  Disallow producing NULL character with escape sequences NULL usually terminates the strings; allowing to produce it via escape sequences may lead to undefined behaviour. - Make NULL escape sequences (e.g. `\0` and `\x0`) invalid. - Add corresponding test. - Introduce the new message: XKB_WARNING_INVALID_ESCAPE_SEQUENCE.
