+ Implement %define lr.default_rules.
+ Its value describes the states that are permitted to contain
+ default rules: "all", "consistent", or "accepting".

+ Check for a valid lr.default_rules value.
+ * src/lalr.c (state_lookahead_tokens_count): If lr.default_rules
+ is "accepting", then only mark the accepting state as
+ consistent.
+ (initialize_LA): Tell state_lookahead_tokens_count whether
+ lr.default_rules is "accepting".
+ * src/tables.c (action_row): If lr.default_rules is not "all",
+ then disable default rules in inconsistent states.
+ * src/print.c (print_reductions): Use this opportunity to
+ perform some assertions about whether lr.default_rules was
+ obeyed correctly.
+ * tests/local.at (AT_TEST_TABLES_AND_PARSE): New macro that
+ helps with checking the parser tables for a grammar.
+ * tests/input.at (%define lr.default_rules invalid values): New
+ test group.
+ * tests/reduce.at (AT_TEST_LR_DEFAULT_RULES): New macro using
+ AT_TEST_TABLES_AND_PARSE.
+ (`no %define lr.default_rules'): New test group generated by
+ AT_TEST_LR_DEFAULT_RULES.
