[Breaking] The `my_print_error` service passes formats and args directly to `my_vsnprintf`. Just like the `my_snprintf` service, I increased this service’s major version because: * Custom suffixes are now a thing (and custom specifiers will soon no longer be). * GCC `-Wformat` now checks formats sent to them.
