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.

When the source model of a QSortFilterProxyModel has rows removed, a
mapping is performed in order to figure out which corresponding rows in
the sorted and filtered view of the model are affected. In doing so it
constructs a vector of removal intervals which are subsequently used to
emit rowsRemoved signals. In the case where many rows are removed (e.g.
all of them), many removal intervals are identified that are often
adjacent and could be simplified, which is what this patch does. i.e.
instead of emitting 3 rowsRemoved for 0-3, 4-6, 7-12, now a single
rowsRemoved is emitted for 0-12.

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).

When first starting an Android app we have invocation order issue, to
load the platform plugin we create the default QLocale (needed by the
resource locator code to see if :/qt/etc/qt.conf exists) so when the
android platform plugin loads and creates its own QSystemLocale, the
QLocale defaultLocalePrivate is already created and pointing to
globalLocaleData which means that systemData won't be called and thus
the code that triggers the call to QLocalePrivate::updateSystemPrivate
won't be called when calling QLocale().
I thought of two ways of fixing this, one was calling
QLocalePrivate::updateSystemPrivatea() from the QAndroidSystemLocale
constructor, but giving the responsibility to not break things to the
plugin seems a little fragile, so making the check on QLocale()
seems better.
Without this patch an Android app doing
QApplication app(argc, argv);
qDebug() << QLocale().name();
qDebug() << QLocale().name();
qDebug() << QLocale::system().name();
qDebug() << QLocale().name();
would print

"ca_ES"
now it correctly prints "ca_ES" the four times.

This test executable was not flaky in the normal sense that when run, it
sometimes passes and sometimes fails. Instead, in some builds it would fail
consistently and in some builds it would pass consistently.
The first test to fail was version(ok00, default to last version) which gives
"mylib" as the library name and -1 as the library version. The description
implies that QLibrary selects the biggest or last used version when given -1.
However, versions less than 0 are not used at all. Instead the loading uses only
the name to select the library. Change the description to match.
So why did the test sometimes pass, sometimes fail? The test uses two library
projects lib and lib2 which install two different major versions of libmylib.
That includes the symbolic links:
libmylib.so -> libmylib.so.1.0.0*
libmylib.so.1 -> libmylib.so.1.0.0*
libmylib.so.1.0 -> libmylib.so.1.0.0*
libmylib.so.1.0.0*
libmylib.so -> libmylib.so.2.0.0*
libmylib.so.2 -> libmylib.so.2.0.0*
libmylib.so.2.0 -> libmylib.so.2.0.0*
libmylib.so.2.0.0*
The key thing being that both set the libmylib.so symbolic link. In a
multithreaded installation it's undefined which happens to set the link last.
The test code expected libmylib.so to point to libmylib.so.2.0.0. Ensure that by
building and installing lib2 after lib.

This was because as a member variable of the local struct the QThread object was
sometimes destructed before the signal connection quitting it was handled. Fix
that by making sure that the thread is finished before finishing the test.
Also moved connecting to the state machine's signal to be before starting the
machine. Because the counting of QStateMachine::finished signal could hit 1
after the first signal is emitted and the test could pass without the code
