a859dc42 - Delete google::protobuf::io::FileInputStream class from our source code (#4067)

Delete google::protobuf::io::FileInputStream class from our source code (#4067) This class is already part of the protobuf-lite library. We don't need a copy here. And if we do, we must ensure the signature of every function is exactly the same as the original. However, the upstream code may get changed over time. For example, recently protobuf added a "const" modifier to the FileInputStream::GetErrno(), which may break the build if a user want to use the latest protobuf.
