clearly deprecate %name-prefix

* src/scan-gram.l (%name-prefix): Issue a deprecation warning.

* tests/calc.at, tests/headers.at, tests/input.at, tests/java.at,
* tests/javapush.at, tests/local.at: Adjust expectations.
Or disable -Wdeprecated.

* doc/bison.texi: Document that %name-prefix is replaced by %define
api.prefix.
