improve public API typedef handling

[guwirth]

• support typedef union (close typedef union not supported by public API visitor #921)
• support typedef enum (close typedef enum not supported by public API visitor #974)
• in case of struct, class, union; documentation only for typedef needed and not additional for type name
• add some more test cases

Undocumented API detection does not appear to be working in Sonarqube 6.5. I assigned the rule "Public types, methods and fields (API) should be documented with Javadoc" to a Quality Profile and set it to the default profile for Java. After running sonar-scanner, nothing is flagged, even methods in the code are missing Javadoc.
