api.token.prefix: use code values

Browse Source 
* data/bison.m4: Remove useless (and incorrect: m4_* instead of b4_*)
default assignment to api.token.prefix.
Check that api.token.prefix is assigned code.
* tests/input.at (%define code variables): New test.
* NEWS, doc/bison.texi, tests/c++.at, tests/calc.at,
* tests/java.at, tests/local.at: Adjust to use braces.
