91a869671e CMake: generate moc files for headers using Q_NAMESPACE_EXPORT too
Commit f66c1db16c introduced Q_NAMESPACE_EXPORT and cmake automoc
needs to be told to trigger moc creation for headers using that.

The default value for this variable, from cmake's
Modules/CMakeGenericSystem.cmake is
  set(CMAKE_AUTOMOC_MACRO_NAMES "Q_OBJECT" "Q_GADGET" "Q_NAMESPACE")
But it makes more sense to set this here than in upstream cmake, anyway,
given that changes to this list happen here in qtbase.

5ab8efd66a Make conflicting targets check less strict
People tend to "turn off debug and release builds" by just not building
one of the variants. For example, Qt's own rcc is built in release only,
however it is configured for debug_and_release with the same TARGET for
both.

Let qmake complain about conflicting TARGETs only we're about to build
all of those conflicting targets, i.e. if build_all is set.

When our ELF entry point function is started by the kernel, the stack is

to a preceding CALL instruction which didn't exist. This cauases a crash

b4efdd3769 Reorganise the qfloat16 auto-test
Its limits() test was rather large and had some overlap with an older
qNan() test, that needed some clean-up (it combined qfloat16 values
with double and float values in ways that caused qfloat16 to be
promoted to another type, so we weren't testing qfloat16).

Renamed the qNan() test to qNaN(), separated out the parts of it that
actually tested infinity. Moved various parts of limits() to these and
rationalised the result. Split out a properties() test from limits()
for the properties of the qfloat16 type that are supplied by its
numeric_limits. Split out a data-driven finite() test to cover some
repeated code that was in limits() and extended it to test more
values. Added more tests of isNormal().

Fixed my earlier UK-ish spelling of "optimise", in the process, and
identify the processor rather than the virtualization as the context
where the compiler errs.

7000b66f7e Remove QVector in the API of QRhiResource subclasses
Forcing users to go through a QVector, when in practice they almost
always want to source the data from an initializer list, a QVarLengthArray,
or a plain C array, is not ideal. Especially since we can reason about
the maximum number of elements in the vast majority of use cases for all
the affected lists. QRhiResource is also not copyable so we do not need
the usual machinery offered by containers. So switch to a
QVarLengthArray.

Note that a resource is not a container. The only operations we are
interested in is to be able to source data either via an initializer
list or by iterating on something, and to be able to extract the data,
in case a user wishes to set up another resource based on the existing
one.

In some cases a QVector overload is kept for source compatibility with
other modules (Qt Quick). These may be removed in the future.

Also do a similar QVector->QVarLengthArray change in the srb-related
data in the backends.

d4c17725ab De-d-pointer QRhiShaderResourceBinding
Sad to see this go since the d pointer pattern with implicit sharing
would have been perfect for this class, had this been a public API.

However, as binary compatibility will not be a concern for QRhi classes,
it is wasteful to allocate memory on every QRhiShaderResourceBinding.
This allows users, such as Qt Quick, to use QRhiShaderResourceBinding as
a cheap, simple, value class, without having to invent their own
alternatives in performance critical places.

The change brings a not insignficant improvement in certain qmlbench scenes
(the ones with thousands of unbatched geometry nodes).

4bd6cd1992 Featurize support for signaling NaN
One of our compilers for emscripten coerces all signaling NaNs to
quiet ones, so won't do any actual signaling. Anyone relying on them
to do so shall be disappointed, so it's better that they know about it
at compile-time - or, at least, have the ability to find it out.

Put the signaling NaN producers (and remaining (test) code using them)
under the control of a feature that's disabled when numeric_limits
claims double has no signaling NaN. Assume the bootstrap library
doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no
contexpr way to test that alleged signalling and quiet NaNs are
actually distinct.

Added some auto-tests for signaling NaN, including that it's distinct
from quiet NaN. Any platform on which the last fails should disable
this feature.

86876744f0 Ensure drawable size atomicity within a frame
Revert surfacePixelSize() to be a getter only. With Metal this will
mean returning the "live" layer size (and so not the
layer.drawableSize), which is in line with what we expect with other
backends.

Instead, we leave it to the swapchain's buildOrResize() to "commit"
the size by setting drawableSize on the layer. With typical
application or Qt Quick logic this ensures that layer.drawableSize is
set once and stays static until we get to process the next resize - on
the rendering thread.

This of course would still mean that there was a race when a client
queries surfacePixelSize() to set the depth-stencil buffer size that
is associated with a swapchain. (because that must happen before
calling buildOrResize() according to the current semantics)

That can however be solved in a quite elegant way, it turns out,
because we already have a flag that indicates if a QRhiRenderBuffer is
used in combination with (and only in combination with) a
swapchain. If we simply say that setting the UsedWithSwapChainOnly
flag provides automatic sizing as well (so no setPixelSize() call is
needed), clients can simply get rid of the problematic
surfacePixelSize() query and everything works.

72dd9de283 macOS: Avoid automatic resizing of layers by fixing them to top-left
When a layer is resized, e.g. during a window resize, the contents of
the layer may lag behind if the client doesn't fill the layer in
response to the window resize and corresponding expose event.

The default behavior is for Core Animation to stretch the content
to fill the layer, but this results in the content "jumping" back
and forth when the content then picks up the new size and fills
the layer.

Instead we tell Core Animation to fix the content to the top left
corner. If a layer is sized up without a corresponding layer contents
update this will result in missing/transparent pixels in the bottom
or right part of the layer, explicitly showing what the result of
the missing paint is. During debugging we also highlight this area
by adding a magenta background color to the layer.

Conversely, if the layer is sized down we don't need to resize it,
we can just keep the fixed top left position, and the content will
stay in place during the resize. This allows for optimizations
during window resizing, where we don't need to allocate new
buffers if the old buffer is larger than the new one.

We should detect the cases where there's already a delegate, and
setting up the delegate before the layer is added makes sense.
