Remove unnecessary forward decls, that were a maintenance hassle. (history_tick): Now uprintmax_t, so it's more likely to avoid overflow. All uses changed. (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer) (scrolling_window): Use ptrdiff_t, not int, for byte count. (prepare_desired_row, line_draw_cost): Use int, not unsigned, where either works. (save_current_matrix, restore_current_matrix): Use ptrdiff_t, not size_t, where either works. (init_display): Check for overflow more accurately, and without relying on undefined behavior.
