Akim Demaille 1854429e40 yacc.c: pass the parse-params to yyreport_syntax_error ...

Enhance the calculator tests: show that passing arguments to yyerror
works.

* tests/calc.at: Add a new parse-param, nerrs, which counts the number
of syntax errors in a run.
* tests/local.at: Adjust to handle the new 'nerrs' argument, when
present.

The custom error reporting function show sees the user's additional
arguments.  Let's experiment with passing them as arguments to
yyreport_syntax_error, but maybe storing them in the context would be
a bettter alternative.

* data/skeletons/yacc.c (yyreport_syntax_error): Handle the
parse-params.
* tests/calc.at, tests/local.at: Adjust.
