Added QFuture::then() methods to allow chaining multiple asynchronous
computations.
Continuations can use the following execution policies:
* QtFuture::Launch::Sync - the continuation will be launched in the same
thread in which the parent has been executing.
* QtFuture::Launch::Async - the continuation will be launched in a new
thread.
* QtFuture::Launch::Inherit - the continuation will inherit the launch
policy of the parent, or its thread pool (if it was using a custom one).
* Additionally then() also accepts a custom QThreadPool* instance.
Note, that if the parent future gets canceled, its continuation(s) will
be also canceled.
If the parent throws an exception, it will be propagated to the
continuation's future, unless it is caught inside the continuation
(if it has a QFuture arg).
Some example usages:
QFuture<int> future = ...;
future.then([](int res1){ ... }).then([](int res2){ ... })...
QFuture<int> future = ...;
future.then([](QFuture<int> fut1){ /* do something with fut1 */ })...
In the examples above all continuations will run in the same thread as
future.
QFuture<int> future = ...;
future.then(QtFuture::Launch::Async, [](int res1){ ... })
.then([](int res2){ ... })..
In this example the continuations will run in a new thread (but on the
same one).
QThreadPool pool;
QFuture<int> future = ...;
future.then(&pool, [](int res1){ ... })
.then([](int res2){ ... })..
In this example the continuations will run in the given thread pool.
[ChangeLog][QtCore] Added support for attaching continuations to QFuture.

NSSavePanel does not deal well with multi-part extensions, to the point
where it will fail to open if that's the only acceptable extension.
We follow Chromium's lead here and reduce the extension to its last
component, which enables selecting and saving files such as 'foo.tar.gz'.
To improve the user experience we always show file extensions when we
detect a multi-part extension. This makes it clearer what the final
extension will be, and avoids confusing macOS about the intention of
the user when choosing a file that without the final extension also
matches another known extension.

QMenu hides regularly when the user interacts with it, and manages
the firing of signals based on that. It ignores if a QAction that is
added to it fires the triggered() signal programmatically.
With QWidgetActions added to the menu, the menu usually doesn't get
interacted with directly, as the widget gets the input events.
Since the action can be added to multiple menus, neither widget nor
action can interact with the menus programmatically. Instead, the
menu needs to hide when the widget action triggers.
Test included that covers the case where a QWidgetAction is added
to multiple menus that are visible. Documentation updated, and
removed a redudant paragraph as a drive-by change.

Relevant when doing custom rendering combined with QRhi, and only for
APIs like Vulkan, where image layouts are a thing.
As shown by demo apps, it is not currently possible to implement a
correct application that renders or raytraces into a QRhiTexture's backing
VkImage, and then uses that QRhiTexture in a QRhi-based render pass.
This is because QRhi has no knowledge of the image layout if it changes
due to commands recorded by direct Vulkan calls, and not via QRhi
itself. So, except for certain simple cases, one will end up with
incorrect image layout transitions in the barriers. (at minimum this
will be caught by the validation layer)
To remedy this, add a simple function taking the layout as int (we already
do the opposite in nativeTexture()).

Instead of

one can now do
params.deviceExtensions = { "VK_KHR_get_memory_requirements2", "VK_NV_ray_tracing" };
on the QRhiVulkanInitParams passed to QRhi::create().
The environment variable stays important for Qt Quick applications, which provide no
configurability for the QRhi construction (yet). On the other hand, applications using
QRhi directly can now also use the new approach to specify the list of device extensions
to enable.
In addition, take QVulkanInfoVector<QVulkanExtension> into use. There is no reason not to
rely on the infrastructure provided by QVulkanInstance. This also implies showing an
informative warning for unsupported extensions, instead of merely failing the device
creation. (applications will likely not be able to recover of course, but at least the
reason for failing is made obvious this way)

Newer versions of QShaderBaker will now use distinct, zero-based b, t+s,

the native resource binding map (which so far we only used with Metal)
contains the SPIR-V binding -> HLSL register binding mappings.
This way we won't end up with invalid resource binding attempts (consider
that e.g. D3D11_COMMONSHADER_SAMPLER_SLOT_COUNT is only 16), just
because, for example, a combined image sampler had a binding of 18
which then got blindly mapped to s18 and t18 in HLSL.

QtDeclarative registers types in plugins, and supports un- and reloading

We therefore add private API to manually remove the types from the

Lastly, as a precaution for re-registering the types, we reset
QMetaTypeInterface::typeId to 0, as the memory is most likely not reset
to 0 when reloading the plugin.
