[Problem]      DPL::AutoPtr should replace to use standard library.
[Cause]        After C++11 is enabled, std::unique_ptr and std::shared_ptr is available.
               DPL::AutoPtr isn't necessary to exist in the DPL.
[Solution]     Remove DPL::AutoPtr
[Verification] Build packages those have dependecy with wrt-commons.
               * cert-svc uses AutoPtr which is implemented in own package.
