Marc Mutz a9e8034e8c Implement [variant.get] for QVariant [2/2]: get()
This second patch of the series implements get().

Unlike other get() implementations in Qt, don't use my trick with the
constrained friend free function here. Instead, provide the four
overloads manually, like mandated by the standard library for
std::variant (and, indeed, tuple), such that these functions can also
be used on subclasses of QVariant.

[ChangeLog][QtCore][QVariant] Implemented the type-based std::variant
access protocol (get<T>()/get_if<T>()) to allow easier access to the
contained element than the previous solution of casting data(), as
well as to allow generic code to treat QVariant and std::variant the
same. The holds_alternative<T>() function is not provided, since it's
the same as get_if<T> != nullptr. The index-based variant access
functions (get<I>()/get_if<I>()) are also not provided, because,
unlike std::variant, QVariant does not have a bounded number of
alternative types, and QMetaType IDs are not (all) compile-time
constants.

README

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.
