dpm_module_info_of becomes dpm_get_module_info, joining the other two
readers on the context in stating that a call fetches a value.
Recording an error had two entry points doing the same write: the
exported dpm_set_last_error and an internal dpm_core::set_last_error
taking a std::string. The internal one is gone and the loader calls the
exported function, so a reason reaches the context by one path whether a
module or the library records it.
