Xi: fix use of button->down - bitflags instead of int arrays.

Browse Source 
The device's button down state array was changed to use DOWN_LENGTH and thus
bitflags for each button in cfcb3da7.

Update the DBSN events to copy this bit-wise state.
Update xkb and Xi to check for the bit flag instead of the array value.

Reported by ajax.
