- Capture the ObjC prefix used when generating the the file.
- Track the containing type on descriptors.
- Mark descriptors where the message class name got a suffix added to it.
- Expose a fullName property on Descriptors.
- Add helpers for packing/unpacking Any messages.
- Bump the ObjC runtime version number. Since we added methods and invoke them
in the generated code, ensure the code is running against a matching version.
Otherwise, someone could compile against headers, but run with a framework
that is older and get unknown selector failures. This should trip clearer
messaging.
Fixes https://github.com/google/protobuf/issues/1674
As bazel folks are looking at getting auto generation of module maps going and
the importing of sources files causes issues there. We were only do it to
hack around some of the apple linker behaviors around objc classes and
categories, but even that isn't complete and CocoaPods was already doing -ObjC,
and developers not using pods could have still needed it to ensure everything
was linked anyways; so drop the hack of importing sources.
