* src/LR0.c (new_state): Set it to 0.
* src/conflicts.h, src/conflicts.c (print_conflicts)
(free_conflicts, solve_conflicts): Rename as...
(conflicts_print, conflicts_free, conflicts_solve): these.
Adjust callers.
* src/conflicts.c (enum conflict_resolution_e)
(solved_conflicts_obstack): New, used by...
(log_resolution): this.
Adjust to attach the conflict resolution to each state.
Complete the description with the precedence/associativity
information.
(resolve_sr_conflict): Adjust.
* src/print.c (print_state): Output its solved_conflicts.
* tests/conflicts.at (Unresolved SR Conflicts)
(Solved SR Conflicts): Exercise --report=all.

5092aba5a7 * src/conflicts.c, src/conflicts.h (print_reductions): Move to...
* src/print.c: here.
(lookaheadset, shiftset): New, used as additional storage by
print_reductions.
(print_results): Adjust.

(print_actions): here.
* src/print_graph.c (print_actions): Remove dead code.

065fbd27af * src/conflicts.c (log_resolution, flush_shift)
(resolve_sr_conflict, set_conflicts, solve_conflicts)
(count_sr_conflicts, count_rr_conflicts, conflicts_output)
(conflicts_print, print_reductions): Use a state_t instead of an
integer when referring to a state.
As much as possible, depend upon nlookaheads, instead of the
`lookaheadsp' member of the following state (since lookaheads of
successive states are successive, the difference between state n + 1
and n served as the number of lookaheads for state n).
* src/lalr.c (add_lookback_edge): Likewise.
* src/print.c (print_core, print_actions, print_state)
(print_results): Likewise.
* src/print_graph.c (print_core, print_actions, print_state)
(print_graph): Likewise.
* src/conflicts.h: Adjust.
