'macOS' appears in the documentation frequently, and because it
resembles a variable/property name, QDoc links each occurrence
of it.

'WebChannel' appears as part of a module name, but it's also
a QML type - auto-linking each word to QML documentation is
confusing.

Likewise, there's no need to link 'OpenGL' each time.

Explicit links such as \l [QML] WebChannel continue to work.

Instead of having each platform plugin deal with application termination
in their own weird ways, we now have a QPA API to signal that the system
requested the application to terminate.

On the QGuiApplication side this results in a Quit event being sent to
the application, which triggers the default behavior of closing all app
windows, and then finally calling QCoreApplication::quit().

The quit event replaces the misuse of a close event being sent to the
application. Close events are documented as being sent to windows.

The close events that are sent to individual windows as part of the
quit process can be ignored. This will skip the final quit() of
the application, and also inform the platform that the quit was
not accepted, in case that should be propagated further.

In the future the logic for closing windows should be unified
between the various approaches in closeAllWindows, shouldQuit,
and friends.

The logic for preventing application termination when there are modal
windows active was a leftover from the Carbon to Cocoa port, and is no
longer needed. AppKit will deal with this on its own, by checking the
preventsApplicationTerminationWhenModal property of each NSWindow.

In some cases AppKit will also ignore this property, such as when
quitting the application from the menu entry, which means we now get
the default system behavior for this use-case.

We only need to use the QT_MANGLE_NAMESPACE macro when declaring the
interface of the class. As long as we couple that with an alias

of the class name can be un-namespaced, including declaring
categories on the class.

The only snag with QT_NAMESPACE_ALIAS_OBJC_CLASS is that it can
only be used once per class and translation unit, so forward
declarations get hairy, but we can avoid that by just including
the headers instead.

The childEvent handler sets the enabled property of children as they are
added to the groupbox, but applications might later enable children and
check/uncheck the groupbox's checkbox in undefined order. In that case,
we would end up with enabled children inside a conceptually disabled
groupbox (the groupbox's checkbox represents the logical "disabled"
state), which breaks documented QWidget::enabled rules.

To make sure that all children are disabled as per the state of the
groupbox, we need to run that logic once the UI has been set up, and
before it becomes visible. This is what polishing is for, so listen
for that event in addition and handle it the same way as adding (which
duplicates things, but keeps existing code that might depend on things
being updated as they are added working).

Adds the case to the existing enabledChildPropagation test case.

A default-constructed QDateTime is invalid, but compared equal to a

Fixing that then lead to some tests failing. Indeed, the original
equality check involved using toMSecsSinceEpoch(), whose value is
undefined unless the datetime is valid, without a prior check on its
validity: so ensure all uses of toMSecsSinceEpoch() are guarded with
isValid() checks.
