conio: switch cursor get/set to BIOS calls, rename text-mode accessors

Browse Source 
_get_cursor/_set_cursor now use BIOS GetCursor/SetCursor (RST 8, 08Eh/084h)
instead of ESTEX CURSOR/LOCATE; cursor position packed into a two_bytes
union. get_videotextmode/set_videotextmode renamed to gettextmode/settextmode.
