touchscreen: Fix kinetic scrolling when the statusbar is off.

Browse source 
The scrolling code cannot differentiate between the BUTTON_TOUCHSCREEN post
from normal touches and the one posted in the timeout callback.

To fix introduce a global special button (BUTTON_REDRAW) that results
in the desired redraw. This existed already as a local kludge for android
and is now generalized.
