Cpp: Remove last usages of boost

* lang/cpp/src/configuration.cpp: Use std::remove_pointer.
  (Configuration::operator<<): std::for_each.
* lang/cpp/src/context.cpp: Delete manually instead of scoped ptr.
* lang/cpp/src/scdgetinfoassuantransaction.cpp: Use static_assert.
  (to_reader_list): Tokenize with getline.
