* include/grub/term.h (GRUB_TERM_LEFT, GRUB_TERM_RIGHT)
        (GRUB_TERM_UP, GRUB_TERM_DOWN, GRUB_TERM_HOME, GRUB_TERM_END)
        (GRUB_TERM_DC, GRUB_TERM_PPAGE, GRUB_TERM_NPAGE, GRUB_TERM_ESC)
        (GRUB_TERM_TAB, GRUB_TERM_BACKSPACE): New macros.

        * kern/i386/pc/startup.S: Include `<grub/term.h>'.
        (translation_table): Replace hardcoded values with macros
        provided by `<grub/term.h>'.

        * term/i386/pc/at_keyboard.c: Include `<grub/term.h>'.
        (keyboard_map): Correct/add a few values, with macros provided
        by `<grub/term.h>'.
        (keyboard_map_shift): Zero values that don't differ from their
        `keyboard_map' equivalents.
        (grub_console_checkkey): Optimize KEYBOARD_STATUS_CAPS_LOCK toggling.
        Discard the second scan code that is always sent by Caps lock.
        Only use `keyboard_map_shift' when it provides a non-zero value,
        otherwise fallback to `keyboard_map'.
