Implements an iterator API and other standard member access functions
for sequential containers so that we can use ranged-for over an object
that is a jarray. Provides read-only access to individual elements
(which is mostly relevant for arrays of objects), or the entire data()
as a contiguous memory block (which is useful for arrays of primitive
types).
QJniObject call functions can return QJniArray<T> when the return type
is either explicitly QJniArray<T> or T[], or their Qt equivalent (e.g.
a jbyteArray can be taken or returned as a QByteArray). If the return
type is a jarray type, then a QJniObject is returned as before.
Arrays can be created from a Qt container through a constructor or the
generic fromData named constructor in the QJniArrayBase class, which
implements the generic logic.
Not documented as public API yet.
Added a compile-time test to verify that types are mapped correctly.
The function test coverage is added to the QJniObject auto-test, as
that already provides the Java test class with functions taking and
returning arrays of different types.

Make the QT_D3D_NO_FLIP env.var. have an effect again.
This env.var. has the following effects:
- SwapEffect is set to DXGI_SWAP_EFFECT_DISCARD
- Scaling is set to DXGI_SCALING_STRETCH (no other option with the
blitting legacy model)
- Alpha works without having to deal with DirectComposition, the dcomp
code path is therefore skipped completely in legacy mode
- Requesting a HDR mode behaves incorrectly (there's an unwanted
conversion to SDR or something like that)
- Different window resizing artifacts. Instead of the big black/white
bars, that is typical with the modern, efficient flip swapchains in
non-Qt applications as well, there is a bit of shimmering on the
right side esp. when resizing on the left side. The option of using
the legacy is model provided mainly for users where this is
important.
- Reduced performance due the using the old blitting model, although
that probably won't be visible for many typical Qt applications on
desktop PCs.
Only for D3D11, because D3D12 does not support non-flip swapchains.
Note: this is incompatible with QT_QPA_DISABLE_REDIRECTION_SURFACE.
The reason to reintroduce this option is to provide a way, even if
just as a developer-focused environment variable, to get a behavior
that is identical to other frameworks and non-Qt applications that
still use D3D11 with the legacy swapchain modes in their rendering
engines. This applies first and foremost to window resizing, where
the visual artifacts common with flip model swapchains may be
misunderstood to be caused by Qt. Having a way to opt-in to the
legacy model allows avoiding/clarifying Apples-to-Oranges
comparisons.

Previously we had some inline c-string literals. But since the parameter
for those is const-ref QString it has to actually allocate the storage
and convert the string to UTF-16.
By putting it as a function that returns a QString constructed
with u""_s, we instead create a cheap non-owning QString that just
refers to the string somewhere in memory.
As a drive-by: move other string-literals into functions as well.

VxWorks is specific in regards to type of applications:
- static application, which do not use any dynamic libraries
- dynamic application, which uses shared libraries, and as such needs
to link against libdl.a
The latter is the only source of symbols related to dynamic loading and
thread local storage. This is an architectural decision, as application
is required to embed loading tools in itself (as opposed to Unix/Linux,
which contains dynamic loader which provides these symbols separately).
libdl.a is standard static library on VxWorks, compiled without PIC, and
as such can't be linked into shared library.
This results in compilation errors when building dynamic libraries which
use `thread_local`-related symbols, since these symbols will be
fulfilled at runtime (contained in executable which requires shared lib)
and are not available during linking.
Don't add `-Wl,--no-undefined` flag on VxWorks for Qt shared lib builds.

All these TUs relied on transitive includes of qpointer.h, maybe to a
large extent via qevent.h, though, given that qevent.h is more or less
the only public QtBase header that includes qpointer.h, something else
seems to be at play here.
Said qevent.h actually needs QPointer in-name-only, so a forward
declaration would suffice. Prepare for qevent.h dropping the include.
The algorithm I used was:
If the TU mentions 'passiveGrabbers', the name of the QEvent function
that returns QPointers, and the TU doesn't have qpointer.h included
explicitly, include it. That may produce False Positives, but better
safe than sorry. Otherwise, in src/, add an include to all source and
header files which mention QPointer. Exception: if foo.h of a foo.cpp
already includes it, don't include again.

When QDoc reads an `\fn` command it saves it to a file to parse it with
Clang, with the objective of using the produced AST to perform certain
sanity checks on the documented element.
Generally, `\fn` commands that do not represent correct C++ code are
accepted as long as Clang is still able to build an AST Node that QDoc
can work with, not resulting in any issue in the output documentation.
For example, an `\fn` that doesn't state a return type might be able to
be parsed correctly enough by Clang to produce a sensible Node for the
function that QDoc is interested into.
The documentation for `QPromise::emplaceResult/emplaceResultAt` make
use of this possibility by not stating a return type.
Up to Clang 15 this was not an issue, and a correct-enough AST was
produced when the `\fn` commands for those methods were parsed.
On Clang 16, Clang chokes on the missing return type, being unable to
recognize the function definition and produce an AST that QDoc can work
with.
This has the effect of losing those documented element in the output
documentation.
To avoid the issue, a return type is now added to the relevant `\fn`
commands.

This changes takes Qt for Android Java code away from the Delegate
classes that uses heavily Java reflection to invoke Activity/Service
calls and overrides. So instead of that, now, we have a QtActivityBase
and a QtServiceBase classes which handle the override logic needed for
Qt directly without reflection.
These Base classes extend Android's Activity and Service directly, and
are inside the internal Qt android package (under Qt6Android.jar).
For example, to handle onConfigurationChanged, instead of the current
way where we need this in QtActivityDelegate:
public void onConfigurationChanged(Configuration configuration)
{
try {
m_super_onConfigurationChanged.invoke(m_activity, configuration);
} catch (Exception e) {
e.printStackTrace();
}
handleUiModeChange(configuration.uiMode &
Configuration.UI_MODE_NIGHT_MASK);
}
And then this in QtActivity:
@Override
public void onConfigurationChanged(Configuration newConfig)
{
if (!QtLoader.invokeDelegate(newConfig).invoked)
super.onConfigurationChanged(newConfig);
}
public void super_onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
}
And having to keep it's Method handles around and then use Java
reflection
to call the override behavior done by Qt and the superclass methods.
instead of that, we can do it now in QtActivityBase like:
@Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
handleUiModeChange(newConfig.uiMode &
Configuration.UI_MODE_NIGHT_MASK);
}
Then, we would still have our user facing QtActivity class which extends
QtActivityBase and benefit from the same implementation of Qt logic done
in the base class.
An additional benefit to this approach is that now QtActivity will be
very lightweight and doesn't need to have all the boilerplate code as
before.

(QActivity, QtService and QtApplication) by implementing base
classes which use the delegate implementions directly and avoid
reflection.
