bind,cmd: accept ObjC wrapper types in bound packages Accept ObjC API wrapper types as arguments and return values from bound Go package functions and methods. Also, allow Go structs to extend ObjC classes and implement ObjC protocols as well as override and implement methods. This is the third and final part of the implementation of the golang/go#17102 proposal.

mobile/bind: use objects to pass errors across the language barrier Gobind uses strings for passing errors across the language barrier. However, since Gobind doesn't have a concept of a nil string, it can't separate an empty native string from a nil string. In turn, that means that empty errors, exceptions or NSError * with an empty description are treated as no error. With ObjC, empty errors are replaced with a default string to workaround the issue, while with Java empty errors are silently ignored. Fix this by replacing strings with actual error objects, wrapping the Go error, Java Throwable or ObjC NSError *, and letting the existing bind machinery take care of passing the references across. It's a large change for a small corner case, but I believe objects are a better fit for exception that strings. Error objects also naturally leads to future additions, for example accessing the exception class name or chained exception.
