[MOS-550] Improve refresh of the display

1. Implement partial refresh.
2. Implement refresh canceling mechanism.
3. Refactor some parts of the gui and display code.

ad 1.
- 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.

ad 2.
- Separate display update and refresh logic.
- Divide image display message handling into two handlers, one updating
  and other one refreshing the screen.
- Add cancel refresh message and use it to cancel refresh during update.
- Store sum of refresh regions gathered during updates to refresh them
  all at once at the end.
