Introduce options -javapkg and -prefix for gobind command. The following generates java class Testpkg with package name com.example. gobind -lang=java -javapkg=com.example testpkg The following generates objective-c files where function and type names are prefixed with ExampleTestpkg. gobind -lang=objc -prefix=Example testpkg As discussed in golang/go#9660 and golang/go#12245. Gomobile support is not yet implemented. Change-Id: Ib9e39997ce915580a5a2e25643c0c28373f27ee1 Reviewed-on: https://go-review.googlesource.com/13969 Reviewed-by: David Crawshaw <crawshaw@golang.org>
