81bf3e68b9 Make QRingBuffer a move-only type
There's no sense in copying a ring buffer. Moving is enough. This
marks an important step on the way to preventing accidental copies of
ring buffer content, because the 'QList buffers' member can now no
longer be implicitly shared. While the compiler will still emit the
code for detach()ing, it will now never be executed.

63a35898f4 QIODevice: use QVLA to hold the ring buffers, not QList
The only users of more than one read- or write channel are the SCTP
code and QProcess. SCTP being pretty rare, optimize for the common
case of at most two QRingBuffers for reading (QProcess) and one for
writing.  Even with more channels, QVLA shouldn't be slower than QList
- on the contrary.

Need to adjust tst_toolsupport and TypeInformationVersion, as
QFilePrivate::fileName has changed.

ae6dc7d6df Fix qt_scrollRectInImage when scrolling outside of the image
We were clipping the source rect to the image, both pre and post
scrolling, but did not apply the same logic to the target position.
By computing the target position based on the already clipped source
rect we ensure that the target position is also correct.

This was causing valgrind warnings on Linux, and crashes on Windows,
when trying to test the lower level QBackingStore::scroll() function.
The reason we were not seeing this in practice was that QWidget does
its own sanitation and clipping of the arguments before passing them
on.

As a drive-by, fix the access of image to use constBits instead of a
manual cast, and rename variables to better reflect their use.

bc4570ed24 rhi: Auto-rebuild rt by tracking attachment id and generation
Unlike the shader resource binding lists that automatically recognize
in setShaderResources() when a referenced QRhiResource has been rebuilt
in the meantime (create() was called i.e. there may be completely
different native objects underneath), QRhiTextureRenderTarget has no
such thing. This leads to an asymmetric API and requires also rebuilding
the rt whenever an attachment is rebuilt:

rt = rhi->newTextureRenderTarget({ { texture } })
rt->create()
cb->beginPass(rt, ...)
texture->setPixelSize(...)
texture->create()
rt->create() // this should not be needed
cb->beginPass(rt, ...)

Avoid having to do that second rt->create().

1c24b4b8d9 Match up testlib selftest's lists of generated files
The actual files present for expected data, the test function that
selected which tests to skip and the python function to select which
to not generate data for weren't in sync with one another.

The test-code's reason for omitting three tests was that we lacked
data files for them. So generate those and skip that exception. The
generator script's code to decide which to generate didn't exclude
anything like as many, so update it to match the test-code. In the
process, save repeating a startswith test that was used both
positively and negatively, unifying two conditions.

Extend the generator script's handling of its --skip-callgrind option
by auto-setting that option if valgrind isn't available, to match the
driver program's similar skipping.

The generated data included many files for tests we skip and, as
mentioned already, lacked files for some tests we only skipped because
we lacked them. Remove the unused files, add the lacking ones.

37bc11e707 Refactor QTEST*_MAIN() implementations

varying setup in the middle. Rework in terms of a macro that defines
main() and takes the setup code as a parameter. That setup code also

the class to be used.

Reworked various testlib selftests that were using QTEST_MAIN_IMPL();
change to use the new QTEST_MAIN_WRAPPER() and TEST_MAIN_SETUP().
These might be better dealt with by supporting a second form of the
initMain() test-setup function in the test classes, that takes
references for argc and argv, to let a test massage its command-line
options.

e42fe5c775 Fix argv hacking in tst_benchlibcallgrind.cpp
It unconditionally added -callgrind to its own command-line options,

removing the -callgrind command-line option from the test and adding

the -callgrind option in the resulting recursive call.

The test now runs quickly, producing sensible output, where previously
it took a very long time. Revised the drivers to reflect this

for variant-output files for many formats. To match that, removed the

e297e80fd0 QVarLengthArray: make reallocation strongly exception safe
The old code had several bugs:

- it immediately clobbered *this with new state, before having copied
  over the elements from the old to the new buffer

- when buffer relocation threw, it would keep the new (partially-filled)
  buffer and throw away the old

- it unconditionally used std::move() for non-relocatable types, making
  it impossible to restore the original buffer when a move throws

Instead of clobbering *this with new state, do all the work on the
side and change *this only once the reallocation has happened
successfully.

Also use q_uninitialized_relocate_n() and unique_ptr in the
implementation to simplify the code. The former got the necessary
update to use std::move_if_noexcept() instead of an unconditional
std::move() for the non-relocatable case.

[ChangeLog][QtCore][QVarLengthArray] The append()-like functions are
now strongly exception safe. This means reallocation will now use
copies instead of moves, unless the value_type has a noexcept move
constructor.

    * Part 2 terminological
    * Part 3

As a result of this change the codeToLanguage() overload without

any know code. Previously a valid language was returned only if
the function argument matched the first code defined for that
language from the above list.

493a85a9e4 Widgets: setTransientParent() when a QMenu is a window
On some platforms, such as X11 and Wayland with some compositors,
QMenu could be a popup window, which should be set a transient parent
to get relative position, which is requested by Wayland.

Added transientParentWindow() for QMenuPrivate like QDialogPrivate.

84fba93ebb QThread::create(): request interruption and join on destruction
If one destroys a running QThread, so far the behavior has been to crash
(à la std::thread) -- assuming the thread hasn't already signalled that
it has finished. This behavior is hostile to solutions such as using
QThread::create(), which always require a wait() before destroying the
thread object.

We can use the opportunity to change the behavior without breaking any
valid code. Instead of crashing, inside QThread's destructor we can ask
the new thread to quit, and then join it (à la std::jthread). This
simplifies the implementation of long-living runnables and the code that
manages them.

Deploying this solution for the whole QThread class may not be entirely
painless. While no correct code would work differently with the proposed
changes, incorrect code that deletes a running thread would no longer
crash "loudly" -- instead, it might deadlock "quietly", have memory
corruptions, etc.

Hence I'm limiting this approach to only the threads created by
QThread::create(), at least for the time being. This also side-steps
perhaps the biggest problem of generalizing the approach, which is that
placing such interrupt+join logic into~QThread's destructor would cause
it to be run _after_ a QThread subclass' own destructor has run,
destroying the subclass' data members too early. This might create
an antipattern if one chooses to subclass QThread. With create(), a
subclass in question exists, and it indeed has NSDMs, but it's entirely
under our control (in fact, I'm placing the logic just in its dtor).

[ChangeLog][QtCore][QThread] Destroying a QThread object created by
QThread::create() while the thread that it manages is still running will
now automatically ask that thread to quit, and will wait until the
thread has finished. Before, this resulted in a program crash. See the
documentation of QThread::~QThread() for more details.

f898128ee2 tst_qmetatype: factor the most expensive test into its own TU
The PRINT_2ARD_TEMPLATE macro expansion alone is responsible for about
50% of the compile time and RAM requirements of tst_qmetatype.cpp. By
factoring it into its own TU, we reduce the maximum memory load on my
machine from 4.0GiB to 2.5GiB, provided we don't parallelize the
build, then we take 0.5GiB more.

This is a quick-fix for the QNX build problems currently plaguing the
CI. Going forward, we should probably have a better solution, whatever
that may be.

When deleting the last item in a chain, without it being the last item

6f542f19bf QFontDatabase (Windows): Sanitize font requests early
After the windows font engine was no longer marking everything as
scalable we started limiting the font size of requests to the maximum
of Courier when it was requested. This was a regression from 5.8 and not
in agreement with our documentation.

The problem is that we would only make the switch from Courier to
Courier New after having already gone through the foundry-lookup and
found a closest-available font size for Courier.

With this sanitization step in the backend we can make these changes
early enough that we haven't yet adjusted e.g. the font size.
