java: add support for parse.error=detailed

Browse Source 
In Java there is no need for N_ and yytranslate_.  So instead of
hard-coding the use of N_ in the table of the symbol names, rely on
b4_symbol_translate.

* src/output.c (prepare_symbol_names): Use b4_symbol_translate instead
of N_.
* data/skeletons/c.m4 (b4_symbol_translate): New.
* data/skeletons/lalr1.java (yysymbolName): New.
Use it.
* examples/java/calc/Calc.y: Use parse.error=detailed.
* tests/calc.at: Check parse.error=detailed.
