iOS: Send application state changes synchronously

The user might have a limited time to react when the application is
suspended, so we need to send the event as soon as possible.

Doc: Remove Qt Core documentation dependency to Qt QML

When generating documentation, the Qt namespace declared in Qt Core
collides with the Qt global object declared in Qt QML. This caused
the C++ Qt namespace documentation to go missing.

This change works around the issue by removing the dependency
between Qt Core and Qt QML.

centralize auxiliary lib creation

this covers convenience libraries which are linked into dlls (if we are
not building statically) and "proper" (installed) builds of 3rdparty

Fix font fallback handling with Harfbuzz and CoreText

Comparing CGFontRefs is not reliable it seems, CFEqual on them appears
to compare pointers and there's no guarantee that CTFontCopyGraphicsFont
returns the same pointer all the time.

So instead let's compare CTFontRefs, which we keep around and also provide
as input to CoreText shaping.

install convenience libraries when building statically

we don't link static libs into other static libs, so the intermediate
libs need to be installed and resolved at app link time.

iOS: Send updated expose events on application background/foregrounding

When an application has background processing enabled, for example for
communicating with an external accessory or getting location updates,
it might trigger code that does UI updates, which will kill the app as
doing UI in the background is not allowed on iOS.

We guard against this by propagating the backgrounding as updated expose
events with a non-exposed region and isExposed() returning false. This
means clients who correctly use QWindow::isExposed() to guard their
drawing code (including the scene-graph), will live to see another day.
