Fabian Kosmale af53fb0e00 QProperty: Treat change listener modifying its source property as a loop
This is in line with QML where

import QtQuick 2.15
Rectangle {
  width: 100
  height: 100
  color: "red"
  Rectangle {
    id:  inner
    x: 10
    y: x
    width: 50
    height: 50
    onYChanged: { console.log("hey"); inner.x = 10}
    TapHandler {
      onTapped: inner.x = 20
    }
  }
}

results in a binding loop warning when the tap handler triggers. While
the change handler would only run once, we cannot statically determine
if we need to loop once, twice, or if there actually is a diverging
loop. Thus we unconditionally warn about the binding loop and stop
executing the binding.

As a drive-by, verify in the related test that a change handler which
overwrites its properties binding itself removes the binding.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
