... by making it thread_local.
As a natural (and welcome) side-effect, this makes output look sane in
multithreaded scenarios.
As for why it should be thread_local instead of an atomic:
Since signal emissions and slot invocations on one thread are not
necessarily correlated with another thread, they should not affect
one another's indentation level. As in, emitting QIODevice::readyRead
on a background thread should not make QEventLoop::aboutToBlock on the
main thread be indented. The only exception to this is BlockingQueued,
where one thread is directly tied to another (QTBUG-118145). But slot
invocations are anyway not currently printed for Queued connection
(see QTBUG-74099.)

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.

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.
