Fix %error-verbose for conflicts resolved by %nonassoc.

* NEWS (2.5): Document.
* data/glr.c (yyreportSyntaxError): Fix this by checking
yyis_table_ninf.
* data/yacc.c (yysyntax_error): Likewise.
* data/lalr1.cc (yysyntax_error_): Fix this by checking
yytable_ninf_.
* data/lalr1.java (yysyntax_error): Likewise.
* tests/conflicts.at (%nonassoc and eof): Update expected output
and remove FIXME.

+** Verbose error messages fixed for nonassociative tokens.
+
+  When %error-verbose is specified, syntax error messages produced by
+  the generated parser include the unexpected token as well as a list of
+  expected tokens.  Previously, this list erroneously included tokens
+  that would actually induce a syntax error because conflicts for them
+  were resolved with %nonassoc.  Such tokens are now properly omitted
+  from the list.
