Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

Summary:
There is no point in using quint32 and casting back and forth in numerous places.
Fix a bunch of compiler warnings that we implicitly cast between signed and unsigned.
This makes things consistent with what we get from libinput.

Summary:
The new effect is based on the mouse click effect and uses the same
rendering code (this could be improved by merging them better).
Unlike mouse click there is no keyboard shortcut needed to activate:
as soon as the effect is loaded all touch points are visualized.
The visualization creates an animated circle for each touch down
position, motion and up position. The ids are tracked and each touch
id gets the same color. The first ten different touch ids get a
different color. As touch ids are stable the first finger will always
have the same color.
