By templating on the <chrono> types and unconditionally using
duration_cast to coerce the duration into a milliseconds, we
violate a principal design rule of <chrono>, namely that non-
narrowing conversions are implicit, but narrowing conversions
need duration_cast. By accepting any duration, we allow non-
sensical code such as
QTimer::singleShot(10us, ...)
to compile, which is misleading, since it's actually a zero-
timeout timer.
Overloading a non-template with a template also has adverse
effects: it breaks qOverload().
Fix by replacing the function templates with functions that
just take std::chrono::milliseconds. This way, benign code
such as
QTimer::singleShot(10s, ...)
QTimer::singleShot(10min, ...)
QTimer::singleShot(1h, ...)
work as expected, but attempts to use sub-millisecond
resolution fails to compile / needs an explicit user-
provided duration_cast.
To allow future extension to more precise timers, forcibly
inline the functions, so they don't partake in the ABI of the
class and we can later support sub-millisecond resolution by
simply taking micro- or nano- instead of milliseconds.

If QTimer::singleShot() is used with a functor callback and a context
object with different thread affinity than the caller, a crash can
occur. If the context object's thread is scheduled before
connecting to QCoreApplication::aboutToQuit(), the timer has a change
to fire and QSingleShotTimer::timerEvent() will delete the
QSingleShotTimer object making the this pointer used in the
connection invalid. This can occur relatively often if an interval
of 0 is used.
Making the moveToThread() call the last thing in the constructor
ensures that the constructor gets to run to completion before the
timer has a chance to fire.

This brings QTimer::singleShot on par with QObject::connect in

There are more opportunities in QtCore and the rest of Qt to make signals
private instead of public. This is a test-dart to see if there is any
reason not to do this.
It would be nice to make QObject::destroyed private, but as it has a
default argument it would be source incompatible to anyone connecting
to the SIGNAL(destroyed()) instead of SIGNAL(destroyed(QObject*)).
Currently the function-pointer-based connect syntax does not accept
a functor (or lambda) with a different number of arguments than the
signal. Olivier says a fix for that might come in 5.1, but for now
the qfiledialog2 test is changed to not use that anymore.
Also, the function pointer for a private signal can not be assigned to
a local variable, so the qmetamethod test is changed to not do so
anymore.

It is an extension coming from the use case when you, for instance, need to
implement a countdown timer in client codes, and manually maintain a dedicated
variable for counting down with the help of yet another Timer. There might be
other use cases as well. The returned value is meant to be in milliseconds, as
the method documentation says, since it is reasonable, and consistent with the
rest (ie. the interval accessor).
The elapsed time is already being tracked inside the event dispatcher, thus the
effort is only exposing that for all platforms supported according to the
desired timer identifier, and propagating up to the QTimer public API. It is
done by using the QTimerInfoList class in the glib and unix dispatchers, and the
WinTimeInfo struct for the windows dispatcher.
It might be a good idea to to establish a QWinTimerInfo
(qtimerinfo_win{_p.h,cpp}) in the future for resembling the interface for
windows with the glib/unix management so that it would be consistent. That would
mean abstracting out a base class (~interface) for the timer info classes.
Something like that QAbstractTimerInfo.
Test: Build test only on (Arch)Linux, Windows and Mac. I have also run the unit
tests and they passed as well.

The timer type will control the accuracy of the timer. By default, all
timers are CoarseTimers, which allows for +/- 5% interval adjustment.
PreciseTimers will not have any interval adjustments, VeryCoarseTimers
will have intervals adjusted to full second resolution.
Use QTimer::setTimerType() or the QTimer::singleShot() overload to
specify the type.
QObject::startTimer() now takes a Qt::TimerType argument which defaults
to Qt::CoarseTimer. QBasicTimer::startTimer() gets an overload that
takes a Qt::TimerType argument. The argument is unused for now, since
the QAbstractEventDispatcher interface needs to change (done in a
separate commit).
