java_gen: API improvements for BundleMessages.
This commit introducesa BundleId class that models the bundle id,
and enables us to use OFBundleCtrlMsg in our usual writeRequest()
framework (in detail, we make the OFBundleCtrlMessage an OFRequest,
its response type is also OFBundleCtrlMsg).
It would be somewhat cleaner from Java's perspective to Factor
out the individual OFBundleCtrlMessage subtypes into their
own request/responses (like we do with flod_mods).
