- Replaced the usages of deprecated APIs of corelib by corresponding
alternatives in the library code and documentation.
- Modified the tests to make them build when deprecated APIs disabled:
* Made the 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.

QTimer::singleShot is optimized for zero timeouts when using the API
taking a string method name. This optimization was not used for the API
taking a PMF or functor. This patch adds it, making the various API
calls behave similarly from a performance point of view.
The approach taken here requires a QObject context object. If none is
available, e.g. a nullptr was passed explicitly, or the
QTimer::singleShot(O, Functor) API was used, the optimization could
not easily be applied. This is not only bad from a performance POV,
but also poses as a potential source for heisenbugs: Using the
different API versions of QTimer::singleShot would use different code
paths internally, which then would not ensure the expected slot call
order. This problem actually existed already when mixing the
string-based slot syntax with PMF/functors in the QTimer::singleShot
API.
This patch overcomes this hurdle and fixes all of the above: When we
encounter a 0ms single shot timer, and no QObject context object is
available, we fall back to the main thread, or create a temporary
QObject for any other thread. The updated and extended benchmark
shows that this is still a significant performance improvement
over using a timer:

This checks that intenalHwnd in QEventDispatcherWin32::remainingTime is
initialized. If calling remaningTime, before createInternalHwnd
is called, the timeout member in the WinTimerInfo struct is not
initialized and contains a random value. This adds a check for that and
in that case returns the requested timer interval as the timer has not
yet been started. createInternalHwnd is called on the first request to
process events.
It also adds a test for checking the remaining time. But the issue can
only be seen if solely running the remainingTimeInitial test in
tst_QTimer. If running the test along side another test the other
test likely calls processEvents indirectly, which hides the issue. I
don't know if this is an issue in practice (the bug has been there
for as long a the git history goes back, 2011), but it causes the
basic_chrono test to fail if run as the only test.

The bitmap cache for the first 64 signals being connected was only set when the
connection is added. It was never unset when the connection was removed.
Internal use of the connectedSignals bitmap is not hurt by it occasionally
saying a signal is connected even though it is not, since the purpose of those
checks is avoiding expensive operations that are not necessary if nothing is
connected to the signal.
However, the public API using this cache meant that it also never spotted
signals being disconnected. This was not documented. Fix the behavior by only
using the cache if it is up to date. If it is not, use a slower path that gives
the correct answer.
To avoid making disconnections and QObject destructions slower, the cache is
only updated to unset disconnected signals when new signal connections are
added. No extra work is done in the common case where signals are only
removed in the end of the QObject's lifetime.

This feature is needed to register complex types (e.g. Q_GADGETS) at
runtime, using a single constructor method and added type parameter.
Without having the type id available to the Constructor it is impossible
to specialize behavior, thus requiring separate constructors for each
type. Generating these separate constructors at compile time is easy,
but not at runtime.
[ChangeLog][QMetaType] QMetaType can now register constructor for a set
of dynamic types.

Do not return false for loading an empty .qm file - that is, a valid

files for English translations of Qt since a while, mainly as a

Note that QCoreApplication::installTranslator() will still return
false for an empty translation file - which is ok, because it
arguably does not make much sense to install it.

The previous approach of having the signalbug helper in a subdirectory did
not work for shadow builds, as QFINDTESTDATA would not find that dir. By
putting both test and helper into the same directory, the helper will be
found in the test's current working directory.
The second problem was that not putting executables into debug/release
subdirectories might have lead to the WinRT AppxManifest being overwritten
by the wrong configuration. When Qt is configured with -release for
example, it was possible that the debug manifest (Manifest files are
always created next to the target) is written last and thus contains
debug VCLibs as a dependency.

Where possible. Sometimes the replacement is QTRY_COMPARE instead.
Also don't use QTestEventLoop directly when it can also be replaced with
QSignalSpy use.
Remove the TimerHelper class, since its uses can be done with QSignalSpy (and a
lambda when remainingTime is checked). Although checking static single-shot
timers still needs a target object, so use a stripped down version in those
tests.
remainingTimeDuringActivation() was not actually testing the repeating case, but
single-shot case twice, so fix that. In the repeating case the remaining time is
exactly 20 ms on my machine, but QEMU emulation seems to be slow enough for time
to advance before the lambda is executed, so relax the conditions.

Many subclasses of QIODevice have a functionality to block execution
until some asynchronous I/O operation completes. In case we are using
QWinEventNotifier, a typical reimplemented waitFor{ReadyRead
|BytesWritten}() function could look like:
if (WaitForSingleObject(notifier.handle(),...) == WAIT_OBJECT_0) {
notifier.setEnabled(false);
ResetEvent(notifier.handle());
bool res = GetOverlappedResult(...);
...
return true;
}
Despite the fact that the operation ends synchronously, it leaves the
notifier in a state that indicates it has received the event, so its
next call to setEnabled(true) will produce a fake notification.
So, we should reset a notifier's history before enabling it again.

There are a couple of Qt classes where you almost always use the
same signal, for example QTimer::timeout, QPushButton::clicked,
and QAction::triggered.
Simply doing timer.connectTo([]{}) is much more convenient, less
tedious and even fun.
Not overloading connect() as it would be confusing to see the
receiver as first argument.
And not naming it onTimeout, as that's a popular way of doing it in
other frameworks. People would assume you could use on* with any signal.
If we ever have on* it should be all or nothing.
[ChangeLog][QtCore] Added QTimer::connectTo(), a shorthand way of
connecting to the timeout() signal.

The Q_GADGET macro cannot be used in templates. It can however be useful
to derive a template class from a Q_GADGET enabled base class to benefit
from type safety features in C++ (e.g. the class could represent an id
or handle for some C++ type).
For proper wrapping of a QVariant with a gadget value in a QJSValue, the
QMetaType::IsGadget flag must be set for the registered template
instance type - which does not happen prior to the fix because
IsGadgetHelper requires qt_check_for_QGADGET_macro to be defined in the
registered class but not in an ancestor class - in other words: The
class must declare Q_GADGET.
To overcome this, IsGadgetHelper/IsPointerToGadgetHelper can now
differentiate between a Q_GADGET flagged class (allowing
automatic registration) and a derived class, e.g. a template class
(forcing Q_DECLARE_METATYPE to be used explicitly).

class instances inheriting from a Q_GADGET in Qml
