Log message:
	Instead of attaching lookaheads and duplicating the rules being
	reduced by a state, attach the lookaheads to the reductions.
	* src/state.h (state_t): Remove the `lookaheads',
	`lookaheads_rule' member.
	(reductions_t): Add a `lookaheads' member.
	Use a regular array for the `rules'.
	* src/state.c (reductions_new): Initialize the lookaheads member
	to 0.
	(state_rule_lookaheads_print): Adjust.
	* src/state.h, src/state.c (state_reductions_find): New.
	* src/conflicts.c (resolve_sr_conflict, set_conflicts)
	(count_rr_conflicts): Adjust.
	* src/lalr.c (LArule): Remove.
	(add_lookback_edge): Adjust.
	(state_lookaheads_count): New.
	(states_lookaheads_initialize): Merge into...
	(initialize_LA): this.
	(lalr_free): Adjust.
	* src/main.c (main): Don't free nullable and derives too early: it
	is used by --verbose.
	* src/print.c, src/print_graph.c, src/tables.c: Adjust.
