add get_keystroke_full() helper

Switch get_raw_keystroke() to return ax instead of ah, so it returns
both scan code and ascii code of the key pressed.

Add get_keystroke_full() function which passes up ax to the caller.

The get_keystroke() function continues to return the scancode only like
it did before.  It is a thin wrapper around get_keystroke_full() now
though.
