5edf34848a QTableView: properly deselect row when column 0 is hidden/not visible
When the first column is hidden or not visible in the current viewport,
it is not possible to deselect the current row.
Fix it by passing the correct column to
QItemSelectionModel::selectedRows() when testing if the current index is
selected.

9ab043b688 QFileSystemEngine: Consistently check for invalid file names
stat() and friends expect a null-terminated C string. There is no way to
generate anything useful from a string that has null bytes in the
middle. It's important to catch this early, as otherwise, for example, a
QDir::exists() on such a path can return true, as the path is silently
truncated.

Extend the checks for empty file names to windows and add checks for null
bytes.

03717be788 Fix: confusion in QImage paintEngine creation on shared images
During the creation of a raster paint engine in QImage::paintEngine(),
the QImage will be detached. At least old gcc versions would get
confused so that the newly created paintengine would end up in the old
QImage copy insteads of the newly detached one. Work around by
dropping the temporary engine pointer.

ffac899576 Fix the size calculation of QHeaderView when stylesheet is used
When calculating the header section size based on its contents when a
stylesheet is used, the size hints from the stylesheet are used. In case
if the stylesheet specifies only one of the sizes, the other is set to
-1. Because of this the actual content size is ignored.

The solution is to calculate the size based on the application style, in
case if it's not specified in the stylesheet.

1748dc3e2d QGroupBox: always disable children in a checkable, unchecked groupbox
The childEvent handler sets the enabled property of children as they are
added to the groupbox, but applications might later enable children and
check/uncheck the groupbox's checkbox in undefined order. In that case,
we would end up with enabled children inside a conceptually disabled
groupbox (the groupbox's checkbox represents the logical "disabled"
state), which breaks documented QWidget::enabled rules.

To make sure that all children are disabled as per the state of the
groupbox, we need to run that logic once the UI has been set up, and
before it becomes visible. This is what polishing is for, so listen
for that event in addition and handle it the same way as adding (which
duplicates things, but keeps existing code that might depend on things
being updated as they are added working).

Adds the case to the existing enabledChildPropagation test case.

[ChangeLog][QWidget][QGroupBox] Always disable children of a checkable,
unchecked group box before showing.

60deb69034 Distinguish invalid datetimes from others
A default-constructed QDateTime is invalid, but compared equal to a
valid one referencing the start of 1970.  This lead to date properties
in QML being initialized invalid but not getting an onChange if the
first value they're set to is the start of 1970.

Fixing that then lead to some tests failing. Indeed, the original
equality check involved using toMSecsSinceEpoch(), whose value is
undefined unless the datetime is valid, without a prior check on its
validity: so ensure all uses of toMSecsSinceEpoch() are guarded with
isValid() checks.

Reworked tst_QDateTime::toSecsSinceEpoch() to use its bool column
(previously unused, after separating from toTime_t(), which uses this
column for "out of time_t's range") for validity of the datetime.

[ChangeLog][QtCore][QDateTime] Invalid datetimes are now treated as
equal and less than all valid ones. They could previously be found
equal to valid datetimes.

89ec1b3618 rhi: Add support for buffer readbacks
This also marks the beginnings of significantly extending autotesting
of the resource and rendering functionality in QRhi.

Also involves fixing up the buffer operation lists like we did
for textures before. This is to ensure updates and reads on the
same batch execute in the correct order. So just have two lists:
one with buffer, one with texture operations.

Also simplify the struct layouts. No need for those inner structs
with many duplicate members. This reduces the size even, since using a
union was never an option here. Also switch to a VLA, the size is around
253 KB per batch.

The Null backend now keeps track of the QRhiBuffer data so it can return
valid results in readbacks.

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.

f1c7814a55 rhi: Remove QVectors from the data description structs as well
As usual, keep some QVector overloads around to allow Qt Quick to compile.

Color attachments and vertex input bindings get an at(index) type of
accessor, unlike any other of similar lists. This is because there the
index is significant, and sequential iteration is not the only type of
operation that is performed. Sometimes a lookup based on an index will
be needed as well.

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.

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.
