(menu_face_changed_default): New variable.

(menu_face_changed_default): New variable.
(menu_face_changed_count): Variable removed.
(Finternal_set_lisp_face_attribute): Doc fix.  If FRAME is t, set
the menu_face_changed_default flag, otherwise set the FRAME's
menu_face_changed_p flag if the `menu' face has been changed.
Prevent calling set_font_frame_param if FRAME is t.
(make_face_cache): Initialize cache's menu_face_changed_p
from menu_face_changed_default.
(realize_basic_faces): Look into the frame's face cache to
determine if the menu appearance needs updating.
