* support hpcfb_show_screens()'s cb and cbarg arguments. (HPCFB_MULTI)
* emul/mapping infomation turn to per screen. * rename hpcfb_check_scroll() to hpcfb_check_update(). (HPCFB_JUMP) * rename hpcfb_scroll_update() to hpcfb_update(). (HPCFB_JUMP) * update experimental HPCFB_JUMP codes. (but not yet fix yet)
