From 0475460102411979ab51c365cb2bec2c05b69cb4 Mon Sep 17 00:00:00 2001
From: Jarek Kobus <jaroslaw.kobus@qt.io>
Date: Mon, 22 Jun 2020 11:06:12 +0200
Subject: Use QList instead of QVector in corelib

Applied to headers only. Source file to be changed separately.
Omitted statemachine for now to avoid conflicts.
Omitted qmetatype.h for now - to be handled later.

Task-number: QTBUG-84469
Change-Id: I317376037a62467c313467d92955ad0b7473aa97
