20d0ff1a39 QMutexLocker: add move semantics
The class is similar to unique_lock in that it allows for unlocking

it's trivial to make it movable.

9f8da21239 QDateTime: future-proof swap()
In Qt 7 32-bit builds, the ShortData will be larger than the
d-pointer.

So don't swap() the d-pointer, but a) delegate to Data to swap itself
and b) swap the ShortData there, adding a static_assert in the .cpp
file that triggers when the assumption that ShortData is always at
least as large as a pointer is violated.

Found while porting away from overly-generic qSwap(), so done that,
too.

1977c922e9 QFlatMap: make insertion STL-compatible
That is, insert() doesn't overwrite an existing entry, and range
insert inserts the first of equivalent keys' values, not the last.

This allowed this author to optimize the implementation of
makeUnique() to a O(N) algorithm (was: O(N²)). Said optimization would
have been possible with the old semantics, too, but I wrote the
algorithm first and only then noticed the broken insert() behavior is
present on QFlatMap, too, so I decided not to let good code go to
waste and to fix both problems at the same time.

In order to give users a hint of the changed semantics, make the new
API opt-in until Qt 6.5, so Qt 6.4 ships with the both the old and the
new semantics disabled, where they contradict.

58a14d9433 Enable tests to turn off Windows Vista animations
Animations in that style depend on the current time, which makes it
impossible to run baseline tests. Introduce a dynamic property that
allows us to set the time that animations use.

This way, tests can turn the animation off, or control which time should
be used.

To keep performance overhead low, check only once whether the dynamic
property is set at all.

- just default-construct 'flags', don't assign an empty string

- use qUtf16Printable() to avoid funneling UTF-16 data through 8-bit

- use a C++11 ranged for instead of a counted loop

- remove a pointless isEmpty() guard (the loop won't execute when the
  children().isEmpty())

- avoid copying object->children() (returns by cref, so it's also ok
  to stuff it directly into the ranged for loop).

f3c340c276 QStringTokenizer::toContainer(): allow more types of target containers
The previous constraint called for the value_type of the container to
exactly match the value_type of the tokenizer, which means
toContainer() could only ever work on containers of views. But there
is value in allowing QStringList, even though it works only on QL1S
needles (QStringView -> QString isn't implicit). But users may have
other types that for better or worse implicitly convert from views, so
we shouldn't over-constrain the function.

[ChangeLog][QtCore][QStringTokenizer] toContainer() now works on
containers whose value_type can be constructed from the tokenizer's
value_type. It no longer requires an exact match.

f46db29d8c Painting: fix overriding and combining different clip types
In a recent improvement (6de36918c0) the
last set clip region or path was stored in separate variables, in
order to be set again if the aliasing mode changed. That solution was
too simplistic, as it would break down as soon as more than one clip
area was set, with the latter either replacing or intersecting the
first. It was also unnecessary to introduce new storing of clip areas
and transforms, as those are already recorded in the clipInfo stack in
the painter state. This patch hence reverts much of that implementation.

However the basic idea of setting the clip area again after AA change
is good, so that part is kept, implementated instead by calling a
pre-existing function to replay the clipInfo stack.

One of the baseline test cases is extended to excercise the
combination of clip areas. As a driveby, support for setClipRectF is
added to the painting baseline test scripts, and the build of the
manual lance tool is fixed.

78073f8ab6 Restore C++20-deprecated mixed-enum bitwise operators
C++20 deprecated arithmetic on enum types. For enums used on QFlags<>,
these operators have always been user-defined, but when the two enums
are of different type, such as QFrame::Shape and QFrame::Shadow, the
deprecation warning pops up.

We have in the past fixed these in our headers by manual casts, but
that doesn't help our users when our API requires them to OR together
enums of different type.

Until we can rework these APIs to use a variadic QFlags type, we need
to fix it in an SC and BC way, which is what this patch sets out to
do.

The idea is simply to mark pairs of enums that are designed to be ORed
together and replace the deprecated built-in bitwise operators with
user-defined ones in C++20. To ensure SC and BC, we pass an explicit
result type and use that to check, in C++17 builds, that it matches
the decltype of the result of the built-in operator.

This patch is the first in a series of similar patches. It introduces
said markup macro and applies it to all enum pairs that create
warnings on (my) Linux GCC 11.3 and Clang 10.0.0 builds. It is
expected that more such markups are needed, for other modules, and for
symmetry.

Even with this patch, there is one mixed-enum warning left, in
qxcbwindow.cpp. This appears to be a genuine bug (cf. QTBUG-101306),
so this patch doesn't mark the enums involved in it as designed to be
used together.

This patch also unearthed that QT_TYPESAFE_FLAGS, possibly
unsurprisingly so, breaks several mixed bitwise flags-enum operations
(QTBUG-101344).

479c95729a Support global data tags in blacklisting identification of test-cases
Previously the blacklisting file format only worked with slot:data or
plain slot names for the items to blacklist. However, tests with
global data report themselves with the global data-row tag in the same
way as function-specific ones do; and tests which have both join the
two as slot(global:data) in the test output name, so the reader is apt
to mistake global:data for a data tag. In any case, it is potentially
desirable to be able to blacklist a function with either or both of
global and local data-row tags specified. Add support for that and
remove a blacklisting that was only needed due to the lack of this
support.

For now, make the new parameter to checkBlackLists() optional, so
that qtdeclarative's qmltest framework can adapt to this change.

68a4c5da9a Compose render-to-texture widgets through QRhi
QPlatformTextureList holds a QRhiTexture instead of GLuint. A
QPlatformBackingStore now optionally can own a QRhi and a
QRhiSwapChain for the associated window.  Non-GL rendering must use
this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still
rely on resource sharing between contexts. A widget tells that it
wants QRhi and the desired configuration in a new virtual function in
QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is
evaluated (among a top-level's all children) upon create() before
creating the repaint manager and the QWidgetWindow.

In QOpenGLWidget what do request is obvious: it will request an
OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget)
will be more interesting: it needs to honor the standard Qt Quick
env.vars. and QQuickWindow APIs (or, in whatever way the user
configured the QRhiWidget), and so will set up the config struct
accordingly.

In addition, the rhiconfig and surface type is (re)evaluated when
(re)parenting a widget to a new tlw. If needed, this will now trigger
a destroy - create on the tlw. This should be be safe to do in
setParent. When multiple child widgets report an enabled rhiconfig,
the first one (the first child encountered) wins. So e.g. attempting
to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same
top-level window will fail one of the widgets (it likely won't
render).

RasterGLSurface is no longer used by widgets. Rather, the appropriate
surface type is chosen.

The rhi support in the backingstore is usable without widgets as well.
To make rhiFlush() functional, one needs to call setRhiConfig() after
creating the QBackingStore. (like QWidget does to top-level windows)

Most of the QT_NO_OPENGL ifdefs are eliminated all over the place.
Everything with QRhi is unconditional code at compile time, except the
actual initialization.

Having to plumb the widget tlw's shareContext (or, now, the QRhi)
through QWindowPrivate is no longer needed.  The old approach does not
scale: to implement composeAndFlush (now rhiFlush) we need more than
just a QRhi object, and this way we no longer pollute everything
starting from the widget level (QWidget's topextra -> QWidgetWindow ->
QWindowPrivate) just to send data around.

The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split
is all gone. Instead, there is a QBackingStoreDefaultCompositor in
QtGui which is what the default implementations of composeAndFlush and
toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs
should continue working mostly as-is, apart from adapting to the
texture list changes and getting the native OpenGL texture id out of
the QRhiTexture)

As QQuickWidget is way too complicated to just port as-is, an rhi
manual test (rhiwidget) is introduced as a first step, in ordewr to
exercise a simple, custom render-to-texture widget that does something
using a (not necessarily OpenGL-backed) QRhi and acts as fully
functional QWidget (modeled after QOpenGLWidget). This can also form
the foundation of a potential future QRhiWidget.

It is also possible to force the QRhi-based flushing always,
regardless of the presence of render-to-texture widgets. To exercise
this, set the env.var. QT_WIDGETS_RHI=1. This picks a
platform-specific default, and can be overridden with
QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be
extended to query the platform plugin as well to check if the platform
plugin prefers to always do flushes with a 3D API.

QOpenGLWidget should work like before from the user's perspective, while
internally it has to do some things differently to play nice and prevent
regressions with the new rendering architecture. To exercise this
better, the qopenglwidget example gets a new tab-based view (that could
perhaps replace the example's main window later on?). The openglwidget
manual test is made compatible with Qt 6, and gets a counterpart in form
of the dockedopenglwidget manual test, which is a modified version of
the cube example that features dock widgets. This is relevant in
particular because render-to-texture widgets within a QDockWidget has
its own specific quirks, with logic taking this into account, hence
testing is essential.

For existing applications there are two important consequences with
this patch in place:

- Once the rhi-based composition is enabled, it stays active for the
lifetime of the top-level window.

- Dynamically creating and parenting the first render-to-texture
widget to an already created tlw will destroy and recreate the tlw
(and the underlying window). The visible effects of this depend on the
platform.  (e.g. the window may disappear and reappear on some,
whereas with other windowing systems it is not noticeable at all -
this is not really different from similar situtions with reparenting
or when moving windows between screens, so should be acceptable in
practice)

- On iOS raster windows are flushed with Metal (and rhi) from now on
(previously this was through OpenGL by making flush() call
composeAndFlush().

d743fd0d0a qDecodeDataUrl(): treat ";base64" marker as case-insensitive
RFC2397 doesn't explicitly mention it, but references RFC2045, which,
in Section 2, states:

> All media type values, subtype values, and parameter names as
> defined are case-insensitive.

and goes on, in 6.1:

>   mechanism := "7bit" / "8bit" / "binary" /
>                  "quoted-printable" / "base64" /
>                  ietf-token / x-token
>
>   These values are not case sensitive

So regardless of whether "base64" is a parameter name, or a mechanism,
we need to treat it case-insensitively.

Use QLatin1String::endsWith() instead of QByteArray::endsWith(),
because the former takes Qt::CaseInsensitive while the latter would
need a toLower().

Add a test.

As a drive-by, use the same trick for the existing case-insensitive
comparison with "charset".

As a further drive-by, fix inappropriate uses of QLatin1String (=
where they don't prevent allocations).

[ChangeLog][QtCore][QUrl] Now recognizes the ";base64" marker in
"data:" URLs case-insensitively.
