* dispextern.h (display_prop_intangible_p, resize_mini_window) (pixel_to_glyph_coords, mark_window_display_accurate) (compute_display_string_pos, handle_tool_bar_click) (x_intersect_rectangles, clear_mouse_face, display_tty_menu_item): * lisp.h (setup_echo_area_for_printing, message_with_string) (pos_visible_p): Use bool for boolean. * xdisp.c: Use bool, true, false intstead of int, 1, 0. Remove unnecessary forward decls. (trace_move) [DEBUG_TRACE_MOVE]: Now static. (CHECK_IT, CHECK_WINDOW_END): Now an inline function that is always defined. (check_it) [0]: (check_window_end) [oGLYPH_DEBUG && ENABLE_CHECKING]: Remove; no longer needed. (handle_stop): Prefer (X && !Y) to (X ? !Y : 0). (get_overlay_strings): Omit unnecessary casts. (forward_to_next_line_start): (Ftool_bar_height): Prefer !BOOL to (BOOL ? 0 : 1). (next_element_function): New typedef. (get_next_element): Use it. Now const. (IT_POS_VALID_AFTER_MOVE_P): Prefer !X || Y==0 to (X ? Y==0 : 1). (vmessage): Now ATTRIBUTE_FORMAT_PRINTF (1, 0), to pacify GCC 4.9.2 (display_echo_area): Prefer BOOLEXPR to BOOLEXPR ? 1 : 0. (tool_bar_item_info): Simplify. (invisible_prop): Rename from invisible_p, since it doesn't return bool. All callers changed. (x_produce_glyphs): Simplify.
