run-tests: add "debug" mode: don't capture child output, just show it. In debug mode, we: - don't try to diff expected vs actual output - disallow --interactive - disable timeouts (warn if user tried to supply one) - don't try to parse hghave output, since we don't have the output - don't try to save output to .err file
