Hold function for power button to turn off the phone
In order to allow applications to use the power button, the keypad handler
will wait half a second if the key is pressed and hold, until the power
is turned off. This way the application does not need to handle it.
The power off function will then wait until the button is released, so the
phone will not start again while the button is still pressed.
