[MOS-550] Implement eink partial refresh

Detect parts of the screen changed since last update and merge them into
bigger regions. These regions defines parts of the context sent to the
display.
Refresh the region covering all of the parts since this is the most time
consuming part and the size of the refreshed region doesn't change the
time much.
Refresh the whole screen if deep refresh is requested and previously
fast refresh was used. This is needed to prevent unwanted artifacts in
some cases.

Refactor some parts of the gui and display code.

While restoring system data the timer can turn off power of E-ink

also performs reversing services list to close. In this case
we do it twice so the order is wrong.

If the service is closed the governor removes connected
