Don't parent (QObject) delegate items to views.

This keeps object ownership within the context the items were created
in and simplifies lifetime management as the VisualDataModel has sole
license to delete objects and doesn't have to keep guards against a
view and all it's children being deleted.

Delegates are still reparented in the item heirarchy.

Flickable containing MultiPointTouchArea is unresponsive following touch.

MPTA was releasing the mouse grab when all touches were

to its parents, who were then unable to correct their state.
Remove this code and allow the normal event handlers to do their

Optimise QQuickItem::stackAfter/Before() for the common case.

These functions are most often used to position items just given a new

to be near the end. When this is true we can save a lot of time

Ensure repeated compilation does not fail

Failure could result from the allocation of an address previously used

Detect and abort if an object is deleted during signal handling

If an object gets deleted while one of its own signal handler
expressions is being evaluated, a subsequent crash is inevitable.

While we could introduce guards/checks in the signal handler kernel
(QMetaObject::activate(), QQmlNotifier::emitNotify() and friends) to
detect and mask the sender deletion, this arguably isn't helpful; the
code that emitted the signal is likely to access member variables
directly after emitting the signal, causing semi-random crashes.

This situation is a symptom of misbehaving application code. Catch it
early rather than later, and issue a qFatal() with a helpful message.
Coupled with a backtrace, this should make it easier to track down
the flawed C++ application logic.

Improve detection of deleted VisualDataModel items.

The data object for each delegate object has a pointer guard with a

Improve composite property type unit test

Previously, the test ensured that the (variant) value returned by
QQmlProperty::read() was identical to that returned by
QMetaProperty::read(), which isn't the case if an engine is passed
to the QQmlProperty constructor. This commit expands the unit test
to ensure that the actual QObject-ptr value is identical, rather
than the variant value (which may have differing type information),
regardless of whether an engine is passed in or not.

For list properties, the individual values are (in general) not able
to be accessed, and so the unit test for list properties is relaxed.
