Akim Demaille 52db24b2bc java: add support for parse.error=detailed
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.

Akim Demaille d6f576102e java: examples: fix the tracking of locations
* examples/java/calc/Calc.y: The StreamTokenizer cannot "peek" for the
next character, it reads it, and keeps it for the next call.  So the
current location is one passed the end of the current token.  To avoid
this, keep the previous position, and use it to end the current token.
* examples/java/calc/Calc.test: Adjust.
