

For example:

• Channel defined in @StreamListener value attribute may never be combined with method parameters annotated with @Input or @Output
• An input channel must be specified for a method annotated with @StreamListener
• An output channel must be specified for a method that can return a value
• An output channel cannot be specified for a method that does not return a value
• @StreamListener condition attribute cannot be set for methods that return a value
