b6f7efba48 Make sql tests build and pass with disabled deprecated APIs
Deprecated APIs of sql lib are used only in tests. This change
makes sure, that the tests build and pass with those deprecated APIs
removed or disabled, by:

- Making the parts of the tests testing the deprecated APIs to be
  compiled conditionally, only when the corresponding methods are
  enabled.

- If the test-case tests only the deprecated API, but not the
  corresponding replacement, added tests for the replacement.

c21cc647e9 Fix lancebench results oddness
Imports were expanded in the list of commands every time they were

59912b9558 Fix building examples when doing a Qt static build
The build failed due to two different reasons.

We tried to assign properties on an aliased target, which does not
work. Make sure to set properties on the original unaliased target.

We tried to query for the value of the QT_DEFAULT_PLUGINS property
when automatically linking to plugins, but the generator expression
failed in the AND section, because querying for an unexisting value
does not return an integer, and the AND expression expects an integer.
The fix is to wrap the relevant expression in a BOOL generator
expression.

qtdeclarative build, because
CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT evaluated to false due to

Instead of recomputing the value of QT_WILL_INSTALL, compute it once
while configuring qtbase, and add it to the generated

that will be built.

fecefdd369 Fix mapping of features to private features
When a feature generates a private feature, we should not just repeat
the condition but also make it depend on the original feature. In qmake
features had different outputs, while we have a 1:1 mapping. For example
the developer_build feature had "private_tests" as an output feature.
There's no condition attached to the feature and auto-detect is off, so
we'd generate

    qt_feature("developer_build" AUTODETECT OFF)
    qt_feature("private_tests" AUTODETECT OFF)

and that's wrong, because when the user enables the visible feature
(developer_build) we want it to propagate to the private_tests feature.

ce86c3373e QHostInfo: un-QObject-ify QHostInfoLookupManager
QObjects are not even reentrant, but this class must be thread-safe,
so it's always ... icky ... to have to analyze a "thread-safe
QObject", because for all intents and purposes, that's an oxymoron.

The QObject-ness isn't even used, except for defining a private slot,
connected to QCoreApplication::destroyed(). That slot just calls
waitForDone() on QThreadPool, which is a QObject itself, so use it
as the context object for the signal-slot connection, using a lambda
as slot.

So, strip the class of it's base class, convert the private slot to a
lambda and connect to that. Finally, remove the moveToThread() call,
because this new class can be destroyed from any thread, not just the
main one.

cab920d52c QSharedNetworkSessionManager: prune expired QNetworkSessions
Equality for QNetworkConfiguration is defined by identity of the
Private object, so even if there are QNCs with the same properties,
they will not compare equal. This probably happens when a user roams
through different WLANs (e.g. from work via public transport to home
and then back), and each time the home WLAN pops up, it will beget a
new QNetworkConfiguration, not comparing equal to the previous one.

So, over time, we might collect a sizeable amount of
QNetworkConfiguration objects just sitting in the cache without ever
being able to actually use an associated network session, because they
all have long since expired.

To fix, prune expired network sessions, and thus their associated
QNetworkConfigurations, from the cache. To not run every time, prune
only when this size of the cache is larger than 16 (arbitrary number).

82aabafada Fix loading of image files with wrong, but known, file name extension
If QImageReader recognized the suffix of a file, it would by default
not check if the file contents matched the claimed format. Hence, a
valid but misnamed image file would fail to load.
Fix by adding contents check for suffix-recognized files.

[ChangeLog][QtGui][Image] Loading of image files having a file name
suffix for a different image file type has been fixed. QImageReader
will now ask the suffix format handler to confirm the file contents
(canRead()), and fall back to normal file content recognition on
failure. This implies a slight behavior change in
QImageReader::loopCount(), ::imageCount() and ::nextImageDelay(): For
an unreadable file with a recognized suffix, they would earlier return
0, while they now will return -1, i.e. error as per the documentation.

de775f2e62 macOS: activate correct object when using multiple QSystemTrayIcons
Since we need to set the delegate on the defaultUserNotificationCenter,
which is a gobal object, we have to update the delegate when we show
the message. Otherwise, the last delegate created and set will receive
the notification, and the last QSystemTrayIcon created will emit the
activated signal.

Before clearing the delegate upon destruction, make sure that it's
the right item first.

Also updating coding style in the respective parts of the code, and
plugging a memory leak.

907923b7ca qmake: fix move semantics
ProFunctionDef is move-enabled, meaning its `m_pro` field can
become nullptr. Its usage in the assignment operator and the dtor
must therefore be protected with a check.

Amends 9c63ad562b.

eaceabe9ac QHostInfo: port from recursive to non-recursive mutex
It turns out that the only reason a recursive mutex is used was
because work() was locking it. But work() was only ever called from
functions that already had locked the mutex themselves, and kept it
locked across the call to work(). Clearly mark work() as expecting to
be called with the mutex held (by renaming the function to
rescheduleWithMutexHeld(), then drop the mutex locking from it.

After this change, a non-recursive mutex suffices, so save the memory
allocation and extra complexity involved with recursive mutexes.

Looking at the non-QT_CONFIG(thread) code in rescheduleWithMutexHeld(),
one might be tempted to expect a recursive mutex, since that code
calls QHostInfoRunnable::run() directly, which, in turn, recurses into
QHostInfoLookupManager whence control came, under mutex lock. But in
non-QT_CONFIG(thread) builds, QMutex is but an empty shell, all of its
operations are no-ops, so no possibility for deadlock, either.
