14dece57e9 Remap QMetaType ids to create more space for builtin types
We were starting to run out of space for builtin core types.
Remap the type id's to create lots of additional space.
We now reserve the first 64k id's for Qt, and have 16k id's for
Qt Core. That should hopfully be enough for a while ;-)

16aa8c8f4d CMake: Make the Vulkan dependency of QtGui optional
Vulkan cannot be a required public dependency of QtGui, because a
vulkan-enabled build of Qt will fail on a machine where the vulkan
headers are not installed. We cannot make the vulkan dependency private,
because we have public Qt headers that include vulkan headers.

The vulkan dependency is now marked as optional, meaning consuming
projects will try to find it, but there will be no error on failure.

3685483c4b CMake: Add facility to mark package dependencies as optional
Every public dependency of a Qt module results in a find_package call in
the consuming project. But not all public dependencies are mandatory.

For example, vulkan is only needed if the user project actually uses Qt
classes that pull in vulkan headers.

This patch adds the option MARK_OPTIONAL to qt_find_package.
Dependencies that are marked as optional will not produce an error on
find failure.

a3cb002511 CMake: Reduce the number of find_dependency calls

The reason for this stunt is that we want to replace find_dependency

Fix the places where we use find_dependency() and set the "failed" state

1abea5f5f1 Partially revert "Inline QTest::qSleep()"
This change partially reverts change
a0e0b51001.

Replacing the QTest specific sleep function with QThread::msleep()
was not a good idea. The reason is that QThread::msleep() will force
the thread to sleep to x mseconds, even if a signal woke the thread
in the meantime.

This would cause qWaitFor() to not call processEvents(), in some cases,
leading to flakyness and test failures in tests that rely on timing,
such as the animation tests in Qt Qml.

f7863bfdb9 QAbstractSpinBox: don't emit update signals twice
A QAbstractSpinBox has a spinClickThresholdTimer that is detecting
if the user is doing a press'n'hold on one of the spin buttons, to
activate auto-repeat.

But if the valueChanged() handler in the application spends too much
time before it returns, the spinClickThresholdTimer will fire before
we get a chance to cancel it from the pending mouseRelease event.

The result is that the spinbox will think that the user is doing a
press'n'hold, and increment the value once more.

To avoid this, we start the timer _after_ the call to
valueChanged() instead.

ac7e518a64 [QtCore] Fix QDateTime unit test: time zone of system was used

5a47939d5c tst_QNetworkReply: Avoid race in ioGetFromHttpWithAuth
Our authentication code is race-y by design:
1. When two requests are fired off and queued at the same time in the
same QHttpNetworkConnection then if one of them encounters
"authentication required" then it will copy whatever credentials it got
to all the other channels in the connection. This is likely what the
first part of the test is testing.
2. If a later request is fired off and it includes credentials in the
url then the newly included credentials should be used instead of the
cached ones.

The race here can occurr when one socket either takes too long to
connect or the connected signal is not received early enough. Then the
first socket is used for both requests and then we can hit case #2 when
the url contains credentials.

7dd99cd488 QAuthenticator: Don't assume we haven't tried the URL credentials
It's problematic if we have already used these credentials and it
failed. Since then we emit authenticationRequired only for QNAM to
intercept it and "helpfully" suggest we use the same credentials again.

By moving on we can check the cache or ask the user about the necessary
credentials.

9021d4bbf0 QAuthenticator: Don't assume cached credentials are new
Although this is more of a QNAM thing.
In some cases what we load from the cache might be credentials we have
already tried (and failed with, thus leading us to emit the
authenticationRequired signal). With this patch we will fall through
more often and ask the user for credentials.

96bdcdacbc CMake: Implement configure -ltcg
This configure switch sets the CMake variable
CMAKE_INTERPROCEDURAL_OPTIMIZATION_<CONFIG> per release config to ON.

The feature 'ltcg' is enabled if any of the variables
CMAKE_INTERPROCEDURAL_OPTIMIZATION,
CMAKE_INTERPROCEDURAL_OPTIMIZATION_<CONFIG> are ON.

In order to implement the check, configurejson2cmake had to be extended
to be able to write extra CMake code before and after the feature
definition. This extra code can be added to a feature mapping below the
keys "cmakePrelude" and "cmakeEpilogue".
