Akim Demaille 20b0746793 parser: improve the error message for symbol class redefinition ...

Currently our error messages include both "symbol redeclared" and
"symbol redefined", and they mean something different.  This is
obscure, let's make this clearer.

I think the idea between 'definition' vs. 'declaration' is that in the
case of the nonterminals, the actual definition is its set of rules,
so %nterm would be about declaration.  The case of %token is less
clear.

* src/symtab.c (complain_class_redefined): New.
(symbol_class_set): Use it.
Simplify the logic of this function to clearly skip its body when the
preconditions are not met.
* tests/input.at (Symbol class redefinition): New.
