When allowing multiple down-events in a row (key autorepeat) we can't
use change_bit() any more to update the state, because autorepeat events
don't change the key state. We have to explicitly use set_bit() and
clear_bit() instead.

Now that most user interfaces are using QKeyCodes it is easier to have
common keyboard code useable by all user interfaces.
This patch adds helper code to track the state of all keyboard keys,
using a bitmap indexed by QKeyCode. Modifier state is tracked too,
as separate bitmap. That makes checking modifier state easier.
Likewise we can easily apply special handling for capslock & numlock
(toggles on keypress) and ctrl + shift (we have two keys for that).
