* src/gram.h, src/gram.c (grammar_rhs_print, grammar_rules_print):

(rule_print): Use grammar_rhs_print.
* src/print.c (print_grammar): Use grammar_rules_print.

Complete and rationalize `useless thing' warnings.
* src/symtab.h, src/symtab.c (symbol_tag_get, symbol_tag_get_n)
(symbol_tag_print): New.
Use them everywhere in place of accessing directly the tag member.
* src/gram.h, src/gram.c (rule_print): New.
Use it where a rule used to be printed `by hand'.
* src/reduce.c (nonterminals_reduce): Report the use nonterminals.
(reduce_grammar_tables): Report the useless rules.
(reduce_print): Useless things are a warning, not an error.
Report it as such.
* tests/reduce.at (Useless Nonterminals, Useless Rules):
(Reduced Automaton, Underivable Rules): Adjust.
* tests/regression.at (Web2c Report, Web2c Report): Adjust.
* tests/conflicts.at (Unresolved SR Conflicts)
(Solved SR Conflicts): Adjust.
